Which Is the Best Rheem Tankless Water Heater?

Among the popular water heater brands is Rheem, which is considered by many as the leader in the industry. A quick search online will give you information about the lines of appliances from this brand, including Rheem tankless water heater reviews.

However, just like with everything else in the Internet, it is easy to get overwhelmed by the search results that come up. Hopefully, this article will help you understand better about the specific products we will talk about as we try to simplify the important points for consideration.

Firstly, why do we have to look into water heaters?

Many of us do not realize just how important water heaters are in our homes. They effortlessly and efficiently provide us with the much-needed hot water that we use for showering, cooking, laundry, and more.

Unfortunately, one of the downsides of traditional water heaters is their bulky (and quite honestly ugly) appearance. That is why many homeowners these days consider water heater replacement, specifically to the tankless types.

As mentioned, there are many information online about the best tankless water heater. And so for this particular article, we will try to narrow down your choices by collating Rheem hot water heater reviews.

Read carefully below, then ask around about the specific water heaters we will be mentioning, and seriously consider which one suits you and your household’s specific needs the most.

Rheem Water Heater Reviews

To begin, allow us to enumerate our three recommended Rheem water heaters that we will look into in detail later on:

  • Rheem RTGH-95DVLN 9.5 GPM Indoor Direct Vent Tankless Natural Gas Water Heater
  • Rheem RTG-64XLN 6.4 GPM Low NOx Outdoor Tankless Natural Gas Water heater
  • Rheem RTE 13 Electric Tankless Water Heater, 4 GPM

The above are all excellent water heaters, but they offer varying specifications depending on the different needs of the market.

Rheem RTGH-95DVLN 9.5 GPM Indoor Direct Vent Tankless Natural Gas Water Heater

The Rheem RTGH-95DVLN water heater weighs 79 lbs (around 35.8 kg) and has a dimension of 18.5 x 9.8 x 27.5 inches. This unit comes with a two-pipe direct system especially designed for PVC pipe.

Its special features include a self-diagnostic system that allows for easy installation—a plus for homeowners who are thinking of installing a water heater themselves. It comes with a digital display for easy monitoring and a freeze protection feature of up to -30 Fahrenheit and has a high-altitude capability of up to 8,400 ft above sea level.

Perhaps one of the more important features for this unit is the Maintenance Notice Setting that alerts you when in need of service check. It comes with a digital remote control as well.

Now what about the performance?

This model comes with a water savings setting. This decreases the water flow through the pipes as you wait for the water to reach its desired temperature, allowing you to save up to 1100 gallons of water in a year.

But more than that—this water heater by Rheem is among the most powerful of its kind. Other online Rheem tankless water heater reviews attest to this heater’s capacity to heat up to three high-flowing showers at the same time.

This is thanks to its very high flow rate of up to 9.5 gallons per minute. You are guaranteed to have a steady supply of hot water even during times of peak usage.

And because this is a condensing unit—you get to enjoy its incredible functionality without the high energy cost. Its efficiency can range from 90 to 98 percent, compared to non-condensing units with a maximum efficiency of just 80 percent.

Overall, this unit is efficient and can quickly deliver hot water, even during colder climates. Another plus is that it is relatively quiet—meaning you can have this heater running without the distracting noise.

The downside with this unit, however, is the price. It is essentially pricier than other units, which may be an issue for households not looking to spend much on a new water heater.

Servicing of the unit may also pose as an issue for some homeowners since the warranty does not cover labor, just like other tankless water heaters.

However, if price is not an issue for you and your household needs a very powerful water heater—then this Rheem is definitely for you, without a doubt.

Things we like  

Things we don’t like

  • It comes with a self-diagnostic system for easy installation.
  • It also comes with the Maintenance Notice Setting that alerts you when service check is needed.
  • It is very efficient and powerful, with the ability to supply up to 9.5 gallons of water per minute.
  • It is a condensing unit, making it very energy efficient.
  • This unit is pricier compared to other models.
  • Servicing may also be costly.

Rheem RTG-64XLN 6.4 GPM Low NOx Outdoor Tankless Natural Gas Water heater

This Rheem water heater weighs 54 lbs (around 24.4 kg) and has dimensions of 14 x 10 x 26 inches. Its weight allows you to easily lift it off the floor and stick it to strong enough walls.

This water heater is excellent for homeowners buying a tankless heater for the first time since a natural gas unit is a great choice.

In general, natural gas units are quite similar to traditional tank water heating systems. They also last longer and are stronger compared to electric types.

This particular Rheem unit can offer up to 6.4 gallons per minute, enough to supply hot water to multiple showers and sinks at the same time. Its simultaneous usage feature is a big plus, especially if you live in a bigger household or if you need high-flowing hot water supply.

While it does not match the Rheem RTGH-95DVLN model’s 9.5 GPM, 6.4 GPM is a good enough amount of hot water flow.

Other Rheem tankless water heater reviews will let you know that this particular unit has similar features as the other Rheem units. However, the RTG-64XLN unit differs in the way it pumps emissions as it is a methane unit.

Thanks to this unit’s “low NOx” function, you do not need to install very complicated venting systems. Instead, you can make use of the cheaper PVC type, allowing you to save on installation costs.

Speaking of installation, Rheem has consistently made it easy for homeowners to install their water heaters by sending in the needed wires and remote control needed to help you set up. The remote control also lets you adjust the temperature easily.

Depending on how you see it, one consideration for this particular water heater is its outdoor installation. This particular unit needs to be installed outside because placing it in an enclosed space may pose health risks due to the accumulation of fumes.

The above consideration may be an issue for some, while others may see this as a welcome feature. After all, outdoor installation lets you save much-needed indoor space.

Another downside for this particular unit is the flow rate during colder seasons. It requires double-time to heat taps during cold weathers, possibly slowing down the flow rate to 3 to 4 GPM.

Overall, this Rheem model is a good enough water heater, especially for households in need of low to moderate hot water supply. It can be installed easily and comes with useful added features.

Things we like  

Things we don’t like

  • Its “low NOx” feature helps reduce harmful emissions.
  • This allows for “simultaneous usage,” providing hot water to several showers and kitchens at the same time.
  • This Rheem unit is relatively cheaper compared to other models.
  • It has to be installed outdoors.
  • Its flow rate can be affected by the weather.
  • It is not as powerful as other units and may therefore not be suitable for bigger homes or buildings.

Rheem RTE 13 Electric Tankless Water Heater, 4 GPM

The last Rheem water heater we will look into in this article is the Rheem RTE 13 electric tankless water heater, which is popular for its compact design. It weighs just 7.3 lbs (3.3 kg) and has dimensions of 7.2 x 7.2 x 7.2 inches (yep, it is indeed small).

The use of space is obviously one of the issues that come with water heater installation. This very reason is why many homeowners opt to have their traditional water heaters replaced with the tankless types.

However, the absence of the bulky tank is not a guarantee that it will not take up space since some tankless units are bigger than the others. This makes the Rheem RTE 13 model an excellent choice for many homeowners.

Its compact size allows for easy installation and helps you save up more space. You can easily pair it with other appliances at home such as your bathroom sink, dishwasher, and kitchen sink.

This model is especially ideal for point-of-use applications. Meaning, it heats up your water when you need it especially when paired with a specific appliance.

It does not store water, and it provides you your needed hot water instantly. Furthermore, it helps you save electricity because it stops using energy when the appliance is turned off.

Because this water heater can provide up to 4 gallons of water per minute (a lot lower than the other two models discussed above), it is ideal for single shower applications. However, it can still be connected to up to two appliances like your shower and kitchen sink.

The temperature adjustment dial allows you to easily set the heater to the desired temperature. And the LED lights lets you know whether it is on active or standby mode.

Amazon reviewers give this product 4 to 5 stars, letting us know that past and present users have found this particular unit very impressive.

However, it does come with some drawbacks. For one, it supplies lower amount of hot water so it may not be recommended for bigger households.

Also, other Rheem tankless water heater reviews would tell us that the installation of this particular unit requires some other parts not included in the package. This may then add to the tankless water heater installation cost.

Overall, this Rheem water heater is a good enough water heater suitable for people living alone who do not require too much hot water at the same time. After all, 4 GPM is an adequate enough amount of water to enjoy a refreshing hot bath.

Things we like  

Things we don’t like

  • Its compact size.
  • It is relatively cheaper compared to other types.
  • It provides hot water when needed.
  • It is relatively easy to install.
  • It is not fit for bigger households.
  • The other parts needed for installation may add to the cost.

Welcome to the World of Tankless Water Heaters

We have discussed in detail the various Rheem tankless water heaters that several other online Rheem hot water heater reviews have praised.

Now the question is, is it really time to switch to a tankless water heater?

Should You Make the Switch?

The simple answer is yes. If space is an issue for you and if you are keen on saving on energy costs in the long run, then by all means, get your home a tankless water heater.

Tankless water heaters are easy to install, and they are not as complicated to operate. Furthermore, they are packed with advance features that allow for easy monitoring and control.

However, the cost of the appliance itself is one consideration you need to keep in mind. It is unfortunately true that most water heaters come at a higher price.

But with careful consideration and an informed decision making, you are guaranteed to still get your money’s worth. Eventually, most tankless water heaters prove to be economical in the long run.

Making a Choice

Over the years, we have seen the water heating industry produce high-quality appliances. And indeed, it is easy to get confused and overwhelmed as to which type to get.

One thing to keep in mind when choosing your tankless water heater is your unique needs. You need to determine what you need a tankless water heater for and the specific features you would want to find in a water heater.

Also, you have to consider your location—can you install an outdoor water heater? Do you live in snowy and colder areas?

Lastly, price is an important factor you need to keep in mind. You need to determine how much you are willing to spend on both the unit itself and the installation cost.

Final Verdict

We have discussed three excellent water heaters above. As noted, the three water heaters work depending on your specific needs.

Now, which type wins in the round up above?

We cannot give you a definite answer, unfortunately, since each type is different and serve different needs. But we can guarantee you that each type works best as long as it matches your specific needs.

For example, if your household requires a higher hot water flower rate, than the Rheem RTGH-95DVLN unit is for you. However, if price is an issue, you may opt for the Rheem RTG-64XLN unit or the Rheem RTE 13 unit if size is an important consideration for you.

We suggest you go through the above Rheem tankless water heater reviews again and carefully decide which one works best for you according to your needs. Do not hesitate to ask experts in case there are components you do not understand as well.

Good luck in your search for the best tankless hot water heater.

Easy tips to fix Titan tankless water heater issues

You may sometimes encounter a few issues when using tankless water heaters. Most of these of which can easily be resolved with just a little investigation. We now examine some of those issues and suggest some quick Titan tankless water heater troubleshooting tips to get your water running smoothly.

1

Hot water is not instant

You may turn on the water, only to be hit by a chilly spray. Remember that hot water will not arrive immediately after you turn on the tap. Water has to travel from the heater to the tap and the length between these two points determines how fast you get hot water.

This is not a problem, just a little patience and you get your hot water. All the same, if the water is still cold after a few seconds, try the following:

  • Check to ensure that the electric power is functioning well and that the water supply to the tank is sufficient. Also, ensure that the valves are open.
  • Confirm that the water pipes are not frozen; frozen pipes will not let water through.
  • Check if there is an error code on the control panel as this stops the heater from running.
2

Low pressure

If you experience low water pressure from the faucet, try the following:

  • Confirm that the main supply from the utility company has enough pressure as this impact the pressure at the point of use.
  • Confirm that there is no obstruction of the pipes, especially arising from the accumulation of mineral deposits.
  • Turn off any parallel taps that could be interfering with the supply.
3

Water is not hot enough

  • The temperature settings could be too low; check and adjust accordingly.
  • Check the plumbing cross-over; it could be mixing cold and hot water. This may arise out of a failed mixing valve. If this is the problem, get a qualified plumber to fix it.
  • There could be a sediment and lime scale buildup in the heat exchanger. Such deposits act as insulators thus prevent water from heating up. This will require you to flush and descale the heat exchanger compartment. Seek the services of a professional plumber.
4

Water is too hot

  • The temperature sensor could be broken, or poorly positioned. Position it correctly or replace it.
  • The water temperature settings may be too high. Reduce the settings to prevent scalding.
  • There could an obstruction in the plumbing or water filter thus letting in just little-heated water. Unclog the passageways.
  • Check if the showerhead or the hot water tap is clogged. This will reduce the flow of the water. Ensure you clean out these fixtures.
5

Fluctuation in water temperature

  • Check the plumbing system for a crossover problem. The crossover problem, most likely caused by a faulty mixing valve or wrong plumbing will end up interfering with the hot water supply leading to fluctuating temperatures. Rule out this problem by closing the main valve and opening the hot water tap. If after five minutes water is still running, you have a crossover problem. Let the plumber fix it.
  • Ensure the cold water filter inlet is clean. Any debris on the inlet interferes with the water supply thus limiting the water that eventually comes out. Remove and clean it, or if irreparably damaged, replace it.
  • A restriction in the flow of hot water could also lead to fluctuating temperatures. Check out the faucet aerators, shower heads, and other plumbing fixtures to rule out clogging. If this is the case, clean them by soaking in vinegar to dissolve the mineral deposits and flush them clean.

Finally, remember that…

Tankless water heaters will experience some of these issues, don’t panic. Simply apply some of the Titan tankless water heater troubleshooting tips that I have suggested for a sure, reliable supply of hot water for your bath.

Common Water Heater Problems

1

Discolored Water

  • This is a problem commonly caused by rust and build up of sediments within the tank
  • Fix it: Flush and clean the tank.
2

Water has Bad Odor

  • This is most likely as a result of bacteria in the tank as the result of the decomposition of the sacrificial anode.
  • Fix:
  • A chlorination procedure is the most often and efficient method used to eliminate bacteria from the system.
  • Alternatively, you can either clean the tank with chlorine bleach or hydrogen peroxide.
  • Your last option is to check or replace the anode rod. However, this should only come down to it as a last resort measure.
3

Low Hot Water Pressure

  • Low hot water pressure is a problem usually caused by buildup of sediment, rust, calcium deposits or other types of debris in the plumbing lines or faucets. This often occurs after the plumbing has been worked on, water heater replaced etc.
  • Sometimes the pressure will slowly decrease over a long period time, particularly if your home has been plumbed with galvanized pipe.

This problem is likely as a result of one of the following:

  • Water shut at water heater not completely open.
  • The faucet stem or aerator is clogged with sediment.
  • The faucet supply line is clogged.
  • The faucet water has been shut off or clogged.
  • The water heater dip tube is clogged.
  • The water line is leaving water heater clogged with sediment.
  • The shut off valve at water heater has malfunctioned.

Check if you are affected by one of the above issues and, since this problem is so broad and the fixes all need to be addressed in great detail, proceed accordingly, depending on your particular problem. If you feel that you don’t have enough craftsmanship to deal with the problem yourself or if the problem persists even after you’ve attempted to fix it, make sure you call a plumber

4

Relief Valve Dribbling Water

  • Normally, when a water heater heats up water inside the tank, the water expands. When this happens, the water should typically end up expanding back out the cold water inlet, back to the water supply coming into the house. However, the municipal water supply usually acts as a gigantic expansion tank so you probably won’t notice anything. The relief valve should leak from time to time to relieve the tank of excess pressure.
  • However, if the valve is leaking unexpected amounts of water:
  • The spring in relief valve could be weak.
  • The water heater pressure too high.Water shut at water heater not completely open.
  • Fix it: Fix this common by installing a thermal expansion tank to take care of the extra pressure for you.
5

Relief Valve Releasing Large Amounts of Hot Water

  • This is another common problem that mostly occurs when the valve is opened because of high temperatures. It’s usually as result of a malfunctioning thermostat not doing its job.

1

Heater doesn’t click (start)

Description: There is no audible clicking sound when upon starting the heater. This is one of the most frequent Marey tankless water heater problems.

Solution(s):

  • Confirm that the water supply fittings are properly connected with the corresponding pipes.
  • Check the battery compartment for irregularities by opening the lid on the lower right-hand side and inspecting it. Take the batteries out, gently pull the small metal tabs towards the door of the compartment, and then place the batteries back properly. Re-insert the compartment into the heater.
  • (You will need a multi-meter for this step.) Remove the front cover of the unit by removing any screws that keep it in place, then gently pull it back and open the unit. Locate the connectors that connect the battery compartment to the ignition module, and then remove them. Proceed by removing the battery compartment from the unit, and then attach the probes to the terminals of the compartment. You should be getting a reading of at least 3 volts. If you are not receiving 3 volts, you can remove the batteries and check them individually for a minimum of 1.5 volts.
  • Check your micro switch, which is the small black switch with the metal lever on the right-hand side, and two wires connected to the left-hand side. You can find this near the bottom middle of your unit, mounted to the brass water valve assembly. Open a hot water faucet and check if the switch works at this point. If the switch does not work, make sure that you’ve connected your battery compartment properly and that the switch is placed as supposed to. If the switch still doesn’t work, you may have low water pressure.
2

Heater does not light or stay lit

Description: The digital screen does not light up when the heater starts running.

Solution(s):

  • Try throttling the unit a few times, as in the case where it’s gas powered, there may be extra unwanted gas in the chamber.
  • (If you have a gas tankless water heater, make sure that all of the gas is out of the chamber before attempting this procedure.) Remove the front cover as explained above and confirm all electrical connections are firmly in place, especially the black clip on the upper right-hand side, and the ones at the middle right-hand side.
  • If you have completed the above two steps and your screen still doesn’t light up, your solenoid will need to be replaced by an expert.

This short guide covers the basics of solving two of the most frequent Marey tankless water heater problems. For more troublesome issues, and if you weren’t able to fix these on your own, don’t hesitate to contact the Marey customer support service and seek the assistance of a technician.

The hot water tap is open, but no water is coming out.

Perhaps the most common problem, this arises as a result of the water outlet being clogged by debris, ice, etc. If this is the problem you’re facing, do the following:

  • Ensure that the water inlet filter is not clearing (not clogged) or otherwise clean.
  • Check of the water heater is frozen.
  • Check your front panel for an error code being displayed. If so, refer to your manual and countercheck what problem the code points at. If there is no error code, the simple fix could turn out to be to open all the shut-off valves on the hot and cold pipes..

The water from the hot water faucet is cold

If this problem affects you, try and resolve it by doing one of the following:

  • Ensure that the water inlet filter is clean.
  • Countercheck the hot water faucet to see if it’s open wide enough.
  • If there is an error code on the front panel, follow the instructions in the user manual to find out how you can fix it.
  • Depending on your model, check for the presence of an external recirculation system. If there is a check valve on the recirculation return line, try one of the following solutions:
  • Check your cold water inlet filter for dirt or debris that may be clogging it. Either clean it on your own, or if you don’t know how, refer to the manual for instructions on the proper way of cleaning it.
  • Last option - maybe it passed the top of your head but, try opening the hot water faucet all the way.

This is usually done at the faucet furthest from the water heater.

The Water from the hot water faucet is not hot enough

  • Believe it or not, 9/10 times this happens, it’s because of not setting the temperature on the thermostat high enough. Check the thermostat to see if the temperature is set too low.
  • Alternatively, check for cross plumbing between the cold water pipes and the hot water lines.

How Navien tankless water heater works

Navien tankless water heater provides an endless supply of hot water on demand, unlike the conventional storage tank water heaters that will eventually run out of hot water.The units get activated as you open the hot water tap. Each time you turn on the faucet, shower, or other water outlets, Navien's tankless water heater will immediately detect the flow and begins to deliver the desired hot water.

Common issues in Navien tankless water heaters

Although the Navien tankless water heaters are built to such standards, this doesn’t mean you won’t run out of hot water. In its initial phase, Navien tankless water heaters had some serious issues.

Due to this, they were known for their unreliability, short bursts of cold water and other minor failings. Causing the sales of the products to be completely stopped around 2009. But luckily, they have gotten much better, and their problems were all addressed over time.

However, this doesn't mean you wouldn't come across problems while using any one of them. Some of the common errors of Navien tankless water heaters are below. We have also included the troubleshooting guide along with this:

1

Issues with the flow sensor

One of the common issues with the flow sensors is that they can easily corrode. The sudden breakdown of flow sensor results in shutting down of the unit as the buildup would impair operation.

  • There is a temporary fix where you will take the two clamps off the sensor, pull it out and blow on it. The fix recommended by Navien tankless water heater is to change the sensor over to stainless steel. Alternatively, you can replace any part to prevent this unexpected shutdown. Also, an additional fix is to install a 5-micron filter in the water inlet right before the Navien.
2

Issues with the control boards or motherboards

It is often noticed that motherboards or control boards fail relatively on a frequent basis. This type of situation occurs only when the unit fluctuates. You notice some types of abrupt on and off. Seeing this happen on a repeated basis or possibly, it ends with a failure of error code 03 (ignition failure).

  • The only real solution is to power cycle the unit (unplug and plug back in) or replaces the Navien control board.
3

Cracking Heat Exchanger

This might not happen on a frequent basis as compared to the other problems. On the other hand, the heat exchanger of the tankless water heater starts withering on an occasional basis. With time passing, because of frequent usage of the tank the state of heat exchanger deteriorates.

  • A heat exchanger should be replaced immediately; it’s a breached containment allowing exhaust gasses to enter your home. The heat exchanger is under Navien warranty.
4

It takes too long for hot water to reach the fixtures

On some occasions, you might come across some a situation, where the Navien’ tankless water heater starts getting slow. It is suggested to go deep in this situation and look for the blockage.

  • If you are using the external recirculation mode, have a contractor come in to install a recirculation return line from the faucet that is the furthest back from the water heater.
5

Water not getting hot enough

This can be one of the major problems faced by the user. The tankless water heater is known for providing hot water at a certain temperature.

  • To sort this issue, try to check if the temperature is set too low. Another thing you can do is check for cross plumbing between the cold and hot water lines.

For other little problems that are not mentioned above, you should try to reset the water heater. This can be one of the easy and workable solutions for all miscellaneous Navien tankless water heater problems.

Here, you can reset your water heater by pressing the Reset button located on the front panel. Being an all-time solution, you are better off with the tankless water heater. However, if resetting the Navien water heater and trying the other solutions listed here doesn’t work, then it’s best to call in an authorized technician for further assistance.

How Long Does It Take For a Water Heater to Heat Up?

There’s nothing quite like a hot shower on a cold day or a nice warm bath after an intense workout session. It’s perhaps one of the most relaxing experiences in the world, not to mention all the pharmaceutical benefits a warm bath or shower offers.

All the same, there’s also nothing as annoying as waiting around, unsure of the duration of the wait before that glorious water is finally ready. Worry not, because here’s a quick rundown that will help you answer that incredibly important question - how long does it take for a water heater to heat up?

This depends majorly on the kind of heater you’re using to heat up the water (other factors like atmospheric pressure and room temperature have intentionally been omitted as they aren’t in any one person’s control) since different heat sources certainly outperform others. This quick guide should help you figure out just that.

Another reason you should probably know how long does it take for a water heater to heat up is to alleviate the possibility of Legionnaires' disease (just think of it as the opposite of typical pneumonia - it’s caused by excessive heat, rather than excessive cold).

In this guide, however, you should keep the following in mind:

  • A thermal unit is a measurement of the amount of energy required to raise the temperature of a pound of water by one degree Fahrenheit.
  • The temperature at which water is considered safe is 122 degrees Fahrenheit.
  • 1 gallon of water is equal to approximately 8.3 pounds.

The Gas Water Heater

How long does it take for a water heater to heat up in the event that particular heater is a gas water heater?

An average amount of water held by a gas water heater is about 40 gallons of water, which allows entering of the supply at an average of 70 degrees Fahrenheit (slightly below room temperature). All factors kept constant, a gallon of water requires about 8.7kj of energy to raise its temperature by one degree, translating in about 30 - 40 minutes for the water to climb up by the remaining 52 degrees and be considered safe.

Your best bet for how long it takes to heat up water with a good gas water heater is about half an hour.

Electric Water Heater

Generally speaking, gas water heaters tend to be cheaper and more efficient than electric water heaters. In fact, as long as you think along those lines, it’s worth noting that electric heaters are also slower than the average gas water heater.

Once again, all factors kept constant, you’re looking at about an hour or hour and a half to heat up about 40 gallons of water from room temperature into the safe zone. However, if you’re looking to improve this stellar performance even further, consider investing in a good rinnai tankless water heater. It’s your safest best at quickly heating water.

Tankless Water Heater

Assuming you have a good tankless water heater in your hands, completely unflawed and of the top quality, a tankless water heater should do the job almost instantly.

The tankless water heater is relatively new technology, which, unlike other beforehand mentioned water heaters, doesn’t store any water on its own. Since there is no stored water to be heated and in the process of constantly consuming energy, there’s theoretically no limit to the amount of water being supplied and heated as it transfers through the device and straight into the home, you have on your hands an unlimited supply of almost instantly hot water.

It’s a novel idea, and relatively new to the market, but a good tankless water heater is your safest bet for a ready supply of fresh, hot water. That way, you don’t ever have to wait for your water to heat up, and you save lots of energy in the process. All you need is a good tankless water heater.

Solar Water Heater

The solar water heater comes last on the list but is by no means incapable of achieving the desirable results, at times even evenly matching the amount of time required by an electric water heater.

Typically, solar energy is converted to electric energy and this is used to heat up the water, but, of course, your main hindrance is, well, the sun. On a nice, hot sunny day, it should take about an hour to an hour and a half. Better is that you have a backup power source. A dull cloudy Monday won’t affect you in this case.

How long does it take for a water heater to heat up? It really depends on the technology you’re using, but your safest bet is a good tankless water heater - it’s almost instant!

Tankless Water Heaters–Are They Right For You?

Tankless water heaters have been around for quite some time now, offering a whole new water heating experience by reducing bills and making it more momentarily interactive instead of a daily premise. With a tankless water heater, you don’t need to think about turning anything on or off beforehand. Simply flick it on whenever hot water is needed and it will provide as much as necessary. But, how to select a tankless water heater?

​A tankless water heater may appear complicated to an average Joe, while it’s actually anything but. It’s composed of no more than 7-8 parts, all of which are quite simple to grasp. Mainly, once you connect your water heater to your water supply and turn the shower valve, the cold water that enters it will trigger the water sensor, which will then signal the computer to start the heating process. The water will circulate around and through the ignited heat exchanger a few times, after which it will have the desired temperature.

​One of the few things that you do have to think about when it comes to using a tankless water heater is the price. They most definitely aren’t a cheap appliance, but some of them are quite affordable and yet extremely well-made. Consequently, an economical but great tankless water heater is an almost irreplaceable upgrade to your household.

Another considerable fact is that a good majority of these products is gas-powered, meaning you do need to plan gas tank replacements and such, but nothing more than that. However, if you decide to opt for one of the best electrical tankless water heaters, you don’t need to worry about that either. Your bill may go down only up to 50% if it doesn’t run on gas, but that is still more than enough of a reason to obtain this appliance. We will cover all the types later in the tankless water heater reviews.​

Types of Water Heaters​

​Now, how to choose a hot water heater? which type of water heater is the best fit for you? 

In total, there are up to five different types of water heaters, all of which come with a tank and require pre-heating, except the tankless water heater:

1. Storage tank water heater

This is the most common type of water heater available on the market. Nearly every household still relies on them nowadays and they are hugely widespread. Like the name suggests, they consist of an insulated tank where water is heated and then stored until needed, thus I need to determine how big water heater do i need. The water emerges from a pipe on top of the water heater.

It also contains a temperature and pressure-relief valve, which is opened when either exceed a preset level.

The natural gas water heaters usually use less energy and cost less to operate(by about half) than electric water heaters, though you should take note that gas models are more expensive at the time of purchase.

2. Heat Pump (Hybrid) Water Heater

These water heaters capture heat from the air and transfer it to the water. They use up to 60 percent less energy than standard electric water heaters. While they do cost more than electric-only models, the installation is quite similar and the payback time is short. However, they do not work well in very cold climates and they need to be placed in an area that stays 40 to 90 degrees.

Because the heat pump is on top, in this case, a hybrid water heater needs clearance up to even 7 feet from floor to ceiling. Also, you will need about 1,000 cubic feet of uncooled space in order to capture enough heat from the air, including a nearby drain to discharge the condensate.

​3. Condensing Water Heater

Condensing water heaters are a viable option in the case where you are heating with gas and need a unit with a capacity of over 55 gallons. It is completely gas-fueled and doesn’t have a supply of its own, meaning it’s only useful for gas-heated homes.

These models are comprised of a tank like a conventional water heater, but that which captures exhaust gasses that would usually go out of the flue, which is considered energy waste. The gasses are induced through a coil in the base of the unit, where the incoming cold water is able to absorb most of the heat.

4. Solar Water Heater

This recent water heating solution contains a roof-mounted cell that absorbs the sun’s heat, before transferring it to a specific fluid with antifreeze similarities in a closed-loop system that runs toward the water tank. During the summer, these heaters allow for an enormous increase in savings, which makes them the most appropriate for warm and sunny regions. The savings tend to suffer in colder and cloudy weather, though, which makes it a quite restricted saving option. The majority of the models employ a backup system that starts up when necessary.

Even with local and federal rebates included, it will take an estimated 10 to 30 years to make up for the spent cash. While it is certainly the most futuristic and technologically advanced solution on the market, the potential buyers are advised to thoroughly consider spending that much money.

5. Tankless (On-Demand) Water Heater

Finally, the champion of this line of products is all about momentary usefulness, which is its main selling point. Instead of storing water, the tankless water heater uses heating coils to increase the water temperature as much as needed. They’re way more energy-efficient than a storage tank, but they provide a limited flow of hot water per minute, which is estimated to be 3.5 gallons on average.

They are optimal for those who normally aren’t drawing water for more than one use at a given time, such as running a dishwasher and a shower simultaneously. For any smaller household or a specific room in a large one, this product is ideal. It cuts the water heating costs down to a bare minimum and provides instantaneous heat.

The tankless models are best used at homes that draw on natural gas to heat the water. Certain electric models may require a pricy upgrade on the electrical capacity of the household, but the overall monthly costs are still largely reduced once this installment is executed.


Tankless and Tank Water Heater Reviews and Comparison

Just in case the above-mentioned explanations don’t quite relay the importance and innovative capabilities of the tankless water heater, we have devised a comparison of the fierce competitors in order to clarify all the differences to the furthest extent. To make this simple, we’ve decided to address the most important details of both tank and tankless water heaters and compare them:

Life Expectancy

First of all, every customer would like to know how long their not-so-cheap product will last before needing repairs or replacement. Now, those two are completely different things, but generally speaking about the timeframe between time of purchase and the time of complete and utter uselessness, they may differ.

Allegedly, every tankless water heater with a 12-15-year warranty lasts barely half that long. It is said that this happens due to the product not being on the market long enough for the customers to actually overrule this myth. This issue can also be attributed to the way in which the manufacturers treat the warranty. The users of this product require monthly maintenance service and it comes at no low cost either. However, the manufacturers that stands behind this statement like to clarify the evident difference in monthly costs even with this addition in mind.

On the other hand, tank water heaters are known to last for up to 15 years with few malfunctions. Their functionality tends to get impaired by the same issues that weigh the tankless water heaters down, but they are made in a way that lets them function with a number of issues. Most definitely, tank water heaters are cheap to maintain, but to what extent should one be prepared to go in order to avoid frequent servicing? Is paying a full water heating cost every month still worth it? It’s really up to the consumer to decide.

We can tell you only one thing for sure. As long as you don’t void your warranty, you don’t have to worry about anything. Word has it that this occurrence is too frequent, with all the rules that the manufacturers demand on complying to. Then again, the sheer number of customers tells a different story. Ultimately, it is still up to you to decide to take up this risk or to stick to your old tank.

Servicing

Both tankless and tank water heaters tend to encounter certain difficulties after a time of service. Of course, a tankless water heater won’t have any tank-related issues, but its set of intricate parts requires monthly monitoring and servicing. This claim is also backed by the fact that tankless water heater warranties usually cover the heater itself for 15 years, while the parts are only covered up to 5 at most.

​It’s difficult to weigh 5 years of lower bills versus eventual additional purchases in order to keep your tankless water heater going, but depending on how much you pay to keep your tank water heater running every month, it may well be worth it. Aside from part malfunctions, tankless water heaters tend to “lime up” where there is hard water, which may result in frequent pipe replacements. They need to be well-drained before a longer period of inactivity in colder climates, or the pipes may suffer significant frost-induced damage.

​Being the big brothers of tankless water heaters, tank water heaters require considerably less attention. They may run into issues like sediment buildup, but they’ve been proven to run smoothly even with a large portion inside, resulting in a minuscule 5% efficiency decrease in the worst conditions. Any sort of tank water heater maintenance is also sure to cost far less than any tankless water heater would subtract from your wallet. The repairs are cheaper, the parts are more available, it’s been on the market for decades upon decades, and it’s simply more reliable due to its development over the years.

​All in all, while the difference in servicing costs may be considerable, there is still a lot more that the tankless water heater puts on offer. Also, the great tankless water heaters mentioned on this list were manufactured with various improvements relating to this specific area. This is the factor you need to take into account before anything else when purchasing one, but if you decide it’s worth it, go right ahead.

​Energy Savings

​Of course, the main selling point of every tankless water heater out there is that it spends energy only when needed, which should significantly reduce energy consumption. This is the very reason behind their mass production and market popularity which has brought them to your web browser. Yet, how true is this claim in reality?

​Truth is, a lot of the computerized tankless water heater software constantly operates on electricity. Consequently, if you aren’t using it at a given time, that doesn’t mean it still isn’t spending valuable energy and racking up your bill. A way to go around this issue is to always completely turn off your tankless water heater or buy one with an automatic pilot light, that will shut down whenever it’s not in use. They do save power, but not as much as you’d expect, if not given proper treatment.

​Tank water heaters are well-known for spending considerable amounts of energy on a more than regular basis. The plethora of hot water that it offers needs constant heating to remain at the desired temperature, which unavoidably takes a large portion of electricity. One of the largest costs that a large household pays per month most often comes from sustaining their tank water heater. The amounts of money that consumers have to spend on this appliance eventually force them to opt for something as innovative as a tankless water heater.

​There is no contest in this category. Tank water heaters take so much energy to run that they can’t even be compared to a properly run tankless water heater, which is the absolute winner of this particular comparison.

​Pricing

​One of the weaker selling points of any reliable tankless water heater is the actual purchase cost, aside from any additional costs that may require coverage during its lifetime. The better it is, the more expensive it is, the more expensive it is, the more expensive the eventual part replacements are. This is the undeniable truth about tankless water heaters.

​One way to put this is that the purchase is more worth it the more you pay. Basically, if you have to pay a lot for it, it is more likely to be an outstanding tankless water heater. To put it simply, you require the same amount of energy to heat up the same amount of water, no matter how you do it. Now, condensing tankless water heaters can put their innovative technology to use and reduce this cost significantly, but their prices are situated in the high range.

​Tank water heaters come at a lower initial price, while they will take way more money on the long run. A cheap tank water heater may even come at a price four times lower than that of a viable best tankless water heater, but it’s sure to drain large amounts of bill money over the course of a few years. This is why tank water heaters are going out of fashion, at the pace of frequency of choosing to pay more first in order to pay less later.

​Therefore, it’s recommended to put together a calculation of yearly savings with a tankless water heater that you’re considering for purchase and a tank water heater that you already own and measure them up. If the amount of money that you will spend on maintaining your tank water heater is greater than that of the tankless water heater’s initial price, the calculation is clear. Whether to pay less now and way more over time or vice-versa is completely up to you, but the market speaks for itself.

Flexibility​

​When it comes to the multitude of services that tankless water heaters offer at the same time, as opposed to those that tank water heaters boast, it’s eventually down to a few key factors. The size of the object in which you will be using your water heater and a number of household occupants is a key factor. Both of these product variants have a recommendation, depending on the customer.

​Tankless water heaters usually don’t offer the option of heating water for more than two places at the same time. If you are taking a shower while your washing machine is running, be ready for some unavoidable heat fluctuation. However, there are some remarkable tankless water heaters that can rid you of this issue. This is why the tankless version is recommended for smaller homes and apartments, while even smaller living quarters such as cabins are an ideal place for their service.

Tank water heaters usually take care of the entire household at any given time, depending on their size and the amount of hot water stored. They were essentially made for this purpose, so they are mostly unchallenged by the performance of tankless water heaters when it comes to this section. However, dwellers of any smaller construction basically have no need to use them, as they tend to waste both space and money in these conditions.

​You should also keep in mind that certain tankless water heaters were specifically designed for colder or warmer climates. This essentially means that if you live in an area with extreme weather conditions, you’re way better off with the tankless variant. Those made for hot climates use the heat that’s abundant in the air to serve their purpose, while the ones designed for cold weather are much less likely to lose function in such conditions, as opposed to basic tank water heaters.

​Additional Issues

​The tankless water heater is a rather new product, and it will take the necessary time to perfect. Hence, it still faces certain problems that no tank water heater has had before. Although this may sound like a serious thing to consider, they are mostly trivial matters that are unavoidably included in the service of tankless water heaters.

​“The Cold Water Sandwich” is something that the newest tankless water heaters have overcome with state-of-the-art heating technology. Mainly, once the flow of water is halted, the water in the pipe will run cold, and that in front of the heater will trigger the heating again. This process causes a wave of cold water in between the hot, but it’s nothing to actually worry about anymore.

​While tank water heaters will instantly provide you with hot water once you rotate the red tap, the tankless version will let some cold water slip before the heating process overcomes the water temperature. This is also a problem of the past, which the tankless water heaters mentioned above have been rid of.

​Conclusion

​While it’s not a bad choice to stick to your old tank water heater, there are various advantages worth considering if you’d like to go tankless. From minimized monthly bill costs to on-demand heat and climate-related advantages, a great tankless water heater will take your water heating process to the next level, with numerous benefits, at a considerable price.

​Electric or Natural Gas Tankless Water Heaters?

​Once you opt for a reliable tankless water heater, you may be faced with the dilemma of which type is better, and why. Rest at ease, for we’ve prepared a thorough comparison of both variants available on the market. Let’s dig right into it, starting off with the most important factor:

Initial cost​

​When it comes to the initial product price, electric tankless water heaters have a significantly lower cost than their gas counterparts. Generally, whole house electric tankless water heaters cost somewhere around US$500-800, whereas gas tankless water heaters usually cost US$1,000 or more, especially if they encompass better quality equipment with electronic ignition systems. The installation costs are not included in the prices mentioned here (more on that below).

​Efficiency / Operational Cost

While gas tankless water heaters may be considerably more efficient than gas tank water heaters, their efficiency most often peaks at 80-85%. Inversely, most electric tankless water heaters peak at 98+% efficiency. Even though natural gas is usually a way cheaper input fuel than electricity per BTU of output power, this benefit is often outweighed by the higher efficiency of the electric tankless water heater, its longer service life, and cheaper installation.

To top it off, electric tankless water heaters cost much less than the majority of tankless gas models, assuming that you own the best electric hot water heater. What’s more, gas prices usually fluctuate more dramatically than electricity prices, while most economists agree that gas prices are now expected to rise substantially in the years to follow, whereas in most areas, the price of electricity should be relatively stable or at least on a much slower rise.

Installation​

​Gas tankless water heaters contain complex venting systems and have many combustion air supply requirements, especially if installed in a confined space. The existing gas lines and venting ducts are seldom usable. For the requirement of side wall venting, things can get even more complicated. Thanks to their high gas consumption, the existing ventilation systems rarely fit the norm. The bottom line is that these requirements may make installation quite expensive.

​Electric tankless water heaters often aren’t bulky, around one-third the size of a gas tankless water heater. According to their convenient size and the fact that they require no exhaust gas ventilation, they can be placed virtually anywhere not feasible to install a gas tankless water heater.

Consequently, electric tankless water heaters can usually be located closer to the actual usage point. They can be placed in a closet, in a crawl space, under a sink, or a wide variety of other areas where the traditional tank water heaters and gas tankless water heaters cannot. Unless an electric system upgrade is required, the installation of electric tankless water heaters is usually much cheaper than that of a gas tankless water heater.​

Warranty, Lifespan, and Maintenance

Electric tankless water heaters require little to no maintenance. In fact, aside from cleaning the inlet screen filter from time to time, electric tankless water heaters generally do not need any maintenance. On the other hand, gas tankless heaters need to be inspected annually by a skilled technician in order to ensure safe fuel combustion and performance.​

In the event of an issue, electric units are inherently easier to troubleshoot, diagnose and repair. The pure simplicity of their design means they have a much longer lifespan. Gas tankless water heaters possess very complex heat exchangers and fuel control, which are much more difficult to operate on in the field.

Energy Source Availability

The availability of adequate electric energy, propane or natural gas, can naturally affect the decisions as to which exact type of tankless water heater is best for your business or home. Electric tankless water heaters are sorted amongst very high power appliances. Since they heat water completely on demand, their top electricity needs are quite substantial, even though their total energy consumption is noticeably lower than traditional tank-type water heaters.

Accordingly, it is usually required that a home has a 200 AMP, 208 to 240V electrical service in order to run an electric tankless water heater (the smaller ones that are suitable for warmer climate areas can usually be installed on even 100, 125 or 150 AMP electrical services). Certain homes or business don’t possess such electrical power and upgrades can often be expensive.

On the other hand, the installation of a gas tankless water heater will almost certainly prove to be uneconomical if the building does not have an existing natural gas or propane service at its disposal, or if the diameter of the incoming gas line is insufficient (which is a common occurrence). You can also find the list of best gas water heaters 2015 and 2016 for more details.

​Water Usage Habits and Needs

​For a majority of homeowners and businesses, their water usage patterns and needs won’t affect their choice of what exact type of water heater they should opt for. Electric tankless water heaters have the ability to provide from 3 to 8 GPM of shower temperature water, depending on the model selected and climate.

​The said stats are often more than enough to please the needs of nearly any family, while gas tankless water heaters are there to live up to even the highest expectations. Generally speaking, a large amount of gas tankless water heaters on the market are capable of providing somewhere around 10GPM, which is sure to satisfy any consumer’s flow standards.

​Homeowner Preference

​Due to safety reasons, certain homeowners do not feel comfortable with using natural gas or propane to power any of their home appliances. In such situations, an electric tankless water heater is the optimal choice for peace of mind. Other homeowners tend to have preferences for one type for varying reasons, including the availability of energy (gas or electricity) in the event of a major regional catastrophe such as a natural disaster. Other users may still prefer one type over the other due to environmental reasons.

​The best electric tankless water heaters have extremely high energy efficiency, with more than up to 98% of the electric energy supplied to the units actually being used for water heating purposes. On the other hand, gas tankless water heaters usually have an energy factor lower than 85%, while they also contribute to greenhouse gas emissions.

​Ultimately, every homeowner should weigh their own needs against the pros and cons of both alternatives. In spite of that, the market reports an overall favorite when it comes to casual households. A majority of small and medium homeowners and apartment dwellers usually go for the electric type due to the high initial cost of gas systems (including installation), their maintenance requirements, inherent complexity and shorter lifespans and warranties.

​Installation costs

​It takes a considerable amount of money to get every great best tankless water heater installed and running, but once you’ve made the purchase, it’s something you must unavoidably complete. We will now address any of your existing installation cost concerns.

First of all, the consumers that hire a pundit to install their tankless water heater should expect to pay either a flat fee or an hourly fee. The total installation cost varies depending on the type of tankless water heater that is being installed and the professional who installs it.​

Factors such as installing proper ventilation in order to prevent carbon monoxide poisoning and a complete alteration of the size of gas lines and fittings tend to take an average of 10 hours. Consequently, the customers that decide to install a gas tankless water heater are bound to face significant costs.​

Electric tankless hot water heaters don’t take nearly as much time to install. The ones such as a point-of-use electric water heater can even be installed right under the sink by a plumber with some electrical skills. The electrical timer, electrical outlet, and water supply lines required for the installation of this type of water heater usually don’t have a high total cost. The average time that this specific product takes to install is a mere two hours, which allows for the consumers to pay significantly less.

Another factor that affects installation costs is a reduction offered on specific tankless gas hot water heaters. Consumers can make great use of a tax credit on products that qualify with Energy Star. Tankless water heaters with the Energy Star symbol are energy-efficient appliances that comply with the government standards. Such products are also highly rated in quality, features, and performance.

​Consumers will also need to pay for the material and labor costs for the other parts that are needed in the installation. The accessories required for a tankless water heater usually include a tankless gas connector kit, termination vent kit, the two-piece lead-free brass tankless water heater valve set, in conclusion with fittings and mounting hardware.

​Condensing vs Non-Condensing Tankless Water Heaters

​Since the heating process in any tankless water heater including the best tankless water heaters in the list above works through combustion, it is necessary to know the combustion differences between condensing and non-condensing tankless water heaters.

​During a typical combustion, the tankless water heater burns the hydrogen content of the fuel, resulting in the production of hot gasses. One of those gasses is steam or vapor. Once that steam is cooled, it turns into water that is generally referred to as condensation. The condensation water is acidic (3-5 pH value) and thus corrosive, meaning it will corrode steel metals and other materials.

​A non-condensing tankless water heater will push the hot gasses outside through a vent, where they will proceed to cool down. The released gasses have temperatures of around 300 degrees Fahrenheit and thus need to be vented through non-corrosive venting materials capable of withstanding the heat. If your tankless water heater isn’t made of stainless steel or doesn’t have stainless steel secured venting at least, you are welcome to purchase stainless steel category 3 venting or better, at a significant price.

​The gases ejected from the tankless water heater contain up to 20% of the actual energy that heats the water, meaning a whole fifth of the heat-generating capacity is wasted by being exhausted into the open. The hotter the exhaust gases are, the less energy goes into heating the water, which is why non-condensing units have an efficiency average of 80%.

​Condensing tankless water heaters extract the heat stolen by the gases and therefore exhaust cooler gases, typically around 100 degrees Fahrenheit. Since the exhaust gases are made much cooler by this technology, you can afford to use a cheaper venting variant, as it can then withstand the low heat emissions.

​By managing to capture the residual exhaust heat and transfer its energy to the heating process, units with this technology are known for their remarkable 98% top efficiency. A condensing tankless water heater may be more expensive than the rest, but it is well worth it, considering its increased performance and reduced costs of various parts.

​Final Verdict

​With all of the newfound knowledge in mind, you can now be certain of any decision you make when deciding which product from this list to opt for. We will now proceed with the final comparison and our own personal favorite.

​For a mountaineer or any high altitude and cool climate dweller, products 3 and 7 are most definitely the optimal choice, due to their high frost resistance and the ability to benefit from unfavorable temperatures. This is as far as we will recommend them, due to the finer qualifications of the other 5 products when other climate types are in question.

​Products 2 and 5 are ideal for any apartment or small household, perfect for heating one room at a time. Product 2 runs on gas, while product 5 requires electricity. Both types will induce certain costs to run and set up, but they average out at about the same amount, while they are both very cheap and the most economical choices on this list.

​Products 4 and 6 both run on gas, take a considerable amount of money to install and they are the most expensive choices on this list. Regardless, these two products are the best large household heaters on the market with irreplaceable qualities. We would recommend nothing but these two products for the heating purposes of any spatial home or building.

​Finally, product 1 can take up the roles of almost all of its competitors, due to its Advanced Flow Control technology that none of the other products can offer. This perk allows it to cost significantly less than any large-area tankless water heater, while still performing its duty with prime quality. As it belongs to the mid price range in comparison to the other products on the list, and yet just as effective as any of them, we consider it to be an outstanding tankless water heater.

​Every passing day, significant amounts of homeowners decide to opt for a tankless water heater as a result of the realization of its benefits. It can be quite bothersome to try and find the finest available choice on your own, but we’ve hopefully ridden you of that issue.
