  • As the water passes through the copper heat exchanger coils it is heated. It goes out through the outlet pipe (hot water) to where hot water is needed. If you are using a condensing model, the water is preheated as it goes through the latent heat exchanger, capturing any additional heat before it gets into the vent system
  • The blower and gas valve automatically adjust oxygen and incoming gas to attain the water heating demands. When the demand is great, the flame expands over the width of the burner thus heating more water. When the demand is less, the water heater uses less gas and a smaller flame. The digital controller lets you choose your preferred temperature and the tankless water heater will always adjust to ensure the set temperature is maintained.
  • When the hot water fixture shuts, cold water no longer gets into the tankless water heater, thus the flame reduces. The combustion fan continues to run at a low speed for a short span of time allowing the exhaust of any combustion gasses that might have been left in the system.

  • 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.

  • Once again, this depends on your Noritz tankless water heater model. If you have one that has an external recirculation mode, the most viable method of fixing your problem is to have a contractor install you a recirculation return line. 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.

Should I Turn Off Water Heater if Water is Off?

Should I turn off water Heater if water is off? This is perhaps one of the most commonly asked questions on the internet, and, as is often the case with questions asked on the internet, it’s at the same time, one of the most ill-advised.

Should I turn off water heater if water is off? Honestly, the true answer is it depends on some scenarios. There are a wide variety of scenarios where either answer would suffice, but there isn’t one simple answer to this. First of all, considering the fact that the water heater itself, especially high quality tankless water heater, was designed to be as accident-free as possible.

When You Should Turn the Heater Off

  • The first scenario is the most obvious one, and it’s not merely advice to help you keep safe. This comes about when, for instance, your water tank is empty and you’re leaving for an extended period of time. Most water heaters usually divided into two, separating the cold and hot water.
  • They also have a dip tube on the cold water side that keeps the cold water at the bottom of the tank. If anything happens and pressure is lost on the cold water side, the tank siphons down through the cold water inlet until it reaches the bottom of the dip tube. Then, considering there's no more water in the tank to absorb this heat, the dip tube may melt and the tank will end up getting be damaged.
  • However, this is a very unlikely scenario, since it depends on the absence of water from your tank, which, in itself is completely unlikely. You’d have to intentionally cut off the supply from the water tank, or otherwise, be experiencing serious water shortages for this to over come into play. Should I turn off water heater if water is off? In the scenario your water tank is empty or significantly lacking water, the answer simple answer is yes.

When it really doesn’t matter to turn it off

  • If my water tank significantly is full, should I turn off water heater if water is off? Most people ask, If my water heater is left on, and the water supply is shut off, will any damage occur to the gas fired water heater, if very little of the hot water won’t be used much, or not at all?
  • Well, if you won’t be using the water for some time, and the water will only be off for a short time there is little to no risk involved. You can also shut off the cold feed valve just to ensure no water is siphoned out of the tank if cold water is also used with the tank off.

This would, however, not allow much of the hot water to be used out of the tank as this will have now air locked the system. You need to note, however, that the water heater will still turn on and off to maintain the water temperature inside of the tank, anyway.

Think about what would happen if you ever go away for a prolonged period of time. In most circumstances, there will be no water use for days, maybe even weeks and this doesn’t cause any problems with the tank. Even if someone does use water from the tank most (if not all) modern water heaters have low water cutoffs normally built into the unitroll (or aquastat).

Now, your tank has a dip tube for the inlet. This dip tube, according to standard specifications, stops 4 to 8 inches above the unitroll (this basically regulates temperature water inside the tank). It ensures that for whatever reason if the cold supply happens to lose pressure, the water isn’t siphoned out of the tank completely.

This design is meant to avoid the tank from being "tricked" to continuously running in order to try and maintain temperature if all of the hot water in the tank is used up. This also helps avoid the possibility of a melting dip tube or a catastrophic failure of the tank.

  • Should I turn off water heater if water is off? Don’t worry. The fabulous design already did your job for you. You don’t have anything to worry about.

Should I Turn Off Water Heater if Water is Off? The final answer

  • To be honest, and completely realistic, there is no danger involved in having the tank on with the water off, especially since the tank works through water pressure in order to supply the hot water and the tank pressure will be equal to your water pressure the whole time - if there’s no inlet water pressure, there will be no resultant outlet water pressure.
  • Besides, if shutting off your water and leaving your water heater on even happens to cause damage or catastrophic failure, then the water heater manufacturers would be up to their necks in lawsuits every day. That’s the whole point of engineering, really. Even if it did cause any issues, all the parts of the machine, including the labor provision and costs, would be covered by the manufacturer.
  • So, should I turn off water heater if water is off? At this point, it’s hard to say anymore. Depending on your situation, you should or you shouldn’t.

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.

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!

Water Heater Expansion Tank Installation

All the water supplied in homes is usually contained in a centralized underwater tank. From there, the water is then distributed to homes all over the neighboring regions. However, basic physics tells you that when water is heated, it expands, as mentioned in Rheem tankless water heater reviews.

Normally, in older homes, the expanded water used to push back into the water main or the individual homes themselves, causing a backflow of pressure.

However, most homes today have backflow prevention valves which stop the water in your home from reentering into the water supply. These valves can be placed inside water softeners, in the pressure regulating valves or on the water meter itself.

Once again, the expanded water now has nowhere to go and the water pressure in the house's pipes can increase dramatically, most times to the point where the pressure valve discharge pipe starts dripping.

What’s a Hot Water Expansion Tank?


This is where the thermal expansion tank comes in. It has an internal air bladder which absorbs the expanded water and protects your precious plumbing, appliances and the water heater. For basically these reasons, most homes now need a thermal expansion tank (and, most times, a properly adjusted pressure regulating valve). In fact, not having a thermal expansion tank is the most common reason for a dripping discharge pipe.

The water heater expansion tank installation usually happens close to a water heater and may be installed in any orientation. Internally, there’s a flexible diaphragm which divides the tank in two - the “wet” side, which creates a connection to the plumbing system and a “dry” side, which features a valve that allows the pressure of the tank to be adjusted as needed.

Water heater expansion tank installation – How to do it?

Nine out of ten times, the water heater expansion tank installation is done on the cold water supply of a domestic hot water tank, since here is where it’s’ most effective. The process itself is fairly easy and usually only requires a tee fitting to be added to the water line. Here are a few factors you need to consider first.

The Positioning

The first thing you have to do is decide where you want to install the water heater expansion tank. Obviously, the tank has to be installed between the cold water shut off and the water heater inlet, but you still have to decide where the tank itself will sit.

The Orientation

Most tanks will work regardless of the orientation. However, some orientations hold their own advantages. For instance, a tank installed vertically with the air side up and the tank’s bladder ever happens to fail, the tank may continue to function (albeit at a reduced capacity) until all the air escapes from the tank.

However, if the tank is installed with the air side down and the bladder unfortunately fails, all the air will immediately move to the top of the tank, and the tank will fill completely with water.

The actual process- Installing the water heater expansion tank

Now that you’ve decided where the tank will connect to the plumbing system, also being where the tank will spend the rest of its life, it’s time to start the actual installation of the water heater expansion tank.

1

Turn off the water

First things first, you have to figure out how to turn off the water heater, and then turn it off. Afterward, you’ll have to locate the cold water supply shutoff valve and turn the valve to off position. Finally, turn on the lowest hot water tap in the house. This will release any built up pressure, also preventing water from spraying out when you cut the pipe in the next step.


2

Mark and cut the pipe

Using the tee as a guide, mark the pipe where you’re going to install the tee then cut the pipe at the positions you’ve marked using a pipe cutter.

If you don’t have to cut the pipe, it’s safe to skip this step.


3

Install the tee

Solder, snap, or twist the tee into place and then install any extension pipes required to reach the tank’s final resting place.


4

Check the system pressure

At this point, you’ll want to close the faucet and open the shutoff valves. Turn on all the hot water fixtures in the house until water flows normally to ensure the system is filled and is at full pressure. Check for any leaks and repair them.

Attach a pressure gauge to any part of your plumbing and open the valve to get a reading. If the pressure is not within the normal range of 40 – 80 psi, you’ll have to take steps to correct it.


5

Pre-pressurize the tank

Almost all water heater expansion tanks come pressurized from the range of 12 – 40 psi, but before you install the tank you’ll have to match the system pressure. Start off by removing the protective cover from the air valve on the tank.

You can use a tire gauge to check the pressure and a bicycle pump, or compressor, to fill the tank and match the system pressure of the tank.


6

Mount the tank

Once you’re done, attach the tank to the plumbing, and mount it using your straps and/or brackets. Turn everything on, and then check for any leaks.


You’re pretty much done, so stand back and revel in your success. You know about the water heater expansion tank installation and you can tell others about it.

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.
