How to Turn Up Hot Water Heater

Plain old tap water can be dangerous - literally millions and millions of bacteria are just waiting around to invade your body through infected water supplies. This is one of the contributors to the rise of the gas, electric and durable tankless water heaters.

They solve loads of problems, sure, but it doesn't fool proof - water heaters set too high send thousands to hospitals each year with burns and put you at the risk of various unique types of infection (for instance, Legionnaires ‘disease kind of like the reverse of normal pneumonia).

Safety experts recommend a temperature setting of 120 degrees F - this is neither too hot nor too cold for home use. The only drawback is finding that setting on the dial since it isn't exactly easy because most deals aren't labeled with numbers in the first place.

How to turn up hot water heater on an electric water heater!

Now, knowing that most durable tankless water heaters and electric water heaters are used in saunas, it might be worthwhile to note that it’s pretty easy to get one through some of the best infrared sauna reviews on the internet.​

Otherwise, here are the necessary steps needed to know how to turn up hot water heater on an electric heater.

  • Turn off the circuit breaker for your electric water heater at the electrical box. Most, if not all, electric water heaters use around 240 Volts of electricity, meaning they have two circuit breakers that are to be switched on and off together. If it’s not listed on the location sheet on the inside of the panel, be on the safe side and turn off all the power.
  • Carefully remove the insulation from the thermostat by turning it with a flathead screwdriver.
  • Depending on what kind of heater you own, there may be both an upper and a lower heating unit. In which case, there should be two thermostats behind two different panels. Turn this knob with a flathead screwdriver to either raise or lower the temperature.
  • Remove the access panel to the water heater with a screwdriver and set one or both heating units to the same temperature using a flathead screwdriver. It’s strongly suggested that you note both the beginning temperature and adjusted temperature then check the tap temperature at the faucet farthest from the heater.
  • Make adjustments until the desired tap temperature, in most cases, including this one, to 120 degrees, is reached.
  • Replace insulation and the access panel.
  • Turn the circuit breaker on.
  • Let the water in your hot water heater settle to the new temperature and check on it after 24 hours from the faucet farthest from your hot water heater, preferably with a meat thermometer. It should read around 120 degrees Fahrenheit. If it is hotter or colder than necessary, go back to Step 1 and make the necessary readjustments.

That’s it for the electric water heater folks - have fun with your durable tankless water heater and don’t forget to check out the best infrared sauna reviews. Who knows, you might find a new hobby.

To all the gas water heater people, nobody’s forgotten about you.

How to Turn up Hot Water Heater Temperature in Gas Heater

Before you get started, make sure you know how to relight the pilot in your gas hot water heater. Of course, your best option is to consult your owner's' manual. If it’s inconveniently lost, here is a general run-down for changing or adjusting your hot water heater's temperature.

Before we begin, a quick precaution:

  • Remember; don’t use any kind of flames near any of your gas appliances. Any kind of open flame is generally unsafe for use near your gas water heater - do not use candles for lighting or smoke near it.

Here is a quick guide on how to turn up hot water heater if you have a gas heater:

  • Figure out where the gas valve and temperature adjustment dial are on your gas water heater.
  • Slowly turn the adjustment dial to change the temperature to the desired range. Different models have different default settings, some with the Vacation, Warm and hot setting in different configurations. Other models have approximate degrees like “A, B, C, D, E” or “1, 2, 3, 4, 5” instead of the markings on this dial.
  • Turn the dial so that the temperature setting lines up with the mark at the top of the control.


There you go, that’s pretty much how to turn up hot water heater on both electric and gas heaters. It’s a simple process that requires caution along the way, but overall, nothing too challenging.

If you have problems along the way, consider getting a durable tankless water heater to save yourself the hassle of maintenance and later head over to the best infrared sauna reviews and get yourself a treat.

Water Heater Leaks From Drain Valve

It’s nothing new that a water heater drain valve can start leaking and give you problems that can be pretty troublesome to deal with. Sometimes it’s the valve itself that’s leaking, or in older tanks like those for your home steam shower, it could be the flange around the valve that leaks.

There are three basic ways of fixing water heater leaks from the drain valve or flange valve:

  • Tightening the valve
  • Capping the valve outlet
  • Replacing the drain valve. However, this should only come down as the last resort because it’s a pretty big job to handle on your own. Preferably, you should call a plumber if there’s no other alternative.

This article should give you a proper rundown of what to do if your water heater leaks from drain valve and how to fix it.

What’s the Drain Valve for, anyway?

First things first, of course, you have to understand why the drain valve is necessary. The purpose of the drain valve is, as its name suggests, drain the hot water heater. Certain repairs that you might need to do on the water heater can only be achieved if you drain the tank. This is especially so if you are the proud owner of an electric water heater.

The other reason here exists is to perform routine maintenance on the water heater. Hot water tanks should be flushed out periodically so you can remove sediment that builds up at the bottom of the tank, effectively making the tank lose its efficiency. The drain valve is used for flushing the tank.

Problems with Drain Valves

Drain valves that come straight from the factory are plastic and thus, aren’t very durable. You can flush it out and tighten it - a simple fix for a simple problem.

The second option is to replace the drain valve altogether. Doesn’t seem like too big a job, does it? All you have to do is to drain the tank to change it, right? Basically, yeah, but it may end up being a lot more work than it seems in the long run.

If the leak is really bad, you have no option but to replace the drain valve. This is, of course, the less fun, more involving option. On top of that, most factories installed drain valves are plastic and break easily, so anything could happen along the way.

Too many problems? If your water heater leaks from drain valve constantly and you don’t want to have to deal with it every day, you could alternatively look out for cool tankless water heater reviews. Tankless heaters have great advantages over conventional heater tanks.

Fixing a Water Heater Drain Valve

First, you’ll need a replacement water heater drain valve, which you can easily get online or at a hardware store. The most common size is 3/4-inch.

Fixing a Water Heater Drain Valve


Unless you empty the water heater first, replacing a drain valve raises the possibility of flooding your basement unless, of course, there’s a floor drain nearby. In most cases, it involves having someone help you and use buckets to collect and dump water that pours from the water heater while you’re replacing the valve.

  • Shut off the valve on the cold water supply pipe that fills the water heater so it won’trefill as you drain its contents.
  • Turn off the circuit breaker of the electric water heater or the gas valve of a gas water heater so the water doesn’t reheat. Use hot water at faucets and tubs in the house as long as it’s available. Allow the water in the water heater to cool down to a safe temperature—this may take some time, maybe even a full day.
  • Using a pipe wrench, unscrew the valve from the tank by turning it counterclockwise. The further it loosens, the more it leaks, then sprays, and eventually pour warm (or hot) water, so be careful. Remove the valve entirely.
  • If mineral deposits are in abundance inside the tank, they may block the drain hole as the water pours out. Use a screwdriver to break-up deposits. However, if the deposits are severe, you’ll need to drain the entire tank this way.
  • When the water begins to run clear of the mineral deposits, insert the new drain valve in the hole and screw it in until it is snug, pointing down, and isn’t leaking.
  • Open and close the new drain valve to test it then shut off the drain valve. If you opened the water heater’s pressure-release valve or a hot water faucet at any point, close those, too. Finally, open the water supply valve and let the tank refill.
  • Turn the circuit breaker back on if you have an electric water heater or in the case of a gas heater, open the gas valve and relight the pilot to restart a gas water heater, as per the water heater’s instructions.

How to Fix a Leaky Hot Water Heater Pressure Relief Valve- Know it

What is a Temperature Relief Valve?

When water is heated, it evaporates and turns into steam. Keep heating this steam and it will also expand and look for somewhere to escape from. Pressure builds up and due to the resulting force, managing to break through is so powerful it would literally be able to blow up inside the house with the force of a missile (steam will manage to break through nearly anything, if not kept in check, even steel). Obviously, nobody wants their house blown up and water tank production companies could be suffering millions of losses in damages daily, which they also don’t want.

What is a Temperature Relief Valve


In comes the little guy. The temperature and pressure relief valve (the TPR valve), often called the temperature and pressure valve (T&P valve) is a water heater safety device designed to relieve the pressure from water heaters in case of an extreme temperature/pressure rise (anything above 150 psi, is explosive, if you’re curious). As you can guess, it’s pretty important that the T&P valve works properly, and in perfect correspondence with the water heater thermostat.

Enter your text here...

Why is water leaking out of the temperature relief valve?

Now that you realize its importance, we finally come down to the million dollar question (actually, it will cost like fifteen dollars to fix, but you get the idea). The first thing you should keep in mind is that most times, the source of the problem is usually with the temperature pressure valve itself, especially if you happen to own a hot water heater with an old relief valve.

As before stated, one reason temperature pressure relief valves will release water slowly if there's too much pressure in the tank, but this only happens in closed water systems. If you’ve got a leak, it won’t work properly.

The other possible reason could be that the water-pressure regulator valve may also be broken.

It’s recommended that you periodically test the temperature pressure relief valve by lifting its lever to make sure it is working - if it is, hot water should come out of the discharge pipe and when you release the lever, it should snap back down. Doing this with a broken or old valve can cause it to leak—if it does, you’ll need to replace it.

Why is the relief valve releasing large amounts of water?

This is a normal occurrence that happens when the valve is opened because of high temperatures. To fix this, you first have to check the value on the temperature pressure valve.

How to check a TPR valve

  • In order to check for a leaking valve, feel the drain line with your hand to see if it’s too hot. The drain line may be a little warm near the valve, this is completely normal. If the line is hot, the relief valve is opening.
  • Raise the test lever on the relief valve where you should hear water discharging out of the relief valve drain line. If you do, then no worries, your valve is working properly. If you don’t hear a discharge sound or your test lever won't raise (don't force it), you’ll need to replace the relief valve as soon as possible.

How to replace a water heater temperature pressure relief valve

  • Depending on the kind of heater you have, either turn the water heater breaker off for an electric heater or set the temperature to the lowest setting on a gas water heater.
  • Turn the control knob to the factory pilot setting.
  • Turn the water supply off at the water heater.
  • Turn on the nearest hot water faucet to relieve the pressure on the tank. If the pressure relief valve is mounted on the side of the tank, you have to drain the tank until the water level is below the valve. If the relief valve is mounted on top of the tank you’re okay to proceed.
  • Remove the drain line that's attached to the relief valve.
  • Cut the line and unscrew it from the relief valve.
  • Remove valve with an adjustable wrench and tap the end of the wrench with a hammer to loosen the valve.
  • Lift temperature pressure relief valve from water heater.
  • Remove the old relief valve and using teflon tape or pipe dope, install the new relief valve.
  • Reinstall the valve drain line, and if your drain line is a CPVC pipe be sure to use CPVC glue to couple the line back together. Give the glue 2 hours to dry before testing the new relief valve.
  • Refill the water heater. Leave the hot water faucet open until all the air is out of the line.
  • Check for leaks, and if it’s working just fine, turn the power on for an electric water heater or for a gas water heater, set the control knob back to the on position.
  • Turn the temperature control knob to the normal setting.

That being said, you should have a fully functional hot water heater pressure relief valve, but if the problems persist, why not check out some tankless water heater reviews online and get yourself one? They’re much more efficient, affordable and require less maintenance than any gas or electric water heater.

How to Reset a Water Heater-Useful Tips and Information

Why Does Your Electric Water Heater Reset Button Keep Tripping?

Electric water heaters are far from perfect, and couple this together with the kinds of temperatures the water is expected to reach, and you may well have a catastrophe on your hands.

One of the most common problems electric water heater owners face is the reset button constantly popping out and needing to be reset. To get straight to the point, the most likely problem is that the water in your water heater is getting too hot. Don’t worry, though, the design was intentional and it’s meant to do this.

The water heater limit switch is a built-in safety device designed to shut the power to the water heater down if something malfunctions and the water gets way too hot. Sometimes the water temperature in your heater reaches or exceeds 356 degrees Fahrenheit. In such a case, little red button located in the centre of the limit switch, just above the water heater thermostat (called the reset button or the high-limit switch) trips. If this happens, the limit switch can be reset by pushing the red button after the water cools down.

This is for your own protection - essentially preventing you from getting scalded or getting burned when using the hot water in your home. Imagine turning on the shower and meeting superheated water on your back.

Great, you now know what causes the red button to trip, but not how to reset a water heater, nor what causes it to overheat in the first place because that’s definitely not meant to happen. So, what’s causing the water in your heater to get so hot? Once again, the most likely cause is a broken thermostat.

The Bad Thermostat

Most electric water heaters have a lower and upper thermostat. These thermostats are responsible for controlling their own individual heating elements and your key to how to reset a water heater.

When the previously heated water has cooled off, the thermostats kick on the two heating elements to heat the water, and once the water has reached the desired temperature, both thermostats shut off the heating elements.

However, they are a human invention and far from perfect, they can easily get wrecked, and when they do, they could get stuck in the “on” position. This basically means that that the heating element will continue to gradually heat your water until it causes the high-limit switch to trip.

How to Fix the Broken Thermostat

If this happens to be the problem, your case of how to fix a water heater is replacing the thermostat altogether. A qualified plumber would use a multimeter to test the thermostats and find out which one is bad and fix it for you.

Alternatively, you can do this yourself - checking a water heater limit switch a multimeter isn’t too hard a task. You can easily achieve this through the following steps:

  • First, turn the power off to the water heater.
  • Set your multimeter to a setting of rx1.
  • Put one probe on the first terminal and one probe on the second terminal.
  • On an analog meter, the needle should normally sweep all down to zero. If this happens, the limit is not tripped, and the thermostat is likely not the cause of your problem. However, if it does, you should either call a plumber immediately or replace the thermostat.

If the problems persist past your perseverance point, why not head over online and have a quick look at some of the best tankless water heater reviews?

Other problems That Could Cause the Switch to Trip

Nine out of ten times a bad thermostat is the reason your water heater’s reset button trips, but it’s by far not the only one. If you tested the thermostat yourself and found it wasn’t the cause of the problem, you can explore some of the following options and hopefully find a solution to your problem.

Some of the most common reasons for the switch tripping include:


A shorted heating element

Your thermostat may be working just fine, but continually shuts off the heating element, and this short in the element causes it to continue to heat your water. This eventually leads to the water to overheat.


Loose wiring

A loose wire in the water heater can also generate a lot of heat that can consequently cause the high-limit switch to trip.


Broken high-limit switch

If the thermostat isn’t the problem, perhaps the switch itself is malfunctioning and tripping when it shouldn’t be.

In all the above cases, your safest bet to how to reset a water heater is to call an electrician and have him looks around for loose wires. However, tankless water heaters happen to be more efficient, heat faster and cost less than their competitor tank heaters. The best tankless water heater reviews can attest to that.

How long does it take to drain a Water Heater?

There are countless reasons why you’d want to empty your water tank - basic maintenance or even a full replacement of the tank to name a few.

The maintenance part especially comes into play when the water is hard. Hard water is simply water that contains lots of minerals, sand or other dissolved solids in the water. Over time, these sediments settle at the bottom and around the walls of the tank. In both gas & electric water heaters, this has two major implications:

  • If the sediments build up, it will block clog the drain, making it impossible to drain the water.
  • It can result in prevention of heat from reaching the water, basically implying the water won’t be able to be warmed (or heated) anymore.

Instructions regarding how long does take to drain a water heater may depend on the type of water heater you have, but luckily enough, here are detailed steps regarding each type of heater.

If you’d like to save yourself the trouble, why not check out some tankless water heater reviews and infrared sauna reviews and find out if they fit your taste.


Step 1: Cutting off the Supply

When trying to figure out how long does it take to drain a water heater, you first have to figure out how to empty the tank. This step varies from a heater to heater.

  • Electric Water Heater: Turn the power off to your electric water heater then tape the breaker at the off position. If you were lucky enough, your builder, electrician or plumber may have been nice enough to install an actual outlet, so all you need to do is unplug it.If you don’t shut off the power and end up exposing the heating element(s) you will more than likely burn them out.
  • Gas Water Heater: There are basic two trains of thought here: some argue that you only need to turn the gas off, while others say that turning it to pilot is a more than adequate option. This is up to you and either one will work fine.

Step 2: Turn off the cold water supply to the tank

This step should be simple enough to figure out. Most times, the valve for turning the cold water supply off it found next to the ‘on’ switch off the heater. Tankless water heater reviews are a good place to avoid the hassle, though since they don’t work on a ‘store water’ basis.


Step 3: Attach a garden hose to the drain valve

Attach a garden hose to the drain valve


The drain valve is usually found at the bottom of the tank. Find a reliable, good quality garden hose and attach it to the bottom of your hose.

Follow few quick tips to see how long it takes to drain a water heater. Cheap hoses tend to turn soft and are prone to leakages when hot water is run through them. This is often the case for people who fail to check infrared sauna reviews before actually buying them.

Just be sure to run the hose to a convenient drain and not simply into your crawl space. If it happens you don’t have a drain or it happens to be in a higher position than the water heater, you can always do the bucket brigade or alternatively buy a pump to help propel the water out and of the house.


Step 4: Draining the water

  • The first step is to open up your hot water faucet, then the drain valve on your water heater. After you’ve done this, you should open up the hot water side of any faucet.
  • Second, open up the drain valve on the tank and allow it to flow empty.
  • Depending on the size of the hose and the water pressure, it should deliver 9 to 17 GPM. If you have a 50-gallon tank, the water should be flowing at full pressure for 3 to 6 minutes. If the water flow is slow, turn on the cold water supply to the tank. This should hopefully help you blast through the clog.

Step 5: Rinse and Repeat

  • After, you’re done waiting out and the tank is finally empty shut off the drain valve.
  • Turn the cold water supply back on and let the water heater refill. Once the tank is partially filled, about ½ full, let the tank fill partially and start the draining process again.
  • Once the water starts flowing out, turn the water supply off. If you have extreme amounts of sediment still in the tank, you may have to repeat this procedure a few more times. If the drain water is running clear, you are done.

A few final notes

For the most part, you are pretty much done. So, how long does it take to drain a water heater? About 20 - 30 minutes, depending on the size of your tank.

An easier alternative would be to see what people’s thoughts in a few tankless water heater reviews and see how it goes for you. Before you buckle up and start filling that infrared sauna with your now hot water, feel free to ask around for the best infrared sauna reviews, you won’t be disappointed.

Tips on Rinnai tankless water heater problems



When it comes to installation you made need a professional to do it. This is one of the Rinnai tankless water heater problems. It is important to get a certified installer which means an extra cost. However, you would not want to damage your water heating system even before you start using it. In the long run, it will save you a lot of costs.


Time to get hot water

In some instances, according to steam shower generator reviews it takes some time to have some hot water running. This, however, depends on how far your point of use is. For most people, there is no wait time in getting hot water. It is recommended that you have the tankless water heating system closer to where you are using it.


LC code

It is easy to often see the LC code due to hard water and calcium issues. It is advisable to flush the unit regularly or have a water treatment system in place.



Rinnai heating products are expensive. However, they will save you much more than you will spend to purchase.

How to use Rinnai tankless water heater

  • Switch on the dishwasher, shower or washing machine. Cold water will enter from the inlet pipe at the bottom signaling the PC board to activate ignition.
  • The combustion fan will turn, allowing oxygen into the burner for ignition as the gas the gas valve opens up slowly. The igniter will stop sparking when there is an adequate flame. This begins the net series of operation which happens in seconds.
  • 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.

Important to Remember

Rinnai tankless water


  • To ensure that your Rinnai tankless water heater runs smoothly flush the unit regularly to keep it free of lime and scale. The in-line screen filter located on the inlet fixture should also be checked periodically for filters.
  • Remember to switch off the incoming water as you do the check. It is also important to always ensure that there are water, gas, and electricity to the Rinnai water heater.
  • Remember to always get a certified installer to attend to any Rinnai tankless water heater problems.

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.


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.


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.


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.


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.


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.


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.
