A tankless water heater provides many benefits over the traditional storage-based system. Instead of heating water in advance and then store it for later use, the instant system only heats the water on demand. Besides costs and energy savings, tankless water heaters are easy to install and maintain. Although they provide energy and water savings, you can optimize the temperature to improve safety and reduce your bills further. In particular, lowering the temperature will save energy and reduce water usage without sacrificing comfort.

Why change the water heater temperature

While you may need certain temperatures for some applications, the heat may be inadequate or uncomfortable for others. Usually, tankless water heaters have a default temperature setting of 140 degrees Fahrenheit. However, this may be too hot for some users and especially the children and elderly. Even for young and middle-aged people, the hot water may burn or scald them.

Usually, the safe and comfortable temperature is 120 o F or 50 o C but you can still set it to a lower value depending on your preference. Some heaters incorporate anti-scald devices or thermostatic mix valves that regulate the temperatures and ensure that it reaches the point of use, such as the showerhead or sink at a constant and safe 120 o F or 50 o C. However, these will only improve safety but do not provide much energy savings since they will cool the water near the outlet.

When a unit serves many applications such as showering, dishwashing, laundry, and more, you may need to install it in the most appropriate place and then run pipes to the application area. As the water flows through the piping, it will lose some heat to the surrounding and reach the sink or showerhead at a lower temperature. 

In particular, using uninsulated metal pipes over long distances will lead to significant losses. In such cases, you may consider adjusting to a higher temperature to compensate for the losses. However, this will result in more energy use and bills.

That said, although you have the liberty to set your temperature at the maximum figure, you may need to consider other issues such as safety, especially if other people are using the same shower or water to do dishes and other activities. You also need to note that the higher the temperature, the higher the energy you require for heating your water.

Advantages of low-temperature settings on a tankless water heater

Benefits of adjusting the temperature of a tankless water heater include improving safety by preventing scalds and burns and reducing your energy and water bills. 

Saving energy

If you set your temperature too high, you will require more energy to heat the water. And this means higher energy bills at the end of the month. In a typical setting, reducing the temperatures by 10 degrees results in 5% energy bill savings, and you can realize 10% savings if you reduce by 20 degrees. However, this may vary depending on the heater model and efficiency. Besides the savings, using less energy reduces environmental degradation.

Improved safety 

The default temperature setting for a new tankless water heater is usually 140 o F or 60 o C. Generally, showering with such hot water can burn or scald you seriously. In particular, the temperature is too high for the elderly since they may take time to sense the excess heat. Similarly, children are at risk due to their delicate skins. In either case, the hot water may lead to scalding or burns. 

Saving water

If you heat to higher and dangerous or uncomfortable temperatures, you need to mix with more cold water to make it comfortable and reduce the risk of burns. As such, you end up using more water, unlike if you had just heated it to a lower and more comfortable temperature.

Checking your hot water temperature

If you do not know your current water temperature setting of the tankless water heater, check the LCD, if any, or at the dial position for some models. Alternatively, use a thermometer to manually check the water temperature at the outlet of the shower, sink, or other application areas. First, turn on the water heater, let it run for a few minutes, and then take the reading.

While you can rely on the tankless water heater thermostat to maintain the temperature at your desired value, you can check it manually at the outlet. Losses and other factors may cause temperature changes between the heater and point of use. You should then adjust the settings to compensate for the losses and ensure that you achieve the desired output that is comfortable and cost-effective.

How to adjust the tankless electric water heater temperature

Most tankless water heaters provide a flexible temperature range to suit different applications and preferences. For example, if you want to shower with scalding hot water, you can set your temperature at the maximum setting, which is about 140 o or 150 o F for most units. However, for most people, a 120 o F or 50 o C setting provides a comfortable and safe temperature for showering. 

In practice, tankless water heating systems have adjustable temperature settings. However, the accuracy and method of adjusting may vary from one model to the other. As such, you need to establish your system and how to change the settings, usually available from the user’s manual.

For tankless water heaters with an LED panel and control, adjust the temperature while checking the water to ensure that you get the right setting. For some models, you may need to use dial control. Once you set a temperature, an inbuilt thermostat monitors the water as it gets hot. Upon reaching the set temperature, the thermostat cuts off the power to the heating element. It then continues monitoring the water and powering the heating element, on and off, to maintain the water at the set temperature.

As mentioned earlier, you may consider using a thermometer to ensure that your water is at the right temperature at the point of use. Alternatively, feel the water on your skin and, if possible, ask all the other users to check so that you can adjust the temperature to a safe setting for everyone.

In a home where one tankless electric water heater serves multiple applications such as dishwashing, laundry, and shower, you will set the temperature once. However, if you have different tankless heaters around the house, each for its specific application, you need to adjust the temperature individually to suit the application.

Thermostatic mixing valve

Another approach to ensure that the water reaches the shower or other application area at the desired temperature is to use a thermostatic mixing valve. It automatically mixes the right amount of hot and cold water to provide the set temperature while responding to fluctuation in the pressure or other factors. The add-on device, installed near the hot water outlet, controls temperature hence improving safety and comfort.

Remote temperature control

With most modern tankless water heaters, you can add digital technologies that would allow you to control them remotely. For these models, you can connect them to the internet using Wi-Fi or other communication technologies. Adding connectivity enables you to adjust the water temperature using your phone or tablet. It also gives you the ability to monitor the usage of hot water, electricity, or gas remotely. For example, the solution allows you to turn off your heater remotely from anywhere, even when you are not at home.

Temperature control via smart phone – Image: Noritz

All you need is to purchase and install the wireless digital control kit. However, this will also require an internet connection to enable you to control the heater remotely from your tablet, smartphone, or other connected devices. 


Although a tankless comes with a considerable temperature range, the default setting of 140o F may be too hot and uncomfortable for most users. At this temperature, there are high risks of burns and especially for children and the elderly. As such, you should consider using a lower setting. In most cases, a temperature of 120 o F is safe and comfortable for everyone, not forgetting that it helps you save on energy and water bills and the environment.

Luckily, most of the tankless water heaters in the market provide an easy control system that allows you to adjust ot customize the water temperature according to your needs.

How Point-of-Use Water Heaters Work

In your home water heating system, water is usually drawn into the heater for heating before you can access it in the hot water tap.

In the case of the tankless point of use heater, the water is heated as the water passes through it towards the tap.

These heaters are called point-of-use because they are fitted under the sink or close to the plumbing fixture.

Since it is tankless, no water is retained inside the tank, making this a more energy-efficient option.

Types of Point-of-use Tankless Water Heaters on the market

There are three points you can install these water heaters in your home. For each of these points, there is a different type made to match the need at this point.

Point of Use Tankless Heater for Shower

This one comes with a higher flow rate when compared to the other varieties.

It is installed as close to the destination as possible to ensure that you get a steady flow of water immediately you turn the shower on.

Keep the number of people who will be using the heater within a certain time in mind when shopping for a point of use heater for the shower/bathroom.

An ideal option should be able to deliver a consistent flow of hot water for four minutes, which is the average time for a quick shower.

Point of Use Tankless Heater for Washing Machine

This is a good addition if you are looking to save on energy.

Since a washing machine requires hot water, this heater will ensure enough of it whenever necessary.

Even if you do only two laundry loads every week, the washing machine point of use will save you anything between 2&5% in energy bills.

To decide which size of these water heaters is ideal for your washing machine, consider your household needs.

A larger heater will ensure that you get instant hot water for each load without overworking your unit.

Point of Use Tankless Heater for Sink

Whenever there is a sink, you can install this heater and enjoy instant and flawless hot water.

This variety can also be installed in outdoor areas where you may occasionally require hot water.

You need to keep your water pressure in mind when shopping for a point of use heater.

Some varieties will not function as efficiently at certain pressures, so you need to be sure that the unit you buy will work for you.

Point-of-Use Tankless Heater Installation

Installing this heater is easy, and if you have all the necessary tools, you can have it working in an hour or less.

The smaller units use 120v while the larger varieties run on 240v, so you need to ensure that you have the right outlet to match your heater.

For propane and natural gas-powered point of use tankless water heaters, you may need to also install a venting facility that takes out the waste gas from your house.

Since your tank’s performance, to a large extent, depends on installation, you may need to get a professional to complete the process for you.

Best Gas Tankless Water Heaters Buyer Guide

If you are looking to buy the best gas tankless water heater for your home, below are some features to consider.

Household size/Needs

A two bedroomed apartment will have a different GPM output when compared to a four-bedroom house.

If your home has only one bathroom, there is no need to invest in a heater that can simultaneously run multiple bathrooms.

The amount of hot water a heater produces depends on its power.

Your heater power of choice should be able to deliver enough hot water to match your expectations.

For a small house, 10,000 BTUs are adequate. Commercial establishments may require power of up to1,000,000 BTUs.

Flow Rate

While the power ensures that you get water at the right temperature, the flow rate will determine the amount of water you get in your hot water taps.

To determine the proper flow rate for your household, consider the number of devices you want to connect to the heater.

For example, if you want to supply all water-based appliances, you are better with a water heater with 9.0 GPM.

For a single hot water faucet, a 1 GPM flow rate is adequate.


Venting is essential for both tank and tankless water heaters.

A sound venting system ensures that hazardous gases are eliminated from your property.

With a proper venting system, you can also get additional intake from the outside whenever necessary.

The best gas tankless water heaters have two venting points that include:

Direct Venting – this Venting needs an exhaust and intake pipe.

The venting pipe eliminates carbon monoxide, among other hazardous gases, while the intake pipe ensures sufficient air intake for your gas tankless heater.

Power Venting – This Venting necessitates an exhaust pipe and a fresh air circuit.


The energy factor will help you calculate the heater’s energy efficiency and cost of operation. Most water heaters come with the energy factor listed.

A quick look at the product description will let you know how much energy is required to optimally run your unit.

Condensing vs. Non-Condensing

Condensing gas tankless heaters are more energy-efficient and easier to install when compared to the non-condensing varieties.

Also, you can use PVC in place of metal with the condensing water heaters.

The non-condensing varieties, on the other hand, are ideal for outdoor placement. They tend to be smaller, cheaper, and perfect for cabins, camping, and mobile homes.


The best tankless water heaters are not necessarily the most expensive. You can get the perfect unit for your home at a reasonable price.

A heater that is powerful enough to service multiple appliances at the same time will cost more than a small, less powerful unit.

Have your home needs in mind and then narrow your search to gas tankless water heaters within your budget.

How to Size Your Gas Tankless Water Heater?

As highlighted above, it is important to ensure that you get a water heater that will meet your home needs in the present and hear future. (Source)

To properly size your water heater, consider the temperature rise and flow rate.

Temperature Rise

Consider the normal water temperature and the output level you desire. On average, tap water gets to about 50F, and most homeowners are looking for water heaters that can raise this level to 115 degrees.

You need to ensure that the heater you choose is strong enough to heat your water to the additional 55 degrees. A less powerful heater will only slightly raise the temperature, and you will often not get the results that you are looking for.

When it comes to temperature rise, you should never compromise. Doing so will only mean that you have to endure lukewarm baths and water that is not hot enough for your other appliances.

Final Thoughts on Best Gas Tankless Water Heaters

Now you have an idea on the best gas tankless water heaters in the market and some of the features that make them stand out.

If you intend to buy one in the near future, you may want to consider any of the options listed above.

Do not forget to take your needs into account when selecting a unit for your home, as highlighted in the buying guide.

You may need to pay a little more for a powerful gas water heater, but considering these can last up to 30 years, you want a unit that will meet your present and future needs.

If you’re yet to decide the best option, then we’d recommend GASLAND Outdoors BS158

If your electric water heater is not working properly, the thermostat could be the problem. However, when you open the unit, you will see two thermostats, and you have to determine which one is not working.

Below we discuss how to test the water heater thermostat in ten simple steps.

Note: Before starting, click here to open a new tab in Amazon to search for any tools or equipment that you might need.

Steps on How to Test a Water Heater Thermostat

1. How The Thermostat Works

To understand how to test the water heater thermostat, you have to know how it works.

If your water heater is not working, then the thermostat is the culprit or at least part of the underlying problem. Replacing the thermostat may be all you need to have your heater up and running again.

Also Read: How Does A Tankless Water Heater Work?

Modern heaters come with two thermostats and two heating elements. There is an upper thermostat that is often large and the lower thermostat.

It is rare for both thermostats to fail at the same time, so you need to check which one isn’t working. Mostly, when the upper thermostat fails, the heater will not produce hot water.

If the lower thermostat is the problem, the upper one will continue heating water in the top part of the tank. This will mean that the hot water will quickly run out or you only get lukewarm water.

Below are steps on how to test the water heater thermostat.

2. Turn Off The Power Supply.

Go to your circuit board and turn off the circuit breaker. Check for the breaker labelled Water Heater inside the panel box.

Remove external access covers.

You will need a flathead screwdriver or a nut driver to complete this step. Use any of these to remove the lower and upper thermostat access panels.

Be careful to fold back the insulation used over the thermostat. You can use tape to hold the insulation in place and out of your way.

At this point, you should be able to see the interior plastic used to cover the thermostat. Remove this as well.

Confirm that there is no power getting into the water heater

It is easy to complete this step if you have a power stick. Touch the top to bottom of the multimeter connections at the same time with your power stick.

If the reading is zero, you are sure that the power supply is off. If not, some power is getting to the heater, and the last thing you want at this point is some electric shocks hitting you when you are trying to disconnect any part of the heater.

3. Check If The High Limit Reset Button Is Working Properly.

This reset button may trip if the heating element is not working or if the thermostat calibration is out. The thermostat fuse may also be closed.

4. Disconnect The Wiring

Use a screwdriver to disconnect the wiring going to each of the thermostat terminals.

For reference’s sake, you can use a camera or your phone to take a picture of how the wiring looks before disconnecting. This way, you will know which wire goes where when reassembling your unit.

5. Use A Multimeter To Check The Thermostat.

An analogue multimeter is the best tool to check the thermostat. Set it at the lowest resistance and calibrate it by bringing the probes together and ensuring that the needle is at zero.

You may also use a digital multimeter and also set it at the lowest resistance, which is usually 200 ohms.

Whichever multimeter you have, take the black probe and place it over the left side terminal and the red one on the terminal on the other side.

If there is continuity of power, the meter reading will be close to zero. If this is not the case, then it means that the thermostat is not working and you need to get a replacement.

Repeat this process on the right side and also on the lower thermostat. Once you are done testing, you can reconnect the wiring and close up the panels or take the necessary steps to get some new thermostats.

It is always advisable to replace both the upper and lower thermostats at the same time, especially if you need some extremely hot water. Fortunately, thermostats are quite affordable, so you do not have to spend much on a set.

Replacing The Thermostat

Aside from knowing how to test the water heater thermostat, you also need to know how to replace it. Below are the steps to take when replacing.

Remove the thermostat

At this point, the thermostat should be exposed, so the first step is to remove it from its casing. Use a screwdriver and a finger to bring it to the surface and remove it gently.

Be gentle not to break the bracket that holds the thermostat. If you break the bracket, you may be forced to replace the whole water heater.

Insert New Thermostat

Place the new thermostat where you removed the defective one. The bracket should hold it tight so you can have your hands free to reconnect the wires.

Reconnect all wires properly and ensure they are all firm. This is where the photo you took before disconnecting the wiring comes in handy.

Ensure that the thermostat rests firmly on the water heater; otherwise, it may not function as efficiently.

Once the thermostat is in place, set it to the desired temperature. Use a flathead screwdriver to adjust the thermostat.

A maximum temperature of 120 degrees is recommended. Higher temperatures are a scalding hazard, especially if you have children and older people in your household.

Reattach Power Supply & turn the power on

Now that the thermostat is set, put the insulation back in place, replace the protective cover and reattach the external access panels.

Go back to your electrical box and turn the power back on. Once the power is back, allow some time for the tank to recover.

Ideally, you should let the heater rest for about an hour before using it as this allows adequate time for it to recover.

However, if you are in a hurry, you should be able to get some hot water within 14 minutes.

Don’t forget to keep an eye on your water heaters performance often and act quickly whenever something is amiss.

If you the performance doesn’t improve even after replacing the thermostat, you may need to call a professional to check and diagnose your heater.


A thermostat is an integral part of your electric water heater. When it is faulty, you may have to endure cold water in your taps before it is fixed.

Fortunately, thermostats are inexpensive, and they are also easy to fix. The steps above will guide you on what to do to ensure that your water heater unit is working in no time at all.

If you grew up in a large household, you must know how disappointing it can be when you want to take a shower, but the big tank is out of hot water.

Imagine having to wait close to half an hour to shower when you have a meeting to catch?

Well, thanks to a tankless water heater, the waiting to take a bath is now a thing of the past for most people. So, how does a tankless water heater work, and what makes the unit stand out?

Tankless Water Heater Basics

A tankless water heater starts when you activate it. Thanks to its flow sensor, the heater will sense when you turn the hot water tap on, and it will automatically start producing hot water.

Unlike tank-based heaters that store up a certain amount of hot water, the amount produced in the tank-less version is based on demand.

This makes the tankless heater more efficient.

You will not have gallons of hot water sitting in the tank while you are at work or run out of water when the whole family wants to shower in the morning.

How Does A Tankless Water Heater Work- Gas vs Electric?

Gas-fired tankless heater

If the tankless water heater is gas-fired, the control panel turns the fan on, which draws enough air from the outside to open the gas valve.

The open gas-valve allows gas in, and the burner ignites so that water passing through the exchanger tubing is adequately heated.

There is a mixing valve that tempers the water so you can get it at the temperature you want.

Also Read: 5 Easy To Spot Signs of a Busted Water Heater

This tank also comes with a temperature sensor responsible for detecting if the water falls within the desired setting. If this is not the case, the sensor will adjust the gas, mixing, and flow-regulating valves to ensure that the water getting out of the tap is at the desired temperature.

There are also one or two sealed vents that extend to the roof or an outside wall. These carry out the exhaust gases while allowing combustion air into the burner.

Electric tankless Heater

This one works just like the gas-fired one. The only difference is the source of fuel, and since the wiring is done with such appliances in mind, the installation is much simpler.

Aside from how does a tankless water heater works, there will be other questions about this heater that may cross your mind.

There are some of the commonly asked questions:


Tankless electric heaters come in a variety of prices, so you are guaranteed to get one that will fall within your budget.

Gas-fired units tend to be slightly pricier when compared to electric ones.

A tankless gas-fired water heater may cost anything from $170 or thereabout to over $2000. Anything below $200 is small and only ideal for single person use.

If you are looking for a heater that can supply adequate water for two showers, you may need to check within the $1000 range.

For an electric heater, costs fall between $90 and $1000. However, there will be other costs incurred during the first-time installation process.

Installation Process

Again, this is dependent on the type of tankless water heater. Each type comes with its installation instructions which must be followed to ensure efficiency and durability.

It is always wise to involve a professional who can ensure that your heater is installed. For gas heaters, the gas connections and vent must be done right while an upgrade in the wiring and circuit-breaker panel may be necessary.


If possible, get an installer who also does maintenance so you can discuss maintenance routine when installing the water heater.

In this case, maintenance includes changing/cleaning water filters, checking the burner, and taking care of any mineral buildup.

If you live in an area with hard water, you should do a vinegar flush after every 500 hours. This will keep mineral buildup at bay and protect the heat exchanger against clogging.

The vinegar flush can be done without professional help, and it will take you half an hour or less to complete. Just follow the instructions given by the water heater manufacturer.


If you get the gas tankless heater, you should expect at least 20 years of continued service. This is two or three times the duration you get with the tank heaters.

The electric tankless heaters last about seven to ten years. Even with a shorter lifespan, these heaters can’t be compared to the tank ones in terms of reliability.

Tankless Water Heater Pros


Want hot water in your tap in a minute or less? The tankless water heater got you covered.

You can also have your entire family showered and still have hot water for your washing machine and dishwasher.

With the tankless water heater, you save on time and energy bills, making it ideal if you are looking for a more efficient home.

There are chances of leakages and spillage. You do not have to worry about a tipped over tank after an earthquake or using water that has been harboring bacteria for ages.

During installation, the exhaust and air supply vents are well sealed.

This makes it impossible for carbon monoxide to leak back into the house as a result if back drafting.

Easy to drain when necessary

If you have a vacation home, you must be aware that draining a tanked water heater takes a long time.

For the tankless one, all you need is a few seconds, and you can then unplug the heater until you are back to the home again.


Doesn’t work properly in low pressure

When answering how does a tankless water heater work question, we highlighted that this type of heater starts when the switch on button is activated.

Imagine a case where building up in the pipes reduces the water flow, or the faucet or showerhead is clogged. If the water passing through the exchanger tubing isn’t enough, the heater will automatically go off.


You may need about $1000 to get a quality tankless water heater. However, the benefits in the long run by far outweigh the cost.

5 Easy To Spot Signs of a Busted Water Heater

A water heater is essential in any home. However, just like any other appliance, your water heater will need to be replaced either because of age or usage.

While you can prolong your water heater’s lifespan by adhering to annual maintenance, chances are that you will start to see signs of a busted water heater when your unit is about to give up.

So, what are these signs, and what actions do you take once you see them?

Note: Before starting, click here to open a new tab in Amazon to search for any tools or equipment that you might need.

Signs of a Busted Water Heater


A pool of water close to your heater tank is one of the most common signs of a busted water heater. This often occurs if your water heater is six years or older.

Primarily, a leak occurs when the inner body of your water heater expands over time. This expansion leads to gaps that may allow some water to seep through.

The tank may not leak when the tank is idle, but once the tank expands during a heating cycle, the problem is observed.

Faulty connections or fittings may also cause leaks to the tank. With wrong fittings there may also be an overflow in the pipe‘s pressure and temperature.

Get a plumber to check whether there is a problem with the fittings.

Where a leak from the tank is involved, the only way to fix the problem is to replace the tank. If you do not act quickly, you may add flooding and residence damage to the list of things you need to do in the future.

Depending on where the tank is located, leaking could lead to ruined carpeting, mold growth on floors and walls, and destroyed furniture.


Steel is, without a doubt, the strongest material money can buy. However, corrosion is its biggest weakness, and once this starts, it creates weak points on the steel surface.

If you see rust on any part of the water heater, you should start getting ready to replace the unit. Rust on any surface often weakens it, and it will not be long before you start encountering more problems with your heater.

You may also notice that the water from the hot pipes is a bit rusty. This often indicates that the heater is rusting from the inside, and it is only a matter of time before it starts leaking.

It can be hard to tell whether the rust is coming from the heater or the pipes leading to the faucet, especially if the system has galvanized pipes.

 If you notice the rust in your sink or tub, try draining several buckets of hot water coming from the heater. If the water is still rusty after the third bucket, it is highly likely that the tank is the problem.

Whichever the case, a rust problem should be solved immediately for the sake of your household sanitation. You can be sure that the rust problem will soon be followed by leaks and other water heater related problems.

Malfunctioning Heating Elements

If the heating elements have malfunctioned, no water will be flowing to the tank. However, lack of water in the tank can also be caused by a build-up of sediments.

Too little hot water or water that is too hot for your comfort is also among the signs of a busted water heater. The solution may be as easy as adjusting the thermostat ideally to 120 degrees.

However, if you do not get hot water at all, the heating element may have malfunctioned. Before thinking of replacing the whole unit, first, check whether the element can be fixed.

With the right professional, you can have the heating elements solved and your heater working in just a few hours. Even if the heating element is the problem, you may need to consider replacing the heater if it is older than eight years.

Heating elements wear out faster if the heater is overworked. If your family has grown to include more members, you may consider upgrading to a heater that can meet your family’s demands without straining.

Odd Noises

A creaking, whining, or knocking inside the heater also falls among the most common signs of a busted water heater. In most cases, this happens as a result of sediment accumulation.

These sounds will be more noticeable in households that consume a lot of hot water. Once accumulated sediments have hardened, they form a layer on the tank floor that may cause any of the following problems:

  • Inefficiency as that sediments consume energy meant to heat the water inside the tank
  • Accelerated damage as the extra work done to heat water to desired temperatures wear the heater faster

If you hear sounds from your heater, you should start getting ready for leaks if you don’t move quickly.

To guarantee that your heater remains sediments-free, ensure that it is flushed at least once every year. This will drain all sediments so your heater will work more efficiently.

If you notice that the noise persists after flushing, the damage may already be done. The hardened sediments cannot be dislodged without damaging the tank.

 It is also possible that other underlying issues could cause noises.

Whatever the cause, rumbling, creaking noises from the heater normally precede leaking, so it always wise to act fast and get another heater.

It Is Too Old

Your water heater can only serve you for a certain period before it expires. If you have been renting your current home for years, you may likely replace your water heater in the course of your tenancy.

Age is also a factor to consider when deciding between repair and replacement. If you have been using your heater for over six years, replacing it makes more economic sense that repairing.

Trouble starts when you do not know how to tell how long you have to go before the water heater expires. However, simply reading the manufacture date on the heater can determine the time you have remaining before things start going downhill.

Most heaters will work perfectly for 8-10 years. The lifespan is even shorter for gas water heaters that last for 6-8 years

 This is no to say there aren’t heaters that last longer. Many homes have heaters that are up to 20 years old.

However, it is always good practice to replace your water before any of the above signs of a busted water heater begin to show.

You are better off with a new and efficient water heater than an old one that can cause damage to your home not. There is also the high-power bills that come with a heater that is not running efficiently.

There is nothing fun about burning your skin under a blistering hot shower.

If the water coming out of your heater is too hot for comfort, overheating could be the issue.

So how do you prevent water heaters overheating and continue enjoying those long warm showers?

Set The Heater At Moderate Temperature

Your electric water heater will overheat if the temperature is set too high. To rectify the problem, just set it at a lower temperature.

Normal settings range between 110- and 125-degrees. If you set it at 125 or higher, your water will be too hot.

This is not to mention the higher electricity bill you will be getting at the end of the month.

Even if you are sure that you set the correct temperature, there is always a possibility that someone else adjusted it by accident. If you know that your thermostat can go beyond 125 degrees, the temperature setting should be the first thing you check.

If yours is an entry level model, the dial for adjusting the temperature is mostly located inside the unit. Just open it up to check the readings.

Most tankless water heaters come with a digital thermostat display, so it is easy to tell the set temperature and adjust accordingly.

There are modern tankless water heaters that come with a safety function that detect any malfunctions and warn you before things escalate. If you are getting such a warning, be sure to act quickly before more damage is done.

 If you are looking to replace your heaters, you may consider getting such advanced varieties. It is much easier to prevent water heaters from overheating, among other issues, since you get alerted.

A heater that lets you know when there is a problem will save you a lot of guesswork and resources in the long run.

For water heaters mounted outside the house, there is always a possibility that someone may move it, causing the overheating problem. This should be the first place you check if you are uncomfortable with your water temperatures.

Replace the thermostat

There is also a possibility that your temperature settings are right, but the thermostat is faulty.

Thermostat issues normally arise because of normal wear and tear. If you have had your water heater for years, it may be time to change the thermostat.

With a faulty thermostat, the elements will continue heating the water to a high temperature even when you have reduced it to your desired level.  If possible, switch the thermostat off before you can get a replacement and hire a professional to fix it.

It is important to note that unless you are an expert in this field, you are better off leaving the thermostat testing to the professionals. If your heater is still under warranty, the manufacturer will often consider it void if they see that you have tampered with the heater in any way.

Going forward, you have to ensure that your heater is maintained regularly. All parts, including thermostat, pressure valve, and elements should be checked and replaced where necessary.

Take care of accumulated mineral sediments.

Water, in most cases, have natural minerals dissolved in it. Even when you have a water purification system in place, some minerals will still pass through.

When these sediments get into your water heater, they tend to cluster at the bottom of the tank and accumulate around the heating elements. Even tankless heaters may have accumulated sediments around the heating elements.

Sediments at the bottom of the tank will make it harder for the heat to transfer from the layer to the water. This problem is prevalent in gas-powered heaters.

The more the sediments around the elements, the more the heater overworks itself. The overworking happens as it tries to heat the water to the temperature set by the thermostat.

This can only translate to more overheating just before the heater malfunctions. Whatever the type of heater, regularly checking for sediments is one way to prevent water heaters overheating.

Flush the elements in the tank and remove those around the element to take care of the overheating problem. Also, ensure that the heater is flushed out whenever you carry out routine maintenance.

This will not only prolong the lifespan of your heater but also ensure that it is running optimally. You can expect to have lower power bills and enjoy enhanced efficiency when there are no sediments inside your water heater, tankless, or otherwise.

Replace the pressure valve

The pressure relief valve is designed to let out excess steam from the water. This way, the tank cannot overheat.

When the pressure valve is broken, there will be a steam build up in the tank.

A steam build-up often causes overheating inside the tank. In extreme situations, the tank may burst.

It is important to get the valve checked immediately you note that your water heater is overheating.

Checking and replacing the pressure valve may require a professional, and this comes with a financial implication. However, the cost of service and a new valve is negligible compared to how much it will cost you to get a new tank for your heater.

Clear Discharge Pipes

You can prevent water heaters from overheating by simply cleaning the discharge pipes. The process is quite easy and doesn’t require specialized skills.

Lift the supply lever and let the water flush out the heater valve for a second or two. You will notice that any residue will be quickly eliminated.

When the discharge valves are taken care of, there will be enough water supply in your heater unit, so overheating is unlikely. The same applies if there is enough water escaping from the heater through the outlet valve.

In case draining the pipe takes more than a minute, you may need to call a plumber to check out the hot water system and ensure that every part is working properly.

To check any of the above valves, you have to open the outside housing to check for defects and faults. If you do not know where to look, call a professional and possibly the one who does your heater maintenance.

With a professional, you are sure to catch minor defects before things get out of hand. The valves may appear normal, but fixing that small leak may be all it takes to prevent water heaters overheating.

Final Thoughts On Preventing Water Heaters From Overheating

These are some of the ways you can prevent water heaters overheating. If any step looks too complicated, get a professional to fix the problem for you.

You may have to pay for the service, but this is the only way you can get a proper diagnosis of what is ailing your water heater.

Flushing your water heater should feature prominently in your home maintenance to-do list.

Given the many hot water uses around a home, dealing with a broken heater is something you have to avoid at all costs.

Regularly flushing out the heater helps to get rid of mineral deposits and gunk that settle inside the heater.

Below are steps on how to flush a hot water heater.

Steps on How to Flush a Hot Water Heater

1. Turn your water heater off

A part of knowing how to flush a hot water heater is understanding what needs to be done before the process starts.

 If yours is an electric water heater, go to the power switch and switch it off. For a gas-powered heater, go to the thermostat located close to the bottom of the tank and completely turn it off or set it on pilot mode.

You may also need to switch off the gas in your gas-powered heater.

Leaving the power on when the water heater tank is empty can damage it. This step is also for your safety, and you do not want to touch the heater when there is still power running through it.

Before you start the flushing process, you may consider washing the dishes, taking a shower, and laundry because it will be a while before you can have hot water in your pipes again.

2. Turn off the cold-water valve.

The cold water from the inlet valve comes to replace the hot one escaping on the other side of the heating system. Without more water entering the tank, you can drain all the water in the heater.

Skipping this step will mean that you have a lot of water going down the drain, which can significantly increase your water bill.

3. Allow the water to cool off.

You can skip this step, but it is wise to wait an hour or two after turning off the cold-water valve to allow the water to cool off. This step is important if you plan to drain the water in your garden.

You also don’t want to handle scathing hot water at any point during the flushing process.

4. Turn on the hot water tap in the tub or sink.

The hot water taps should remain open throughout the flushing process. This prevents the formation of a vacuum in the lines when you are draining the tank.

5. Open Pressure Relief Valve

You can also opt to skip this step, but the water will drain faster when the pressure relief valve is open. It is also a way to test how well the valve is working so you will be killing two birds.

When opening the pressure relief valve, have a bucket or any large container below the drainage pipe to hold any water that comes out.

You have to be careful since the water coming out may be too hot, especially if you didn’t allow some time for the water inside the tank to cool off.

If no water comes out after opening the pressure relief valve, it is clear that the valve is broken. Consider replacing it as you flush your water heater.

6. Connect a hose to the outlet valve

Connect a garden hose to Spigot and turn it on. However, before you do so, ensure that the hose leads to a bucket or an open area outside.

If you did not allow the water to cool, make sure that the bucket is heat-proof. You also need to ensure that the hose is far from the entrance or any area that may get damaged.

If the water heater is fitted in the basement, you should consider getting a pump to bring the water up to the ground level.

Leave the hose to drain the tank until there are no sediment traces. If there were loads of sediments in the tank, you might have to drain the tank completely.

At first, the water coming out of the tank will appear brownish and get clearer as most of the sediments come out with the water

7. Flush the heater

This step is completed by opening the cold-water valve leading to the tank and allowing the water to run until the water in the hose runs clear.

If the tank had a lot of sediments, it might take a while for it all to be flushed out. Just be patient and ensure that little if any sediments are coming out of the hose by the time you wrap things up.

If there are still sediments at the bottom, try vacuuming them out using a half-inch vinyl tubing.

8. Finish everything up

Aside from knowing how to flush a hot water heater, you also need to be aware of the steps to take to have your heater working as usual.

Below are the steps you take once you are done flushing your heater.

  • Turn off the drainage valve and disconnect the attached hose.
  • If you had opened the pressure release valve, close it. This would be a great opportunity also to replace a faulty release valve.
  • Turn off the hot water taps you had opened in the tub or sink.
  • Turn the cold-water valve leading to the heater on
  • Once the water heater tank is full, open the pressure release valve to ensure that any excess air in the system is expelled.
  • If you had shut the gas off, put it on. Turn the thermostat on if it was off or relight the pilot light and then turn the thermostat on.
  • For an electric water heater, turn the breaker switch on and give your heater twenty or so minutes to heat the water.
  • Turn any hot water in the house to see if the heater is working properly. There, your heater is free of sediments, and you can rest easy knowing that it is well protected until the next time.

How Often To Flush A Hot Water Heater?

Now that you know how to flush a hot water heater, you must ensure that this is done regularly to ensure optimal water heater performance.

The flushing frequency normally depends on the model. For most heaters, an annual flush is all it takes to keep a sediment buildup at bay.

For other models, flushing the system after every three years is adequate, especially if you have a water purifier.

Be sure to check the manufacturer recommendations where flushing is concerned and follow the recommended steps to the letter.

Now that you know how to flush a hot water heater, it will be much easier to keep your unit in perfect condition. Just ensure that you do this regularly and follow all steps, as highlighted above.
