How To Turn On Tankless Water Heater

How to Operate Tankless Water Heaters

It is important to note that a tankless water heater only heats the water you use, as opposed to a traditional water heater, which continuously heats stored water in a tank. Tankless water heaters are available in two configurations: whole-house and point-of-use. A point-of-use water heater simply provides hot water to a single faucet or zone. Gas models are also available for point-of-use models, which are often powered by electricity. Changing the temperature of the water can be done from the face of the unit on both whole-house and point-of-use models, and some units even include extra capabilities that enable you to temporarily override the water temperature.

Electric Tankless Water Heater

  1. Identify and shut down the circuit breaker that supplies electricity to a small electric tankless water heater. Start by turning on all of the hot water taps that are served by the unit. Opening hot water faucets that are not linked to the water heater is not recommended. Allow the faucets to run for about 1 or 2 minutes to clear any air that may have accumulated in the lines. Activate the circuit breaker for the tankless water heater and close all of the faucets. The temperature of the water may be adjusted by turning the temperature dial. Despite the fact that you may have various temperature options to pick from on the dial, the United States Department of Energy recommends adjusting the temperature to 120 degrees Fahrenheit to avoid scorching and to lower your energy bills. Check that the water shut-off valves attached to the tankless water heater are fully open on both the intake and output water lines. Determination of the hot-water outlet that provides the greatest quantity of hot water Example: If the water heater serves both a washing machine and an entire bathroom, the bathtub faucet should be used because it provides more hot water per minute than a vanity sink or the washing machine does. Substitute a 5-gallon bucket beneath the bathtub faucet to collect water. Turn on the hot-water faucet completely and hold it there for exactly one minute. The amount of hot water in the bucket should be measured. Slowly close the hot-water outlet shut-off valve and fill the bucket for one minute at a time until the output of water is between 2 and 3 gallons per minute to guarantee that your water is constantly at the right temperature
  2. If necessary, repeat the process.

Gas Tankless Water Heater

  1. To turn off the power to your gas tankless water heater, turn off the circuit breaker that supplies it with electricity. Some versions feature power buttons that allow you to do this function right on the unit itself. Despite the fact that gas warms the water, electricity is required to run the control panel and the ignition system. Locate the gas shut-off valve that supplies gas to the device and close it. Turn the valve counterclockwise until it is in the “Off” position. Wait 5 minutes to ensure that any gas has been removed from the device. Immediately evacuate the premises and contact your gas provider from a neighbor’s residence if you detect gas after 5 minutes. Please do not make calls from your house. If you do not detect any gas, you should proceed with starting the unit. Turn the gas shut-off valve counterclockwise to the “On” position until the gas is turned back on. To restart the equipment, re-energize the circuit breaker or turn on the power switch. Temperature control arrows on the tankless water heater control panel may be used to set the temperature to 120 degrees Fahrenheit by pressing on the up or down arrows. To operate your unit from within your house, if your unit includes a wired remote that allows you to control the unit from anywhere in your home, make sure that the remote is turned on before you begin setting the water temperature using the up and down temperature arrows.

However, shutting it off and then not understanding how to switch it back on may be a very perplexing experience for some people.

However, if you have the proper instructions, turning it on will not be a tough chore to complete.

We will now begin the lesson on how to operate a water heater by turning the knob to the left.

How to Turn On Electric Water Heater?

Step one is to inspect the valves. As you did with your gas water heater, you must apply the same thinking to this situation as you did with your gas water heater. Look for any and all of the facets that are attached to the heating element. Alternatively, if you see any of them have been turned one, simply shut them. Aside from that, you must also look for any valves that may be present near the heater. If you leave them open, the air pressure within the tank will rise, causing the inside components to break as a result of increased pressure.

  1. Step 2: Allow cold water to flow through the faucet.
  2. Always make sure that the heater is fully stocked with water before turning it on to save energy.
  3. This will prevent the water from being properly heated and performing as it should as a result.
  4. Wait for a period of time until the tank is completely filled with water.
  5. Electric water heaters are equipped with a safety tag, which we utilize to switch off the heater when necessary.
  6. As a result, you must carefully remove the safety tag before turning on the power.
  7. Make certain that you are adequately protected from electric shocks.
  8. One of the most important components of the electric heaters that we use is the circuit breaker.
  9. The heater should be turned on at this point if you have followed the other steps correctly.

Connect the circuit breaker to the power source and turn it on. This will allow the heater to be ready for use when it is needed. It is necessary to hear low noises in order to determine whether or not the heater is ready to be turned on if you do not have a circuit breakers.

How to Turn Tankless Water Heater On?

There are significant differences between starting a tankless heater and other types of heaters. Due to the fact that all of the types are based on electrical ignition, the starting procedure is relatively similar, but not identical. Because they are tankless, you won’t have to waste time waiting for the heater to fill up, which will save you time. The nice feature is that these heaters may be turned on very immediately. You may learn more by following the steps outlined below. Step 1: Install a circuit breaker.

  1. But first, double-check that the circuit breaker is properly attached to the product before proceeding.
  2. Step 2: Double-check the temperature The next step is to choose an appropriate temperature for your environment.
  3. In most cases, a remote control will be included with the product as an added bonus.
  4. Standard operating procedures call for a temperature of 140 degrees Fahrenheit.

What Precautions Do I Need to Follow?

  1. It is necessary to monitor the pressure that is accessible through the discharge pipe as soon as possible after starting the process. If there are drips, this indicates that the pressure is too high. Generally speaking, it should be anything less than 80 PSI. When you switch on the water heater, check to see that no one has used it in the previous few minutes before you do so. Because all of the gas valves may still be too hot to handle, and there may also be some risks of leakage, this is necessary in most cases. Always take a close check at the naked wires or the cutters that are present within the heater before proceeding. If you come across such a situation, fix it as soon as possible without turning on the water heater. Having an adiagnosis performed on the T and P valves is the next step that you must complete. As one of the most significant components of the water heater, it is worth mentioning here. Make certain that this valve is constantly in proper functioning order. Keep your distance from the gas valve for a few minutes after you have switched it on to avoid being electrocuted. It is possible that the gas is unstable and that there are minute leaks. Direct inhalation of the gas is not recommended due to its toxicity.

Final Talk

In any setting, whether at home or at work, it should be a standard practice to turn the lights on and off at regular intervals. It helps to keep a heater in good condition and safe to use. Nonetheless, if you are experiencing any technical issues when attempting to turn on your hot water heater, you may do a short diagnosis test. Look for the issue code displayed on the screen and then contact an expert to assist you. If the heater turns on flawlessly, it indicates that all of the sensors and valves are in proper operating order.

Tankless Water Heater Not Working or Heating? Here’s What to Check First.

Tankless water heaters are energy-efficient, need little maintenance, and are relatively long-lasting in their performance. However, much like any other item, they are not fully impervious to malfunctions. They may experience small issues from time to time, such as running out of hot water or the fireplace not working. Tankless water heaters, also known as demand-type or instantaneous water heaters, are designed to supply hot water only when it is necessary. They do not generate the standby energy losses typical with storage water heaters, which can result in significant savings in energy costs.

Whenever a hot water tap is switched on, cold water is sent into the unit through a pipe from outside.

Consequently, tankless water heaters are able to provide a continuous supply of hot water.

The output of a tanklesswater heater, on the other hand, is limited in terms of flow rate.

What exactly is the problem when there is no hot water in the house yet there is cold water? This is the most typical issue that you can anticipate to encounter with a tankless water heating system. In order to get to the source of the problem, you should ask yourself the questions below.

How many appliances am I running at once?

Most likely, if you’re running the dishwasher, doing a load of towels, and taking a shower at the same time, you’re pushing the limitations of your water heater. Select the hot water activity that you require at this time, turn off the others, then restart your unit to complete the task. Many times, this is simply due to a slew of faucets being turned on at the same time, such as your shower and the kitchen sink. For example, having a shower while also running the dishwasher at the same time might cause a tankless water heater to reach its maximum capacity quickly.

You may also install separate tankless water heaters for equipment in your house that need a lot of hot water, such as a clothes washer or dishwater.

Am I reaching my minimum flow rate?

Flow rate is defined as the quantity of water (in gallons) that must pass through the tankless unit per minute in order for it to create hot water. It is likely that the unit is shutting down as a precautionary step if you are requesting less than the minimum flow rate specified. Increase the amount of water that comes out of your faucet and wait to observe whether the water begins to heat up. Tankless water heaters must be able to detect the presence of water flow in order to begin operating properly.

This is the lowest minimum flow rate available in the industry, which is a significant advantage.

Tankless water heaters that run on natural gas have higher flow rates than those that run on electricity.

Is something plugged up?

Remove any debris from your vents and air intake tubes to ensure they are not blocked. Fortunately for you, most tankless water heaters are equipped with warning devices that alert you if an exhaust vent is obstructed in any way or location. Check to see that everything, both inside and outside, is clear of obstructions, dustbunnies, and other debris. Burners that are clogged with dirt are another cause of obstruction. Make certain that they are free of debris!

What about my power source?

If you’re using power, make sure your main electrical panel is working properly. It’s possible that anything caused the breaker to trip, necessitating a reset before your tankless water heater would function properly again. If you’re using gas, check to see that your account has been paid, that you have propane in your tank, or that your gas valve is fully in the ON position.

Is it cold outside?

If your water pipes freeze over during the winter, you may be unable to provide hot water to you or your appliances.

Thaw your pipes in a safe and natural manner before attempting to get any hot water again. So what if you’re dealing with the inverse of the problem? If your water is getting too hot, these are the things you should do to cure it:

  • Stop overtaxing the system by pressing too many buttons at the same time. Set the temperature of your water heater to around 120 degrees Fahrenheit. Adjust the location of your temperature sensor in order to obtain a more accurate measurement. Inspect and clean the inlet filter on your tankless water heater. Follow the installation instructions provided by the manufacturer for your model. IMPORTANT: Whatever type of tankless water heater you have, make sure to turn it off and allow it to cool completely before performing any DIY work on it. Remove any stumbling blocks once more. A reduction in water flow might lead any heated water to become excessively hot.

A malfunctioning heater element is an issue that is exclusive to electrically powered water heaters alone. Electric water heaters can be fitted with one or two heating elements, depending on their size. If a heating element begins to ground out, it will remain on all of the time and overheat to dangerously high temperature levels. Naturally, the end consequence will be uncomfortably hot water – and that’s only to get things started! The heating element will eventually burn itself out totally over time.

  • It’s the dreaded cold water sandwich, and it’s something that happens all the time in the shower.
  • Those hot water sensations you’re experiencing at first are due to leftovers from the prior user.
  • Then, once the heater has completed its task, you will have hot water once more.
  • Using a modest storage tank to provide hot water while the tankless unit is heating up can avoid this cold water sandwich from occurring again.
  • Tankless water heaters are notorious for having this problem.
  • However, because a tankless heater requires some time to heat up the exchanger, some cold water may pass through the exchanger and reach the consumer during that period.
  • Due to the fact that gas heats up virtually instantly, but electric heaters may take a minute or two to achieve the appropriate temperature for heating, gas is the preferred fuel for space heating.

If your unit is discolored or smells nasty, it’s possible that mold, fungus, or bacteria are developing within it and causing it to malfunction.

This odor is generally generated by sulfate bacteria, which can grow in the tank over time.

The magnesium is broken down by the soft water, which results in the production of sulfate gas within the water heater.

When enough sediment accumulates, the water becomes hazy, yellow, brown, and foul-smelling.

The use of a pre-made descaling solution or normal distilled white vinegar to flush your tankless water heater should resolve your issue.

If you are aware that you have hard water issues, ask us about water softeners to assist keep your unit in peak operating condition as well.

Some DIY sources may propose draining and flushing the tank, which is not always the case.

It is necessary to ensure that the gas pressure delivered to your tankless heater is enough.

Check any sensors, wiring fuses, and electrical components to make sure they have not been damaged or burned out completely.

It is impossible for the burner to ignite if the flow rate is too low.

The following are the ignition failure codes that have been seen on several tankless brands: Tankless Water Heater by Takagi – Error Codes 111, 11 or 3 a Rinnai electric tankless water heater has encountered an error code of 11.

The failure of an ignition system on a tankless water heater can occur with any brand and type, regardless of how complex or basic it is. An internal fault with the water heater or an external problem might both cause the failure.

  • Check to see that the gas and water are turned on, and that the power (120 VAC supply) is turned on. Check to verify that the right sort of gas (natural gas or LP) is being used. Check to ensure that the pressure is within specifications. Check to verify that all air has been sucked out of the gas line before and after the installation
  • Make certain that the plumbing is installed appropriately, in accordance with local codes and manufacturer’s instructions. Check to see if the water pressure is within specifications. Make certain that the water is not excessively hard (more than 7 grains), since this might result in sediment build-up. If you live at a higher elevation, check to see if the water heater is adjusted appropriately or according to the manufacturer’s specifications. And last but not least, is there an error code

Valves and plumbing connections that are leaking in your water heater are the most common source of water leaks. If you find a leak, try to locate the source of the leak inside the plumbing system. If the problem is not immediately apparent, it is recommended that you turn off the water to your water heater and contact a local plumber in your area to come assess the issue. Please contact us if you have tried these DIY remedies and are still having problems. We are also happy to assist you with a completely other issue.

There is no tankless water heater that our plumbers in Northwest Arkansas, Southwest Missouri, or Fort Smith cannot repair or install.

How to Turn On Water Heater

Have you ever taken a shower while the water heater wasn’t working properly? Was it a pleasant experience? Most likely not. Whether you’re installing a new water heater or moving into a house that has been unoccupied for a long time, you’ll need to know how to switch on a water heater. This is a procedure that should be started many hours before you require hot water since it will take several hours for the water to get up to the proper temperature. This is a chore that may be completed by even the most inexperienced do-it-yourselfer.

Simply follow the straightforward instructions provided in this article.

Getting Started

Before we get started, we need to figure out what sort of water heater you have on your property. The procedures for installing an electric unit will be very different from those for installing a gas-fueled unit. You should also evaluate whether you want a storage-tank water heater or a tankless water heater.

How to Turn on an Electric Water Heater

The most essential thing to remember in this situation is that if a heating element is not completely buried in water, it can cause irreversible harm, therefore make sure the tank is completely filled. To do this, turn on a hot water faucet on a fixture that is close to the water heater. If you witness a constant trickle of water, you may be sure the tank is fully charged. A sputtering and hissing sound indicates that additional water is required in the tank. Check to see that the water inlet valve is fully operational.

  1. Flip the circuit toon for the matching circuit breaker. Wait (it will take several hours for the water to heat up)
  2. Your water heater may be set to a temperature of 120 degrees Fahrenheit by default, which is the setting that we suggest. Check your user’s handbook to see whether there is a knob (which may be hidden behind a cover plate) that you need to adjust to 120 degrees Fahrenheit, high temperature, or hot temperature.

How to Turn on a Gas Water Heater

This procedure is a little more time-consuming, and we dedicated a whole page to explaining it. The pilot must be ignited once the tank has been completely filled with water. For additional information, please see how to ignite a water heater pilot for more information, however here are the fundamental steps:

  1. To turn off the gas valve, first turn on the pilot light. Find the burner and turn it on. Prepare to activate pilot mode
  2. Switch on the pilot
  3. And light the pilot. Keep the gas pedal down when in pilot mode. Turn up the volume on the radio

What About Tankless?

On-demand water heaters, whether gas or electric, are simple to turn on and off. If you’re using gas, you’ll want to make sure the gas valve is closed before you begin. Transform the circuit, adjust the temperature, and finally release pressure by opening the gas valve.

For electric appliances, all you have to do is flick the circuit switch, turn it on, and set the temperature to 120 degrees. There is no waiting period in either situation. You should be able to get hot water right away.

Safety First

It’s important to remember that dealing with gas and electricity has a certain amount of danger. Make sure to turn off the electricity while working on a water heater’s electrical system, and be cautious not to leave gas valves open when they shouldn’t be. One method to improve safety is to use well-known brands, such as Bradford White, in your construction. Resources that are related to this topic include: How to Turn Off a Water Heater (with Pictures) Reset the water heater if necessary.

How to Turn on a Water Heater (12 Precautions to Follow)

There are a plethora of different types of water heaters available on the market nowadays, which may be bewildering. In your new building, you may discover a tank water heater, a tankless water heater, or a hybrid water heater, among other options. Tank water heaters were formerly the industry standard and quite popular, but tankless water heaters are becoming increasingly popular for a variety of reasons, the most important of which is their mobility. When a homeowner desires hot water delivered fast to taps or appliances that are not near to the central heater, point-of-use water heaters are the most common choice.

The following is not a lesson on which type of water heater is the most efficient, as the title indicates.

No, we don’t want you to be scrambling around trying to find a professional for everything, even this.

So How Exactly Do You Turn on Your Water Heater?

The particular procedures you must do to switch on your water heater may vary depending on the type of water heater you have. The next section will explain what you should look for when choosing a water heater and how to properly maintain one. It is vital to note that each of these procedures is critical and should not be omitted or dismissed as inconsequential. Ready? Let’s get started!

How to Turn On a Gas Water Heater

To switch on your gas water heater, simply follow these steps:

Step 1: Check For Any Open Valves or Faucets and Close Them

Starting with a visual inspection, look for any valves or faucets that may have been accidently or intentionally opened while you were working on your tank. It’s possible that someone opened it to allow a small amount of fresh air into your hot water tank. When you’re getting ready to turn on the water heater, the first thing you should do is close all of the open faucets.

Step 2: Turn the Cold Water on

The next step is to switch on the cold water supply.

The reason you’re doing this is so that your tank may be refilled. It is essential since the last thing you want to do is switch on your heater when your tank is still half-empty.

Step 3: Light Your Pilot Light

The pilot light on your water heater must be re-lit in order for your hot shower to function properly again. It is also critical to do so in order to avoid any mishaps caused by the discharge of gas.

Step 4: Turn on Your Gas Valve

If your valve is set to “pilot,” you will not be required to complete the pilot light stage as described above. All that is left for you to do is switch on your gas supply valve. At this time, the water heater should already be heating the water, and the burner should be turned on and ready to go. If you verify this on your heater and it isn’t the case, you may need to go back to the pilot light stage and repeat the process from the beginning again. This post will conclude with a link to a detailed step-by-step instruction manual.

How to Turn On an Electric Water Heater

In order to switch on your electric water heater, follow these steps:

Step 1: Check for Any Open Valves, or Faucets Close Them Up

In the same way that you check your gas water heater to see if there are any open valves or faucets, you must also check your electric water heater to see if there are any open valves or faucets. Anyone whose door is left open should be closed as soon as possible.

Step 2: Turn the Cold Water On

Make certain that your tank is completely full with water before turning on the electricity. You do not want the heater to be heating a tank that is almost completely depleted. This might cause serious damage to your tank or perhaps the heater.

Step 3: Take Out the Safety Tag

In the case that you placed a safety tag over your breaker in order to prevent anyone from turning on the switch, it is now time to remove it. If the house is not yours, it is possible that the owner has placed a tag on the switch, so be careful to double-check. If you own the house, you need get familiar with this procedure in order to avoid electric shocks.

Step 4: Turn on the Breaker

Your water heater breaker is in good working order and is ready to be turned on right now. At this point, the water heater should start heating the water to the desired temperature. Some electric water heater types may not provide any visible indication that the machine is operational. Low sounds, on the other hand, should be heard to signal that the heater has begun to operate.

How to Turn On a Tankless Water Heater

Tankless water heaters are the most convenient to operate. In order to switch on your tankless water heater, follow these steps:

Step 1: Turn on Breaker

Due to the fact that these types of water heaters are tankless (as the name indicates), you will not be required to fill it with water as you would with other types of water heaters as long as it is linked to the water supply. All that is required is that you just turn the breaker.

Step 2: Confirm Temperature

Because the heater operates on demand, you’d have to choose a temperature that’s comfortable for you. It will heat up in accordance with the temperature you select and will only begin heating up when you require it to do so. In order to avoid an accident when turning on your water heater, you must proceed with caution. Take note of the following safety measures before proceeding.

Precautions to Follow When Turning on Your Water heater

  1. Check for drips in the discharge pipe of your washing machine. It is possible that the pressure is too high
  2. If you see any drops, lower the pressure immediately (below 80 psi is low enough). Watch for the scent of leaking gas when you switch on a gas heater that hasn’t been used in a long time. Natural gas smells unpleasant for a good reason, and if you don’t know what it smells like, some people equate it to the stench of rotten eggs. This should be done before you turn on the pilot light. If there is a strong smell of gasoline, propane, kerosene, or any other flammable substance, do not re-light the fire. If you have a more recent heater, it is possible that it will prevent illumination from occurring. If you have to switch on your water heater because the pilot light has gone out, look for the source of the problem. Please do not attempt to switch the heater back on if the problem has not been resolved
  3. Test your water heater to see whether it is safe to re-light it and to see if the relief valve is operational. If you are using an electric heater, make sure there are no naked wires or debris. It is not recommended to re-light the heater until you have resolved the issue completely. You should try something different if you discover that your water heater has been tripping off no matter how many times you replace a fuse or reset the breaker. It’s possible that getting your water heater serviced is the best course of action. Keep a safe distance between yourself and the pilot light or gas valve when you’re igniting the pilot light or turning on the gas valve after that. Please keep your bare body and, in particular, your face, out of the picture! When delayed lighting happens as a consequence of a filthy burner or maybe an out-of-position pilot, you run the risk of being seriously burnt if you aren’t careful. Ensure that your burner is free of dust, corrosion, or dirt before proceeding with the pilot light. You should not use your gas stove if the burner is coated with dust, rust, or grime. Before you can ignite the burner, you’ll need to clean it or get it serviced properly. In order to ensure that the outer and inner covers of the gas valve are properly secured, check them first before turning on the gas valve. If you attempt to ignite the pilot light and the burner does not ignite, do not attempt to ignite the pilot light again. First and foremost, turn off the gas. If you don’t know how to do it, research up processes online until you find what you’re searching for. You can also enlist the assistance of a professional. Don’t forget to keep in mind that the manufacturer has provided you with a handbook. If you have any questions concerning a particular part, don’t hesitate to examine the manufacturer’s handbook. As a brief aside, never throw away the instruction manuals for any device or gadget you purchase in case of an emergency like this. If you have misplaced your manufacturer’s handbook, don’t despair
  4. There may still be a way out of your jam. Take note of the manufacturer’s name as well as the model number of your heater and check them up on the internet. They have a website, and you should be able to discover some useful information there
  5. Many water heaters have instructions attached to them by the manufacturer
  6. These instructions may also be useful in troubleshooting the water heater.


It shouldn’t be too stressful to turn on a new water heater, whether it’s for a new house or a new water heater.

With the knowledge in this article, you should be able to turn on practically any water heater without encountering any difficulties. Was this information of use to you? Please share your thoughts in the comments section below.

Tankless or Demand-Type Water Heaters

Known as demand-type water heaters or instantaneous water heaters, tankless water heaters supply hot water only when it is required. They do not generate the standby energy losses typical with storage water heaters, which can result in significant savings in energy costs. You’ll learn the fundamentals of how they function, if a tankless water heater is a good choice for your house, and what factors to consider when choosing the best model for your needs. Take a look at theEnergy Saver 101: Water Heating infographic to determine whether a tankless water heater is the best option for you, and our AskEnergySaver conversation on water heating for additional information on energy-efficient water heating.

How They Work

Tankless water heaters provide fast heating of water without the need for a storage tank. When a hot water faucet is switched on, cold water is sent through a heat exchanger in the unit, where it is heated by either a natural gas burner or an electric element, depending on the device. Consequently, tankless water heaters are able to provide a continuous supply of hot water. The need to wait for a storage tank to fill up with adequate hot water is no longer an issue. The output of a tankless water heater, on the other hand, is limited in terms of flow rate.

  • Tankless water heaters that run on natural gas have higher flow rates than those that run on electricity.
  • For example, having a shower while also running the dishwasher at the same time might cause a tankless water heater to reach its maximum capacity quickly.
  • You may also install separate tankless water heaters for equipment in your house that need a lot of hot water, such as a clothes washer or dishwater.
  • Demand water heaters are also used in the following other situations:
  • Bathrooms or hot tubs in a remote location
  • Increases the efficiency of household appliances such as dishwashers and laundry washers. Thermoelectric booster for a solar water heating system

Advantages and Disadvantages

Demand water heaters can be 24–34 percent more energy efficient than typical storage tank water heaters in residences that utilize 41 gallons or less of hot water per day on average. For houses that utilize a lot of hot water – around 86 gallons per day – they can be 8 percent to 14 percent more energy efficient than standard models. If you install a demand water heater at each hot water outlet, you may be able to achieve even larger energy savings in some circumstances. A tankless water heater will cost more up front than a normal storage water heater, but they will often live longer and have lower operating and energy expenses, which may more than compensate for their higher purchase price in the long run.

  1. They also feature readily changeable parts, which might potentially increase their lifespan by many years.
  2. With tankless water heaters, you won’t have to worry about the standby heat losses that come with traditional storage water heaters.
  3. When compared to a storage water heater, the removal of standby energy losses might sometimes outweigh the savings from using a tankless water heater.
  4. A tankless water heater’s pilot light has a cost associated with it that differs from one type to the next.

Instead of a standing pilot light, look for versions that contain an intermittent ignition device (IID). This mechanism is similar to the spark ignition system used on certain natural gas furnaces, as well as kitchen ranges and ovens, among other things.

Selecting a Demand Water Heater

Before purchasing a demand water heater, you should take the following factors into consideration:

  • Consider the following factors as well when purchasing a demand water heater:

Installation and Maintenance

It is possible to maximize the energy efficiency of your demand water heater with proper installation and maintenance. A variety of elements influence the success of an installation.

Despite the fact that it is rare, problems might develop if anything in your water heater is not functioning properly. Tankless water heaters are susceptible to a number of difficulties and maintenance issues, which are listed below:

  • Mineral buildup, system overload, cold water sandwich, air supply or exhaust blockage, ignition failure, and flame failure are all possible causes of failure.

Continue reading to understand what indications to look for when recognizing these difficulties, as well as how to resolve them!

Problem 1: Mineral Buildup

No matter whether you have a regular water heater or a tankless water heater, you should keep an eye out for mineral accumulation inside your water heater. Unlike soft water, hard water contains a high concentration of minerals, and the harder your water, the more likely it is that mineral buildup will occur, which may be harmful to your health. It is most typically calcium and magnesium minerals that generate scaly accumulation, and if you do not solve this issue, it can have a negative impact on the performance of your water heater.

This is especially critical if you use well water.

Well water can produce a more rapid buildup of debris in your tankless water heater, making it more difficult for water to pass down the long, narrow channel to the heat exchanger, resulting in reduced efficiency.

To keep your water heater from being damaged, flush it every six months using the Eccotemp EZ-Flush System Descaler Cleaning Kit.

If you do not have access to the necessary hookups to clean your water heater, you will want a valve bypass kit to aid with the cleaning.

If your water heater becomes overloaded, it may struggle to provide the hot water you require or it may even shut down completely.

You should, however, consider upgrading to a tankless water heater with a bigger capacity, or installing a second unit, if your tankless water heater repeatedly becomes overwhelmed.

Having trouble deciding which product will make the best addition to your home?

A Cold Water Sandwich is the third problem.

When you switch on the shower, you will first feel warm water, but you will then be blasted with cold water for several seconds until the temperature gradually returns to normal.

When the second shower started, the warm water you felt at the beginning was really trapped water.

Your shower may be running chilly owing to cold water accumulating in the pipes connecting your water heater and your shower.

Unfortunately, there is no way to prevent this from happening, but now that you are aware of the issue, you may refrain from hopping in the shower until the cold water has subsided completely.

The display on the majority of tankless water heaters will display an error number to alert you that your air supply or exhaust is obstructed.

The first step is to examine all vent pipes to ensure that they are correctly connected and free of puncture holes.

Installing your water heater too close to other objects might cause an air supply to be blocked, resulting in a fire danger.

Also check any vents that are situated or lead outside your property for nests of birds, mice, or wasps.

The failure of your water heater to ignite might be caused by a variety of factors.

Additionally, if your gas or water valves are not fully opened, this might result in the ignition not working properly.

If following these methods does not address the ignition problem, it is possible that your ignition pack has failed or that there is a more serious issue.

Problem number six: flame failure.

Just like with ignition failure, you should first rule out simple problems such as a low propane tank or an unpaid gas payment before moving on to more complicated issues.

Contact technical support if you need assistance with troubleshooting the issue any more thoroughly.

Despite the fact that tankless water heaters are typically low-maintenance and highly efficient, issues can occasionally arise.
