How Often Should I Flush My Tankless Water Heater?
A hearty congratulations to everyone who has just made the conversion from a standard tank water heater to a tankless model. Tankless water heaters are more energy efficient than their tank counterparts – and while they are more expensive up front, they are less expensive in the long run due to the energy savings they create on a per-gallon basis. When it comes to water heaters, one of the most often asked questions by Grove HeatingCooling plumbers is whether or not homeowners should flush their tankless water heater and, if so, how often they should do so.
Give the plumbing professionals at Grove HeatingCooling a call today if you have any questions regarding your tank or tankless water heater.
What Is a Tankless Water Heater?
Tankless water heaters are equipped with high-capacity burners that can swiftly heat water as it passes through the heat exchanger in the tank. These machines do not require the usage of a tank since they distribute water to the faucets on demand. Tankless systems consume up to 30 to 50 percent less energy than tank-based systems since they do not require the storage of water in a storage tank to function. Tankless water heaters are significantly smaller in size and may be attached directly to the wall.
Should I Flush My Tankless Water Heater?
The short answer is, without a doubt! However, despite the fact that tankless water heaters, also known as demand-type water heaters, do not keep 40 or 50 gallons of water, as typical tanks do, and so do not suffer from considerable scaling, the inner components and pipelines still require regular maintenance and cleaning. Tankless systems can become clogged with calcium, magnesium, and other minerals over time, which can impair the effectiveness of the unit and cause it to fail sooner than expected.
The heat exchanger in a tankless water heater is one of the most important components to consider.
When it comes to scaling
The Benefits of Flushing a Tankless Water Heater
Another major advantage of demand-type water heaters is that they are almost maintenance-free and may last for up to 20 years, nearly twice as long as a tank unit. Flushing your tankless system on a regular basis will ensure that it operates at peak efficiency for the longest possible time and that your house benefits from clean water and energy savings. Maintenance on your tankless water heater will guarantee that it continues to operate at peak efficiency for many years to come. Some of the additional advantages are as follows:
- It is possible to reduce the number of repairs made, increase the unit’s lifetime, lessen the impacts of scaling, and prevent blockages in the pipes. Increasing heating rates, lowering noise levels, and extending the life of the equipment are all possible.

Tankless Water Heaters and Scale Buildup
Anyone who has had a conventional water tank is aware with the necessity of flushing the tank on a regular basis in order to remove sediment. Tankless heaters are not an exception to this rule. Hard water includes minerals that can cause lime scale to build up on the surface of the water. An explosion from the accumulation is less likely with a tankless heater than with a tank model, but it can still result in some expensive complications with a tankless heater. The heat exchanger is particularly susceptible to scale buildup.
This can result in a considerable reduction in the lifespan of this component, as well as a large rise in your electricity expenditures over time.
How Often Should You Flush a Tankless Water Heater?
It is recommended that your tankless water heater be cleansed once a year to keep it operating at peak performance. However, the hardness of your water plays a role in this, and you may find that flushing twice or three times a year is preferable if your home’s water is of very low quality in this regard. To a certain extent, a sediment trap or a water softener can help with hard water.
Isolation Valves
It is critical that we explain isolation valves before proceeding with the rest of the processes. As the name implies, an isolation valve allows you to isolate (isolate) a segment of your pipeline’s liquid or gas supply without having to shut down the entire supply line (as would otherwise be the case). Essentially, the word is equivalent with the term “shut-off valve.” From your stove to your toilet, a wide range of objects in your home are equipped with some type of isolation valve for maintenance or emergency purposes, depending on the item.
Depending on the manufacturer and whether or not you had a specialist do the installation, there are several options.
Using Pumps and Flush Kits
It is critical that we explain isolation valves before moving on to the next phase. An isolation valve does exactly what it says on the tin: it allows you to cut off the liquid or gas supply (isolate) to a segment of your pipeline without having to shut down the entire pipeline. When it comes to shutoff valves, the phrase is nearly synonymous. Almost every appliance in your home, from your stove to your toilet, has some type of isolation valve built for maintenance or emergency situations. However, while these valves are available in a variety of designs, they always fall into one of the following two categories: those that rotate (such as a ball or butterfly valve) and those that move linearly (such as a check valve) (ex: glove or diaphragm valves).
How to Flush a Gas Tankless Water Heater
Check the owner’s handbook for your water heater, since it may provide specific instructions on how to flush and descale the unit. Rinnai, Rheem, and Noritz are the three most popular manufacturers of gas tankless versions. For your convenience, we’ve included particular guidelines for each of the brands listed below:
- Procedures for flushing a Rinnai tankless water heater, a Rheem tankless water heater, and a Notritz tankless water heater are all available online.
No matter what type of gas tankless water heater you have, there are a few steps in the flushing process that must be completed in the proper order, but they are all rather straightforward to complete.
Phase 1: Preparation
- Disconnect the electrical power source that is feeding the heater. Remove the access panel and check the terminal with a non-contact voltage tester to ensure that there is no longer any power coming through it. Discover where the gas isolation valve is located and close it. To prevent any water from entering the unit while you are working, locate the hot and cold shut-off valves and close them accordingly: To release any pressure, locate the hot water pressure relief valve, which should be located somewhere along the hot water line. Take cautious, because the hot water will be quite hot
- The service port for cold water and the service port for hot water will be separate. Hoses should be connected to both of these ports. Fill a five-gallon bucket halfway with water and submerge your submersible pump. The cold water pipe should be connected to your pump. Place the free on the table.
Phase 2: Flushing
- Unplug the electrical power supply to the heater
- And If there is still power flowing to the terminal after removing the access panel, use a non-contact voltage tester to confirm that this is the case. Discover where the gas isolation valve is located and close it
- To prevent any water from entering the unit while you operate, locate the hot and cold shut-off valves and close them. To release any pressure, locate the hot water pressure relief valve, which should be located along the hot water line. It is important to use caution while using hot water. Cold water service ports as well as hot water service ports will be available. Hoses should be connected to both of these ports
- Using a five-gallon bucket, put the pump into the water. To connect your pump to your cold water pipe, follow these steps: Make a free space to
Phase 3: Cleanup
- Reinstall the filter(s) in a secure manner, and then turn off the hot and cold water valves
- Replace the access panel
- Turn on the gas shutoff valve
- And remove the access panel. The electrical supply should be reconnected.
How to Flush an Electric Tankless Water Heater
Flushing out an electric tankless water heater is a little different than cleaning out a gas tankless water heater, and some disassembly may be necessary. Generally speaking, Navien models are easier to understand, however some Takagi models require additional steps in order to properly place the water control valve.
- Technique for flushing a Navien tankless water heater
- Procedure for flushing a Takagi tankless water heater
Descaling an electric model is similar to descaling a gas model in that it may be divided into three stages.
Phase 1: Preparation
- Switching off the electrical power at the circuit breaker
- Close the cold water shut-off valve on your faucet. Open your taps to let any water that has accumulated in the heater to drain
- Close the shut-off valve for the hot water supply. Remove the access panel and check the terminal with a non-contact voltage tester to ensure that there is no longer any power coming through it. Disconnect the wires from the heating elements by removing the screws that hold them in place. Extraction of the heating element is accomplished by loosening the hexagonal brass top of the heating element in a counterclockwise manner
- Make a visual inspection of the heating components for evidence of damage. A broken element should be replaced as soon as possible. Storage of the heating elements in the cooper chambers of the heater to allow for cleaning of the heating elements
Phase 2: Flushing
- Turn off the electricity at the circuit breaker
- Close the cold water shut-off valve on the faucet. Open your taps to let any water that has accumulated in the heater to drain out. Close the shut-off valve for the hot water supply
- If there is still power flowing to the terminal after removing the access panel, use a non-contact voltage tester to confirm that this is the case. Disconnect the wires from the heating elements by removing the screws that hold them together. The heating element should be removed by loosening the hexagonal brass top of the heating element in a counter-clockwise motion. Make a visual inspection of the heating components for evidence of wear and tear. When a cracked element is discovered, it should be replaced right away. In order to allow for easy cleaning, keep the heating components stored in the cooper chambers of the heater:
Phase 3: Cleanup
- Turn off all hot water faucets in your home. Close the cold water shut-off valve on your faucet. Clean any dirt from the cold water input filter by flushing the filter under a cold water faucet. Replace the filter in a secure manner. Power should be restored at the breaker once you close the access panel

Using a non-abrasive cleanser and a soft cloth to clean the device helps to maintain it clear of dust and avoid the formation of rust.
Checking pipes during cold weather is important for our northern neighbors to avoid frozen pipes.
Finally, if your tankless water heater is equipped with a pressure release valve, you should make sure it is working properly.
3. Why You Should Flush
Water heaters, like other appliances, accumulate limescale deposits over time. Failure to descale conventional tank models can result in an explosion in some instances. Tankless water heaters will not explode, but if the sediment is not flushed out of the unit, it may cause the heat exchanger to work harder than it needs to, increasing the risk of failure. The ability to keep sediment washed out not only allows the water heater to operate more effectively, but it can also assist prevent additional issues.
Consider an isolation valve to be similar to the shut-off valve on a normal tank water heater in terms of function.
It is possible that your water heater does not have an isolation valve.
4. What Supplies Do You Need to Clean the Water Heater?
We’ve covered safety; now it’s time to speak about the supplies you’ll need to flush the unit. These are the materials you’ll need: While you may purchase each component separately, a flush kit contains everything you need in one convenient package. Alternatively, you may use 4 gallons of undiluted white vinegar instead of the descaling solution included in the flushing package.
5. How to Descale a Tankless Water Heater
We’re presenting the simple methods for descaling a water heater since it’s one of the maintenance activities that many homeowners can complete with little or no help from a professional. The first step is to turn off the power that is feeding your water heater. Locate and close the gas isolation valve if one exists. Shut off the hot and cold water shut-off valves while you’re working on the unit to prevent water from entering the unit. If your machine is equipped with a pressure relief valve, carefully open it to relieve any built-up pressure.
Next, put the submersible pump in the bucket you just made. The cold water line should be connected to the pump, and one end of the hot water hose should be placed in the bucket. You have two options: either pour four gallons of vinegar or pour four gallons of water.
6. Final Steps for Tankless Water Heater Cleaning
Closing the cold water service port and opening the cold water shut-off valve are the next tasks you need to do. This step removes any vinegar that may have remained. Following that, you’ll close the valve and allow the water to drain completely. It is now necessary to shut the hot water port. Finally, if there is a cold water input filter, make sure to remove it as well as the hot water in-line filter before continuing. Flush both of them in the sink to ensure that any remaining sediment is removed.
Keep in mind that, while it might be a fun DIY project, you may feel more comfortable having a professional plumber complete the task.
Need to Schedule Tankless Water Heater Maintenance?
Maintenance, including tankless water heater cleaning, should be performed at least once a year to ensure that everything is running well. You may need to perform additional duties, such as cleaning off the unit’s outside, on a more frequent basis, especially if the location where the water heater is installed receives a lot of dust.

It is a common misconception that a tankless water heater requires annual maintenance; however, according to Jason Fleming, marketing manager at Noritz, this is not true.
Flushing a Tankless Water Heater Regularly is Important — Here’s Why
Homes are becoming more refined in their mechanical component selection as the technology underpinning building systems continues to advance. Once buried beneath concrete-block foundations, inefficient and bulky machinery has been replaced by sleeker, more energy-efficient machines with longer life spans that purr while providing consistent comfort. The combination of flexible hoses with these flush kit valves allows users to pump descaling solution into the system through the cold-water side and out of the system through the hot-water side.
Photograph courtesy of Matt Risinger Tankless water heaters are an excellent illustration of this. Tankless water heaters are becoming an increasingly popular option for propane-powered houses since they take up less space and heat water only when it is needed, so conserving fuel.
Flushing the system
A system flush is the most important piece of preventative maintenance for tankless water heaters. This procedure entails circulating a vinegar solution through the device in order to break down scale accumulation. Even while many plumbing businesses are willing to execute the job for a charge, manufacturers often provide instructions and supplies requirements for homeowners who want to do it on their own time. “These days, flush kits are installed in practically all tankless systems,” adds Risinger.
A series of YouTube films has been created by Risinger to describe the technique in detail.
After
How often to flush
Tankless water heaters that are newer than five years often have flush kits installed during the installation process, making DIY flushing a simpler task. A professional will be required to do the maintenance on an older tankless device that does not include a flush kit. Photograph courtesy of Matt Risinger Tankless water heaters should be cleansed once a year, as opposed to tank-style ones, which can operate for several years without needing maintenance. In most cases, the frequency is annual, unless the water quality is low, in which case it is advisable to do so more regularly, according to Federico.
Some systems can even be remotely monitored by the plumbing business that serves the house.
Water softening helps
The flush kits that come with newer tankless water heaters are often installed during installation, making DIY flushing a less difficult job. It will be necessary to hire a professional to handle the maintenance on an older tankless unit that does not include a flush kit. Matt Risinger provided the photograph. Tankless water heaters should be cleansed once a year, as opposed to tank-style ones, which might last many years between maintenance. In most cases, the frequency is annual, unless the water quality is low, in which case it is advisable to do it more regularly, according to Federico.
Depending on the equipment, the plumbing business can even monitor it from a distance.
Not flushing is hazardous
Calcium particles created by scale accumulation in tankless water heaters can block faucet aerators such as this one or become stuck in screens behind shower valves, causing them to clog or fail to function properly. The outcome can be expensive behind-the-walls repairs, but this is avoidable by doing regular water heater maintenance on a regular basis. Photograph courtesy of Matt Risinger Even though the majority of a home’s mechanical systems are rather hands-off, Risinger warns against neglecting tankless water heater maintenance.
The particles will build behind aerators and valve screens throughout the home’s plumbing system, making it more expensive and cumbersome to repair or replace the components.
In spite of the fact that tankless water heaters are quite cleanable, if you wait too long between cleanings, it will begin to harm other systems.”
Easy Maintenance Tips for Tankless Water Heaters w/Photos
A little ‘how-to’ information may go a long way toward ensuring that your tankless water heaters operate at peak efficiency. As a result, not only will you save money on plumbing expenses, but you will also extend the life of your tankless water heater. You may be asking yourself right now, ‘what are some tips for keeping my tankless water heater in good working order?’ Is it necessary to do periodic maintenance on tankless water heaters? Tankless water heaters, like any other type of water heater, require periodic maintenance.
Because of hard water or the amount of hot water your household consumes, you should anticipate to do this once a year at the most.
Do You Need to Flush Your Tankless Water Heater?
The majority of people are aware that they must flush a tank-style water heater. Most people, on the other hand, are unaware that they should also flush their tankless water heater. Yes, tankless water heaters do require flushing on a regular basis. It is necessary to flush the tankless water heater to eliminate limescale accumulation on the burners within. Typically, flushing is required every 2 to 3 years in the majority of situations. When flushing maintenance is necessary, tankless water heaters will automatically shut down and display an error code on the display.
The number of minerals present in the water supply has an impact on the hardness of the water in the tap.
As the water warms, the sediment separates from the water in the same way as it does in a tank-style water heater.
How to Flush and Descale a Tankless Water Heater
It is necessary to do periodic maintenance on a tankless water heater in order for it to operate properly. It is possible to flush your tankless water heater in order to clean and remove mineral deposits from the burner system by following these steps:
Supplies You Will Need:
- 5 gallon bucket, 3 gallons pure white vinegar or descaling solution, 2 clothes washer hoses, channel lock pliers, 2 clothes dryer hoses
It is possible to acquire the My PlumbingStuff – Tankless Water Heater Flushing Kit – 32-ounce at this location. User Instructions for the J.C. Whitlam FLOW32 Flow-Aide System Descaler – Zoeller 42-0007 Floor Sucker Pump – 5-Gallon Bucket – Safe to Use. This practical set comes with a 5-gallon bucket, two hoses, a descaling solution, and a sump pump, among other things.
Directions for Flushing Tankless Water Heaters:
The connections under the tankless water heater may be accessed by removing the cover on top of the unit. Some tankless types may not have a cover fitted at the time of purchase.
Step 2: Verify your tankless water heater has a flushing kit installed
If the flushing valves on your tankless water heater are not there, check to see if they have been installed. Stop what you’re doing and call a qualified plumber to install them.
Step 3: turn off the gas supply
Turn off the gas feed to the tankless water heater at the main shutoff valve.
It will be necessary to switch the gasoline supply such that it is “perpendicular” to the fuel line. It is not necessary to cut off the electricity to the electric thermostat.
Step 4: Turn off the water supply
Close the cold water supply valve, which is responsible for supplying water to the tankless water heater, to prevent it from being used. Cold water is prevented from entering the unit as a result of this. Close the hot water supply valve, which is responsible for delivering hot water from the tankless water heater to the rest of the home. Shot water is prevented from entering the home as a result of this. Use this opportunity to inspect your temperature and pressure relief valve (T P valve) to confirm that it is in proper operating order.
Step 5: Open the flushing valves and connect the hoses
Remove the caps from the flushing valves and set them aside. This is important in order to relieve any pressure that has built up inside the valves. Connect the hoses to the flushing valves and tighten the connections with channel lock pliers to ensure that they are secure. Check to see that the rubber washers are properly seated in the tube to ensure a tight seal and avoid leaks. The flushing valves should be opened by rotating them 90 degrees at right angles (or perpendicular) to the existing positions of the cold and hot valves, respectively.
Step 6: Setup the bucket and sump pump
Add descaling solution or white distilled vinegar to the 5-gallon bucket until it is completely filled. Lower the sump pump into the 5-gallon bucket filled with descaling solution or distilled vinegar, and then turn on the sump pump to start the cleaning process.
Step 7: Flushing the tankless water heater
Using a descaling solution, allow the sump pump to run for 30 minutes; if using vinegar, allow the sump pump to run for 1-2 hours. Using this method, the cleaning solution will be pumped through the water heater and into the pipes to be cleaned. Completely switch off the sump pump once the job is done. Remove the hoses and pour the cleaning solution container into a trash can. Using clean water, rinse off any residual descaling solution that may have accumulated in the bucket. Until the water running through the system is clear, you’ll need to repeat this procedure several times.
Step 8: Finishing up and closing the system
The hosing should be removed from the flushing valves. Replacing and tightening the purge port caps properly is essential. Take care not to damage the rubber seals that are contained within the caps. If you do, you must replace them as soon as possible.
Step 9: Check the sediment filter
The sediment filter is situated on the cold water input line that feeds into the tankless water heater system. Remove the sediment filter by unscrewing it and wiping it off with a damp cloth if necessary. When you’re finished, remove the filter and replace it.
Step 10: Open the water supply to the tankless water heater
Rotate the cold water supply and hot water supply valves so that they are in line (or parallel) with the pipes before opening each of the valves.
Step 11: Turn the gas on to the tankless water heater
To finish, turn on the gas supply valve so that it is in line (or parallel) with the pipe system. Start by turning on the hot water faucet. This will drive any trapped air out of the pipe that has been stuck there. Run the water for as long as it takes for all of the air to be expelled, which is about 2-3 minutes in total.
Items should be cleaned and stored for use the following year. That’s all there is to it! This is a step-by-step guide on cleaning and maintaining your tankless water heater. Not only have you expanded your handyman skills, but you’ve also saved money by not having to hire a plumber!
When Should You Descale a Tankless Water Heater?
Descalement of your tankless water heater does not have a specific schedule for when it should be performed. This will be highly influenced by the hardness of the water in your location. Tankless water heaters should be descaled once a year if you live in a region with extremely hard water. You’re not sure if you have hard water or not. You may use theHealth Metric Drinking Water Test Kit for Home Tap and Well Water, which is an EPA-recognized at-home water analysis kit, to assess the quality of the water that is coming into your home from your water source.
