How To Flush A Rinnai Tankless Water Heater

How do I flush clean my Rinnai tankless water heater? (R)

It is possible for a tankless water heater to collect mineral build-up over time, which can corrode the walls of the heating chamber within the tank. For regular maintenance and cleaning of your tankless water heater, it is necessary to rinse those mineral deposits out at least once a year using a hose. Follow this straightforward procedure to guarantee that your tankless water heater performs and operates at peak efficiency. Please take the time to go through all of the directions before starting, as you’ll want to ensure that you have all of the essential items on hand for the procedure.

  • During the cleaning procedure, this stops cold water from entering the water heater and hot water from exiting the water heater. The water valves are comprised of three parts: a cold water valve (which is colored blue), a hot water valve (which is colored red), and a main valve, which is responsible for bringing water into your home.

4. Remove the purge port valve caps from the purge valves situated on each of the cold and hot water valves one at a time, taking care not to damage them.

  • The purge valves are distinguished by their little handles that mimic the letter “T.” In order to alleviate any pressure that has built up inside the valves and to avoid excessive hot water from pouring out during the cleaning process, this step must be carried out. Because there may be pressure when removing the purge port valve covers, it is critical to double-check that the hot water valve has been properly switched off for your safety. Make sure to handle each cap with care to ensure that the rubber sealing discs remain in place. These are required in order for your valves to operate correctly.

5. Connect a hosing line to each of the three valves in the system.

  • Tankless water heater hosing lines are available at any home improvement store that carries water heaters if the manufacturer did not include them with your tankless water heater. There must be adequate length between the water heater and the bucket for the hosing lines to be effective. Please refer to the tankless water heater manufacturer’s instruction manual, or contact the manufacturer directly if you require specific instructions on how to do this step. In certain situations, you may be required to utilize a sump pump and connect hoses in order to discharge and flush water from the tankless water heater’s cold and hot water valves during this operation.

6. Twist the purge port valves so that they are perpendicular to the positions of the cold and hot valves, and then close them. 7. To clean your tankless water heater, fill a 4-gallon (15.1-liter) bucket halfway with undiluted white vinegar. Never apply any type of chemical solution on your skin.

  • Sixth, twisting the purge port valves in a direction perpendicular to the cold and hot valve positions will allow the purge ports to be opened. 7. To clean your tankless water heater, use 4 gallons (15.1 liters) of undiluted white vinegar. Never, ever use any type of chemical solution.

8. To complete the flushing and draining operation, according to the directions provided in your manufacturer’s handbook. 8. To complete the cleansing and draining operation, according to the directions provided in your manufacturer’s handbook.

  • Tighten the caps all the way down and securely. Take care not to overtighten or damage the rubber sealing discs that are contained within the caps, though.

Remove the tops from the jars and tighten them fully. It is important, however, to avoid overtightening or breaking the rubber sealing discs that are included within the caps.

  • If this is the case, you may need to rotate and open the cold and hot water valves so that they are parallel to one other and the main valve’s position.

Pick a sink tap within the house and turn on the hot water gently, allowing enough time for air to travel through the pipe.

  • Make sure to keep the water running until it flows consistently and there is no air escaping (you may recognize this by a slight sputtering sound). It might take up to 2 or 3 minutes for all of the air pockets to be expelled from the system.

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

  1. 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
  2. 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. Into the bucket, insert the free end of the hot water line
  3. Pour four gallons of undiluted virgin food-grade white vinegar into a pail and set it aside. In addition, Noritz recommends diluting one gallon of CLR with three gallons of water for heavy-duty applications.

Phase 2: Flushing

  1. Make sure that the hot and cold service ports are open and that the pump is running. Make sure the vinegar is allowed to flow through the heater for at least one hour (longer if the pump runs at less than four gallons per minute). As a result of this, the scale is broken down and the silt is flushed away. Turn off the pump and empty the vinegar into a trash can. Close the cold water service port and disconnect the hose that is connected to it. Open the cold water shutoff valve to let any residual vinegar to be flushed out through the second hose into your bucket for around ten minutes. Close the cold water shut-off valve on your faucet. Allow the water to drain completely before disconnecting the second hose. Close the hot water service port on the boiler. Remove the cold water intake filter as well as the hot water inline filter (if applicable). Remove any retained sediment by flushing the filters with water in a sink.

Phase 3: Cleanup

  1. Activate the pump by opening the hot and cold service ports. Allow for a minimum of one hour of circulation of the vinegar through the heater (longer if the pump runs at less than four gallons per minute). As a result, scale is broken down and silt is flushed away. Tossing out the vinegar after turning off the pump Removing the hose from the cold water service port and closing the port To flush out any residual vinegar via the second hose into your bucket, turn on the cold water shutoff valve for approximately 10 minutes. Close the cold water shut-off valve on the faucet. Allow the water to drain completely before removing the second hose. Removing the hot water service port from the system. Remove the cold water intake filter and, if applicable, the hot water inline filter from the water supply system. Remove any retained sediment from the filters by flushing them down the drain.

Descaling an electric model is similar to descaling a gas model in that it may be divided into three stages.

Phase 1: Preparation

  1. When descaling an electric model, the process is similar to that of descaling a gas model.

Phase 2: Flushing

  1. Fill the cooper chambers with virgin food-grade white vinegar that has not been diluted
  2. Pour vinegar into the chamber and allow it to rest for 90 minutes to two hours. Using this method, you may break up any scales on the components. Remove the vinegar from the mixture. Replace the heating elements and reattach the cables as necessary. Open the cold water shut-off valve and let the tank to fill up with cold water
  3. Observe the tank for any evidence of leakage (the paper towel test is quite effective in this situation)
  4. To turn off the hot water, turn the shutoff valve. Fill the sink with warm water from various hot water taps and let the water run for about five minutes to flush out the vinegar and remove any air pockets from the line

Phase 3: Cleanup

  1. 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

How to Flush a Rinnai Tankless Water Heater

Rinnai tankless water heaters should be flushed at least once a year to avoid the accumulation of minerals and deposits that can form inside the heater. This buildup is created by hard water and might pose difficulties in the future by limiting the flow of water at both the input and outflow of the system. Fortunately, flushing a Rinnai tankless water heater is a relatively straightforward task that can be completed in as little as half an hour with a few simple tools. How to flush your Rinnai Tankless water heater yourself and save money while also learning a new skill is outlined in this step-by-step instruction manual.

How to Flush your Rinnai Tankless Water Heater

Cleaning a Rinnai tankless water heater begins with gathering all of the gear that will be required to do the work accurately and efficiently. These include, but are not limited to, the following:

  • Pliers with open jaws
  • A little pipe wrench Three (3) 5 gallon buckets (one with a lid)
  • Two (2) washing hoses
  • Three (3) 5 gallon buckets (one with a lid)
  • A submersible pump with a capacity of 4 gallons per minute is used. a gallon of white vinegar (four gallons)

It is necessary to turn off the tankless water heater as a first step in order to begin the operation. This is critical because if the water heater is turned on, the water heater will immediately begin pumping water. If the system is open at the time of this occurrence, the consequence will be a complete disaster. To proceed, close both the hot and cold isolation valves and attach the two water hoses to the service ports on both the hot and cold isolater valves. Step 2 This is done in order to allow the vinegar solution to flow through the valves and pipes of the plumbing system.

  1. This will ensure that the vinegar solution is introduced into the system on a constant basis until the flushing process is done.
  2. Because it will also be eliminating the minerals and deposits left behind by the hard water, the volume of solution pushed out of the system may be somewhat more than the amount of solution injected into the system.
  3. Step 5After that, the vinegar is poured into a bucket and the submersible pump is turned on to start the process.
  4. In most cases, the manufacturer recommends cleansing the system for at least 45 minutes, but the longer the better, especially in places with extremely hard water sources.
  5. Rinnai tankless water heaters have components such as a blower fan, burners (for natural gas), and fins on the heat exchanger that help to heat the water.
  6. Step 7After the flushing process is complete, the discharged solution is disposed of properly.
  7. Once the discharged solution has been collected in the bucket, the bucket should be closed and sealed with the help of the lid.
  8. Researching the local criteria is recommended by professionals as a starting point.
  9. Using fresh water, four gallons of it is placed inside the bucket with the pump, and the fresh water is pumped through the system until it reaches the third discharge bucket.
  10. Eighth step: Shut off the circulation pump and close the service port on the cold input to prevent water from entering.
  11. As a result, the circulation of cold water into the heater will be reinstated.

Following that, the cold input valve is opened to allow fresh water to cleanse the system for a third time, but this time there is no need to collect the water that was previously collected.

Skipping yearly maintenance is the most common cause of premature failure, and doing so may result in the voiding of your guarantee. Proper inspection and maintenance will ensure that your heater operates at peak efficiency and for the longest possible time. Continue reading to discover how to properly maintain your Rinnai tankless water heater on an annual basis.

Annual Inspection Steps

Checking the error-code history of your Rinnai tankless water heater is the first step in doing an annual inspection on your tankless water heater.

This will notify you if something occurred that resulted in the occurrence of an error code that you were not previously aware of. The following is how you may look up the history of error codes:

  1. Push the Hot Water power button
  2. Press the down-arrow button
  3. And then press the power button again.

After you have completed this procedure, the device will indicate whether or not there have been any error codes. This will appear as a “e” followed by the code number shown on the unit’s display screen. If there are no problem codes, then you may go to the following stage without further delay. ‍

2. Remove the front panel of the water heater

While it is simple to remove the front panel of your water heater, it is important to do it with care so that you do not damage the tabs that keep the panel in place. On either side of the front panel, there are two decorative strips that add to the overall appearance. Pulling the left side strip straight to the left and then pulling the right side strip straight to the right can help you get rid of them. 2. Remove the four panel screws from the back of the panel. After you have removed the panel strips, you will need to remove four screws from the panel assembly.

This is accomplished by tilting the bottom forward and elevating it off the ground.

3. Inspect the Flame Rod

After removing the front panel, we can see inside the burner to ensure that the flame rod is functioning correctly, if necessary. In the center of the room will be a sight glass that will allow you to gaze through it to observe tubes within that are dispersing fire. When inspecting the heat-exchanger area, look for a very clean blue flame coming out of the flame rod into the heat-exchanger region, where water is heated as it passes through. You will be able to see a red flame erupting over the entire heat exchanger region, which is precisely what you want to see.

That the gas pressure is correct and precisely where it should be is indicated by this indicator.

4. Remove and clean the air filter screen

Because your Rinnai tankless water heater has a fresh air intake, a screen has been installed to prevent bugs and debris from entering the unit. The air filter is placed in the upper right corner of your unit and will move out in the direction of your body when you turn the unit on. Make sure there are no detachable objects and then reinstall it. If there is blocking material in the air filter, it may cause your unit to not have the right air-gas combination, which is why we do this. It may not function correctly as a result of this.

5. Remove and clean the cold water filterflush heater with vinegar ‍

It is possible to see a sequence of pipelines and valves underneath the device. For this stage, we are just concerned with the water input and outflow pipes, which are the two inner pipes that lead up into the unit from the outside. 1. Turn off the cold and hot water domestic water valves on the main water line. If you continue to follow those two inner pipes, you will eventually come upon a double-valve arrangement. Close both of these valves to prevent water from entering or exiting the heater, thus isolating it so that you may clean the cold water filter.

  1. Remove the lid from the cold water valve.
  2. Remove the cold water valve cap from the cold water intake pipe, which is located in front of the double-valve assembly.
  3. 3.
  4. A cold water filter is located at the point where the cold water intake line joins your unit.
  5. Remove the cold water filter and check it for any dirt or residue that may have accumulated.
  6. After that, replace the filter with a new one.
  7. That is how you will tell if it has been properly sealed and tightened.

4.

If you haven’t previously, replace the cover on the cold water valve and turn off the blue valve that leads to the cold water valve.

5.

Connect the service hoses to the hot and cold water lines, if you haven’t previously done so.

Pour the water from the heater into a 5-gallon bucket and allow it to drain for about 5 minutes to ensure that all of the water is removed.

Using the line that comes from the cold water input valve, connect it to the sump pump.

Turn on the hot and cold water valves on the service lines by pressing the on button on the valves.

For around 30 minutes, circulate the vinegar through the system.

Turn on the cold water supply at the main valve.

Allow the system to cycle for about 5-10 minutes to verify that all vinegar has been eliminated.

Remove the hose from the hot water service valve and turn off the hot water service valve. Caps should be replaced on both the hot and cold service ports. Turn on the hot and cold main water lines by turning the knobs on the faucets. After that, re-energize the heater.

6. Replace the front panel

Finally, in order to complete your yearly inspection, you will need to replace the front panel of your appliance.

Flushing Tankless Water Heaters – Tips on How to Flush Properly

Tankless water heaters should be flushed according to a simple step-by-step procedure. Don’t make educated guesses; learn when and how to flush your tankless heater. If you want to keep your tankless unit running at peak efficiency, heating efficiently, and lasting a long time, basic cleaning and draining away the limescale and sediment accumulation is the way to go. When compared to traditional tank-type water heaters, tankless water heaters do not store hot water. It is through the heat exchanger that the cold water is heated by the gas burner, which is often positioned beneath the heat exchanger.

Why flushing a tankless water heater is important

Rinnai tankless water heater is a type of water heater that does not require a tank. Because water quality can have an impact on the performance of a tankless water heater, every manufacturer of tankless water heaters suggests routine cleaning and maintenance, with flushing being the most comprehensive. Given the prevalence of hard water in many families, particularly those who rely on well water for their water, it is possible that the heater will acquire limescale and mineral deposits on its components.

  • This can result in a clogged element, a lack of regular heating operation, and other issues.
  • As can be seen, the heat exchanger is the most crucial component of a tankless heater’s construction.
  • If this is not done, the condition will worsen.
  • Rinnai, for example, may display “LC” and “OO” error codes on the remote controller or display, indicating that there is a problem and that flushing is necessary.

Note: It is important to remember that the warranty does not cover any damage resulting from limescale accumulation. – Locate Plumbers in Your Locality –

Instructions on how to flush a tankless water heater

As previously said, cleaning a tankless water heater is not difficult, and after it has been completed correctly, you must reset the fault code by turning off the electricity. (I’ll assume that isolation or service valves have been placed.) Here are the step-by-step instructions:

  • Turn off the power to your tankless heater (both the electricity and the gas)
  • Close the valves on the hot and cold water lines at the same time. Connect the circulation pump (such as a pond pump) to the cold water line by using the service (isolation) valve and connecting it to the cold water line (garden hose is OK). When the flushing solution is forced into the heater, the circulation pump is activated. In order to prepare the flushing solution, roughly 4 gallons of food-grade white vinegar should be used. Alternatively, you may purchase a delimer directly from the tankless manufacturer if necessary. The use of a cleaning solution that is non-toxic, non-corrosive, and biodegradable is highly suggested Empty the bucket and fill it with the cleaning solution (vinegar or delimer)
  • Connect the hose to the heater using another service valve and end it in the proper drain bucket
  • This is the final step. It is recommended that the drain and pump hoses end up in the same bucket and into the cleaning solution Activate both of the service valves on the hot and cold water supply lines. Turn on the circulation pump and let the flushing solution to circulate through the device for roughly one hour. Turn the pump off if it is running. Clean out the water heater by opening the shutdown valve on the cold water line (and closing the service valve between the pump and heater), allowing the cleaning solution to flow through the heater and into a bucket (approximately 5 min.) Open the shutdown valve on the unit and close the service valve that connects the heater to a bucket after that. Remove all of the hoses from the system. In addition, it is recommended that the in-line filter be cleaned. Continue to use the electricity and turn on the water heater

TheRinnaimanufacturer suggests that you follow the instructions outlined in the preceding literature. This is a safe and effective method of flushing tankless water heaters, which may be performed by the heater’s owner or a professional plumber. As an alternative, you may purchase a flush kit, which often contains a pump, hoses, hose adapters, a bucket, and descaler, among other things. The kits are compatible with tankless valves and may be quickly and simply installed. Tankless water heater manufacturers recommend draining the mineral deposits out of the system at least once a year, or more frequently if you live in a region where the water is very hard.

Rinnai Tankless Review

This review focuses on the Rinnai RUR98eN tankless water heater, although it also discusses several topics that are common to all tankless water heaters. When I was looking at my future house, the inspector made it plain that my water heater was in poor condition: it was ancient and in desperate need of repair. It was a Bradford-White water heater, and it had been doing its job faithfully since 2002. It’s common for new homeowners to remark that they have other priorities that need to be handled first.

  • After three or four years, my water heater began to make gurgling noises and failed to heat the water to a scorching high temperature any more.
  • It had come to the point where it needed to be replaced.
  • Because I didn’t want the water heater in that central closet longer, I moved it elsewhere.
  • The removal of the water heater from the interior of the home would also minimize damage in the event that any of its components failed.

Why tankless?

A lot of people had talked about tankless water heaters, and I believed it would be a fantastic alternative for my household. I had listened to a couple of compelling arguments that I thought were worth sharing (and their relative truth in my situation).

  1. In addition to being more energy efficient, tankless water heaters also provide an unending supply of hot water. In addition to being more environmentally friendly, tankless water heaters will also save me money in the long run. Tankless water heaters are more space-efficient than traditional water heaters.

The second and fifth arguments convinced me to get a hot water heater. A constant stream of water was important to me, so I installed a continuous stream of water in my house and built an additional storage closet in it.

Let’s talk about cost

Tankless water heaters do not save you money on your energy bills. When compared to traditional water heaters, tankless water heaters are more expensive to acquire and install, and the additional money spent will not be recouped by lower water and energy use. $1250 would have been the cost of a straightforward tank water heater replacement. What is the breakdown of that?

  • The water heater alone cost around $750, with a $250 installation fee imposed by the plumber. Additionally, the city demanded an additional $250 for the permit (which the plumber was obligated to get)

Anything that has to do with 220 volt power, water, or natural gas is permitted. There is nothing I cut corners on in my home when it comes to those components. The tankless water heaters I was considering were around 2-3 times the cost of their tanked counterparts. Based on where I choose to install the hot water heater in my home, the cost of installation varied dramatically. This would not have been possible with the current gas line since tankless water heaters require a significantly larger gas line and venting system than their traditional tanked equivalents.

It’s all about flow

Anything that has to do with 220 volt power, water, or natural gas is permitted by my permission. Regarding such components, I do not take any short cuts in my home. Compared to conventional water heaters, tankless water heaters were around 2-3 times more expensive. Based on where I choose to locate the hot water heater in my home, the cost of installation varied dramatically. Because tankless water heaters require a considerably larger gas line and venting system than their tanked equivalents, I was unable to use the existing gas supply.

Placement Matters

Let’s have a look at the plumbing system in a typical home setting. There are two bathrooms in this one-story residence on a single level. Currently, the water heater is located in the middle of the residence. One of the bathrooms will benefit from having virtually immediate hot water as a result of this. The kitchen, garage, and bathroom 1 on the other hand, have a lengthier wait for hot water than the others. An example of a plumbing plan. Connection to the water provider was skipped, and outside fixtures were left out for the sake of brevity.

I chose option number one.

Gas/Power Install Venting Install Risk Warmup Time
Attic $$$ $$$ ‍♂️
Outside Bath 1 $$$$$ none Bath 1: Everything Else:
Inside Garage $$ $$$ Laundry: Everything Else:
Outside Garage $ None Everything:

Let’s have a look at the plumbing system in a typical home environment. There are two bathrooms in this one-story house on a single level. In this particular instance, the water heater is located in the middle of the home. One of the bathrooms will benefit from the near-instantaneous hot water provided by this. Hot water takes longer to reach the kitchen, garage, and bathroom 1, on the other hand. Plumbing layout example. Outdoor fittings were left out for the sake of brevity because of the water line connection.

I chose option number one because the attic was available.

Enter recirculation

Let’s take a look at the plumbing system in a typical home. This house has two bathrooms and is on one story. Currently, the water heater is located in the center of the home. One of the bathrooms will benefit from the near-instantaneous hot water. The kitchen, garage, and bathroom 1 on the other hand, have a lengthier wait for hot water. Typical plumbing arrangement. Connection to the water company was omitted for the sake of brevity, as were exterior fittings.

A new hot water heater might be installed in a variety of locations, including the attic above the closet, outside of bathroom one, within the garage, or on the exterior of the garage. Each area has its own set of advantages and disadvantages, which are detailed below:

Water heaters are smart?

Yep! I’ve been experimenting with Google Home to automate various areas of my home in recent months. Rinnai advocated for the use of Google Home connectivity. Although it is a useful function, the implementation is poor and the interface is difficult to navigate. Once everything is set up, I may communicate with my water heater in the following ways: Hey, Google, get in touch with Rinnai. – Hello and welcome to Rinnai. What exactly can I assist you with? Bring on the hot water. -Beginning of recirculation While it may appear to be hip at first, the novelty rapidly wears off.

  • It’s infuriating to be told over and over, “since your voice wasn’t detected, I’m unable to do that right now.” When I get up in the morning and require hot water, my voice is generally not in sync.
  • Unfortunately, the Google connection is little more than a haphazard marketing tool that was implemented without much thinking.
  • The software quality of this item, in addition, is substandard, Apple’s iPhone application is frequently problematic, and the error messages are often ambiguous at best.
  • Furthermore, the two plumbers I hired to come to my house to install and service the water heater lacked the software understanding necessary to set up the water heater to function properly.

Don’t forget about maintenance!

Tankless water heaters require routine maintenance to ensure that they continue to work well for many years. Depending on the quality of your local water, you can anticipate to clean your water heater every 12 to 24 months on average. Snowmelt is used by one water firm in the region to provide water that is virtually completely free of contaminants. Another water provider, on the other hand, relies on groundwater, which is frequently contaminated with minerals that might be damaging to a home’s plumbing system.

Rinnai licensed installers performed my first flush to confirm that the water heater was properly installed and running as it should have been.

Fortunately, my water heater was operating well and was not excessively clogged with mineral deposits.

The presence of blue vinegar indicates that calcified minerals have been flushed from the water heater’s exterior. I want to try the flushing process myself the next time because the video below was really helpful on the procedure.

A word on saving money…

Water at the highest costly category I’ve seen here costs around $0.01 per gallon, according to my calculations. It takes approximately a nickel’s worth of water to get my shower to start warming up. Over the course of a year, I save $15-$20 in water per shower. Because it’s more difficult for me to track my gas consumption, I’ve had to rely on averages. On average, a tankless water heater consumes 78 percent less energy than a conventional water heater. In my area, that equates to around $135 dollars each year.

It won’t take long for the savings to outweigh the few thousand dollars more it would have cost to build the system.
