As nice and convenient as tankless water heaters are, they are still subject to some of the same issues as other types. This leads to the need for periodic maintenance in order to keep them operating at their peak. The good news in this is that periodic maintenance really just boils down to one set of actions, once each year. 

A tankless water heater that is being used in an area where there is hard water and is set to a high temperature should be maintained about twice a year. Fortunately, regardless of your water heater’s maintenance needs, the actions that are needed are the same. What follows are a few ideas for Tankless Water Heater Maintenance and Inspection.

Flushing

Every water heater should be flushed periodically. This is one of the most basic maintenance actions that a homeowner should perform on their water heater. Over time, even a tankless water heater will accumulate minerals and other types of hard substances in the water chamber. This is especially true in areas where there is hard water. The material buildups in a water heater’s chamber can be very significant over time. Not performing this maintenance will cause performance issues and eventually affect the lifespan of your water heater. One of the most significant problems that can happen inside the water chamber is the build up of lime deposits, which is often not covered by the product’s warranty.

Lime buildups can be removed by using white vinegar, a sump pump, and two pieces of hose. With the hoses attached to the valves and the pump running the vinegar through the chamber, lime buildup should be a thing of the past. There are usually instructions on how to perform this maintenance with the materials that come with your water heater, but if there are none and you don’t feel confident in doing this yourself, call a plumber.

Clean the Water Filter

Some tankless water heaters come with a filter that will trap a lot of the debris that tries to get into the tank. These filters are excellent for helping to prevent these problems, although you still need to maintain your appliance as described above. By making sure there is a water filter, you will see a significantly cleaner water tank and it will be far less work for you the next time.

Once you remove the water filter of all the sentiment and debris, it will help to keep your water tank clean and it will improve your unit’s performance. Before you do this, make sure the unit is turned off. The filter should be cleaned by passing it through running water and wiping it off with a clean rag. If you don’t know where the filter is or can’t find it, look in the user’s manual or call a plumber for help.

Clean the Air Filter

Every tankless water heater comes with an air filter to ensure a good flow of air through the unit. This air filter should be cleaned periodically for the same reason that a water filter is cleaned, to ensure that debris is removed and air can flow freely. Cleaning the air filter is best done with a soft bristled brush and a soap and water solution. After any debris is removed, it should be allowed to dry before it is replaced in the unit.

By following the guidelines above you will be contributing significantly to the lifespan of your water heater. If you don’t feel confident about performing this maintenance, call a plumber, who can do it for you. Besides a cleaning and performing maintenance on your water heater, a plumber should be called and allowed to perform periodic inspections on your water heater. By doing this, a plumber can check valves, heating elements and pipes to make sure they are in proper working order. Any parts that are found to be broken or worn out should be replaced immediately. This is best done by a professional plumber, who can add significant life to your water heater by doing so.

K. Bernardo

We’re first time home owners and needed help with some plumbing and adding a filter system. They were able to get a technician scheduled to our house within a day or so of me contacting them. Mike was super helpful and was able to complete all the jobs in a timely manner, and also cleaned up the areas he was working in. Overall a great experience and would definitely use them for future jobs.

Nick Boudreux

Had a well pump that was shorting out and pretty much had no water. Adrian from this company not only got out next day but was great to work with. He was very friendly and knowledgeable I would definitely recommend this company to anyone that needs work done! Thanks again guys!

D. Marchand

I cannot say enough about this company!!! Their only concern is that you are up and running again with no worries. I’ve had Kyle the plumber, and Josh their electrician out here and both are polite, well trained and you can tell they truly care about getting you back in service. Great service, well trained caring staff! I will never go anywhere else!

S. Baraket

Never used Paul The plumber company before but I’m glad I did. Very courteous, professional and pleasant from the answering service (Diane) to employees (Jeremy). They diagnosed the problem and fixed it in no time. Very happy and satisfied with their service. Definitely will use again. Thank you

J. Wojo

DJ from PTP was incredibly helpful and knowledgeable. My shower was not draining and it became a bigger project than I thought it would and they came out quickly and were able to fix my problem. Then when my water heater had a slow leak they came back out quickly to attend to it and fix my problem. I really appreciate their hard work. Thank you so much!! Would definitely recommend them.

W. Chepren

I made an appointment on line the morning of July 31 and two trucks showed up at 1:00 pm right on time that same afternoon. Both guys were friendly and very knowledgeable. They quickly found the source of the wet patch on my ceiling which wasn’t the plumbing but a problem with the shower curtain. This is the second time I have called Paul. Both times I got outstanding service and will always call on Paul the Plumber for any plumbing problems in the future. Very reasonable cost for the visit.

H. MacPherson

I would recommend Paul the Plumber 100%. They offered same/next day service. They were friendly, professional and quick – from the office staff to the technicians. Overall an amazing experience from start to finish.

M. Richdale

Thanks to Mike Vallee from Paul the Plumber for responding to this new customer’s call so quickly. He was courteous, thorough, explained the repair he was doing and left the work area spotless. I highly recommend Paul the Plumber (and Mike!) to anyone looking for a reliable plumbing company.

D. Weaver

What a fantastic business. Helped us work with our water district in resolving meter replacement issues. They also fixed a pipe leak that had developed over time. Caleb was wonderful and answered our questions as well as working with the water district engineer on the meter issues. So easy to work with.

K. MacCallum

First time customer, and am very pleased with the whole experience. The highlight was definitely with the technicians assigned to the job and their work – Tyree and Corey were clean, polite, well-informed, and very helpful with some of the questions I had along the way. Their work appears to be top-notch, and they made sure no mess was left behind. Will definitely be calling and requesting these two again on any future needs.

S. DesMarais

Josh was amazing. He was able to install my ring doorbells with no issues. He also did a great check of my homes smoke detectors and a few electrical plugs. He was thorough, Knowledgeable, and easy to work with. I would definitely use them again.

D. Lefort

Arrived as scheduled to fix a leak from the shower valve. Tried to fix old 30 or 40 year old unit but had to replace with a new one. Quality work, parts and cleaned up when they were done. Would definitely use again.

V. Vincze

We had an issue with our water…too hard, calcium deposits, and very little pressure in our master bathroom shower only. The techs (Mike E. & Tyler S.) arrived right on time. They were friendly and very personable. After installing our whole house filtration system and successfully finding the issue with our master bathroom, they left the work areas in pristine condition. They were meticulous in their work, and I highly recommend them for any plumbing needs!

Michele

I’ve used Paul the Plumber twice now for electrical issues and they have been wonderful each time. They are fast, polite, knowledgeable, and very fairly priced. They explain everything well and answer my questions thoroughly and I feel safer now knowing what was causing my electrical issues and having it fixed! I will be using Paul the Plumber for all my household needs going forward

J. Shea

John was wonderful. He found the problem right away and fixed it. He checked other outlets just to make sure I would be safe. He explained different programs the company offers also. I’m very happy.

T. Minasian

These are the after photos of the Rinnai tankless water heater installation and vent to the outside. It was important to me that the crew was able to use the existing vent hole to the outside to run both the intake vent pipe and the outside vent pipe. It made the job very clean and did not change the appearance of the outside wall. A shout out to Mike E, Caleb, Josh & Corey
