One of the main selling points of a tankless water heater is that you typically never run out of hot water. This is true to a point. However, just like any other appliance, it needs periodic maintenance to ensure it operates at peak efficiency. Some procedures are similar to those of a conventional tank water heater, but there are generally fewer steps overall. Here are some helpful tips on maintaining your tankless water heater.

Clean the Air Filter

Not all tankless units have an air filter, but if yours does, then it should be cleaned about twice annually. Rinse it well, use a soft scrub brush if necessary, and then dry it. When the air filter is completely dry, reinstall it.

Clean the Water Filter

The water filter should be cleaned every few months to prevent debris from accumulating. Remove it, rinse it under running water for a few minutes, scrub it if necessary, and then reinstall it.

Flush and Descale the System

Once a year, the system should be flushed to remove any mineral deposits that may have accumulated. Descaling the system can be easily done by running a descaling solution through the system and then rinsing it with clear water.

Clean the Condensate Trap

Not all tankless units have a condensate valve, but if yours does, then it should be cleaned periodically. The cleaning interval varies by model, so check your owner’s manual for the recommended time interval.

Pressure Relief Valve

Both tank and tankless water heaters have a pressure relief valve that functions to keep excess pressure from building up. The valve should operate easily. If yours doesn’t, then you need to have it serviced or replaced by a professional.

Are All These DIY Projects?

We recommend that homeowners call a professional for many of these procedures. Some components, like the pressure relief valve, can cause severe damage if they’re not properly installed. Some maintenance can be completed with little to no risk, such as cleaning the water filter or the air filter.

If you notice leaks, a significant drop in performance, or hear unusual noises, you should call a professional to address them. These issues can require professional intervention that the average DIY homeowner may not be trained to correct.
