Tankless Water Heater Maintenance Tips for Optimal Performance

Leaks are not just annoying; they can spell severe structural problems for your tankless water heater. Check your unit for signs of moisture, then consult a plumber for the best solution.

Inspect your unit’s air intake filter periodically. This primary screen prevents debris from entering the system and keeps it working efficiently.

Check the Pressure Relief Valve

The pressure relief valve prevents explosions by releasing excess pressure from the tank. Testing this valve periodically is essential to ensure it is working correctly. To do this, turn off the water supply to your home and remove the cover on your tankless water heater. Position a bucket underneath the discharge tube. Then, open the valve by lifting the lever. If water flows into the bucket, your valve is working correctly. If you don’t see any water flowing out of the tube, the valve might need to be replaced.

While testing the pressure relief valve, inspecting your tankless water heater for signs of leaks or rust is also an excellent time. In case you detect any problems, it is recommended that you contact a plumber right away to fix the issue.

Having your tankless water heater flushed at least once a year is also a good idea. Flushing helps to remove any mineral deposits that may be clogging the heat exchanger, improving performance and prolonging the lifespan of your unit. In areas with hard water, this should be done more frequently. A pro can help you determine the best schedule for this routine maintenance, including insulating the tank and exposed hot water pipes to reduce energy loss and save money on your heating bill.

Inspect the Venting System

Tankless water heaters need to have a venting system to release exhaust gases. This venting system must be free from obstructions to ensure optimal performance and safety. The vent pipe should be checked regularly for obstructions, and birds nests, leaves, and other debris should be removed as they build up. The fan motor and filter should also be cleaned to minimize energy waste.

If your water heater produces discolored water or an unpleasant odor, it may indicate mineral buildup in the heat exchanger. Using a water softener can aid in reducing these deposits and extend the lifespan of your Dallas tankless water heater.

Leaks should also be addressed promptly, as they can cause severe damage to your home and lead to costly repairs. If you see pooling water or dampness near your tankless water heater, it is likely time to call in a plumber.

In some cases, the tankless water heater may need to be flushed. This can remove sediment and rust from the heat exchanger, improving water quality. You should consult the manufacturer’s instructions for flushing your unit. This typically involves shutting off the power and water supply, connecting a hose to the flush valve, and opening the gas valve to allow the unit to flush for several minutes.

Clean the Exterior

Inspect the area surrounding your tankless water heater regularly. The area must be free of obstructions, including snow and ice, that could block airflow to the unit. If you live in a coastal region, you may need extra maintenance as salt air from the ocean can be corrosive to your unit.

Cleaning the pipes leading to and from your unit is another crucial part of tankless water heater maintenance. This includes the venting system, heating elements, and pipes. Keeping these pipes clean helps ensure that your system is running efficiently and that there are no clogs or leaks.

You should also clean the air intake filter on your tankless water heater regularly. This filter prevents dust and insects from entering your system. Most tanks have this filter located between the venting system and the fan. Depending on your unit’s user manual, this may be as simple as removing the filter, rinsing it with water, and then drying it.

Check the Water Temperature

Tankless water heaters can save energy and money on utility bills. But, like all appliances, they require maintenance. This is important to keep them in good condition and prevent unforeseen complications in the future. This includes checking the temperature, cleaning the exterior, and flushing the system. The best way to do this is by having a professional inspect and service your tankless water heater.

It’s essential to check the temperature of your water heater regularly to ensure it’s heating at the correct temperature. If not, the temperature could be too high or low, leading to scalding and insufficient hot water in your home. You can quickly check the temperature by turning on a home faucet and waiting a few minutes. Then, turn off the faucet and look at the digital screen to see if it’s showing the right temperature.

Your tankless water heater should be flushed at least once a year to remove any sediment that builds up inside the unit. This is particularly important if you have hard water in your home, as minerals can damage the heat exchanger and increase energy costs. It’s also worth considering fitting your home with a water softener to reduce mineral deposits.

Lastly, the air filter on your gas tankless water heater should be cleaned frequently. It can get clogged with dirt, insects, or other debris that hinders airflow and causes error messages or electrical problems. It’s typically a quick and easy process to clean the air filter by removing it, rinsing it off with water, drying it, and reinserting it into the unit.
