Regular descaling:

Mineral buildup can affect the efficiency of your tankless water heater. It's important to descale your unit at least once a year to remove any sediment and mineral deposits that may have accumulated, especially if you have hard water.

Clean the air intake filter:

Dust and debris can clog the air intake filter in your tankless water heater. Regularly check and clean this filter to facilitate optimal airflow and proper functioning of the unit.

Inspect the venting system:

Keep the venting system clear of obstructions and properly sealed. This is done to prevent hazardous gas leaks and maintain efficient operation. Check for signs of wear or damage and replace the components as necessary.

Check the water inlet screen:

The water inlet screen can become clogged with debris and sediment. Regularly inspect and clean this screen to maintain a steady flow of water into the heating unit and prevent performance issues.

Monitor error codes:

Modern tankless water heaters often display error codes when something is wrong. Familiarize yourself with these codes and consult the manual to troubleshoot issues promptly.
