How to Maintain Your Tankless Water Heater for Optimal Performance

Tankless water heaters are a popular choice for homeowners looking to save money on their energy bills and enjoy a constant supply of hot water. Unlike traditional water heaters, tankless models heat water on demand, which means they don't have a storage tank that needs to be constantly heated. This makes them more energy-efficient and cost-effective in the long run.

However, like any appliance, tankless water heaters require regular maintenance to ensure they continue to function properly. In this blog post, we'll share some tips on how to maintain your tankless water heater for optimal performance.

1. Flush the System

One of the most important things you can do to maintain your tankless water heater is to flush the system regularly. Over time, minerals and sediment can build up inside the unit, which can cause it to work less efficiently and even break down.

To flush the system, you'll need to turn off the power and water supply to the unit. Then, connect a hose to the cold water inlet valve and run it to a drain or outside. Open the valve and let the water run through the system for about 30 minutes. This will help to remove any buildup and keep your tankless water heater running smoothly.

2. Check the Pressure Relief Valve

The pressure relief valve is an important safety feature on your tankless water heater. It's designed to release pressure if the system becomes over-pressurized, which can happen if the temperature or pressure settings are too high.

To check the pressure relief valve, turn off the power and water supply to the unit. Then, locate the valve and lift the lever to release some water. If water doesn't come out or the valve is leaking, it may need to be replaced.

3. Inspect the Venting System

The venting system on your tankless water heater is responsible for removing exhaust gases from the unit. If the venting system becomes blocked or damaged, it can cause the unit to malfunction or even become dangerous.

To inspect the venting system, turn off the power and gas supply to the unit. Then, check the vent pipe for any signs of damage or blockage. If you notice any issues, it's important to have them repaired by a professional.

4. Check the Air Filter

The air filter on your tankless water heater helps to keep dust and debris from entering the unit. If the filter becomes clogged, it can cause the unit to work less efficiently and even overheat.

To check the air filter, turn off the power to the unit and locate the filter. Remove it and inspect it for any signs of damage or clogging. If it's dirty, clean it with a soft brush or replace it with a new one.

5. Schedule Professional Maintenance

While there are some things you can do to maintain your tankless water heater on your own, it's also important to schedule professional maintenance on a regular basis. A professional technician can inspect the unit, clean it, and make any necessary repairs to ensure it's working at optimal performance.

In conclusion, maintaining your tankless water heater is essential for optimal performance and longevity. By following these tips, you can keep your unit running smoothly and enjoy a constant supply of hot water for years to come.
