How To Properly Maintain Your Tankless Water Heater

Here are some tips for maintaining your water heater.

A tankless water heater is a big investment for your home, so you want to ensure that it lasts as long as possible. A tankless water heater can last up to 20 years with proper maintenance. Here are some tips on how to properly maintain your tankless water heater:

Flush the System Regularly

Like any other type of water heater, it’s important to flush your tankless water heater regularly. This will help remove any sediment that builds up over time and could clog the system. You should flush your tankless water heater at least once a year, but more often if you have hard water.

Use Descaling Solution

Descaling solutions can help remove hard water deposits built on the heating elements. This way, your tankless water heater can operate more efficiently. You can find descaling solutions at most hardware stores. Follow the instructions on the package, and make sure to flush the system afterward.

Replace the Anode Rod

Replacing the anode rod regularly will help extend the life of your tankless water heater. The anode rod attracts corrosion, so you’re essentially protecting the rest of the tank by replacing it. You should replace the anode rod every 3-5 years if it shows signs of wear and tear.

Schedule Annual Maintenance

It’s always a good idea to have your tankless water heater checked by a professional annually. They will be able to clean the system and ensure everything is in working order. If they find anything that needs to be fixed, the water heater repair technician can do it then and there. This will help prevent any major problems down the road.

Know the Signs of Trouble

Even with proper maintenance, there may come a time when your tankless water heater needs to be replaced. It’s important to know the signs that indicate it’s time for a new water heater. If you notice any strange noises coming from the unit or if it takes longer than usual for the water to heat up, these could be signs that the unit is starting to fail. If you notice any of these issues, it’s best to call a professional immediately.


Tankless water heaters are a great investment for your home. With proper maintenance, they can last for many years. By following the tips above, you can help ensure that your tankless water heater will provide you with hot water for years to come.
