Yes, Your Tankless Water Heater Needs Maintenance

You’ve heard of air conditioning maintenance and you may have even heard of water heater maintenance. But did you know that your tankless water heater needs annual maintenance just like a traditional tank water heater does?

If you don’t schedule maintenance for your tankless water heater, you may be left calling for water heater repair in Roanoke, VA, instead. Keep reading to learn more about how you can stay ahead of tankless water heater repairs by prioritizing maintenance each year.

Reasons for Maintenance 

The top reason for scheduling maintenance for a tankless water heater is to reduce the chance of repairs. By the time your tankless water heater begins to show signs that something is wrong, the problem is already very far along. 

It may be a more costly and involved repair than if you scheduled maintenance and find a problem very early. Plus, investing in maintenance helps you prevent a scenario where your tankless water heater stops working completely and you are left without hot water at your house. 

Flushing the System

During a maintenance appointment, one step we will complete is flushing out your tankless water heater. The lines and components in your tankless water heater are much smaller than that in a more traditional tank water heater. Because of this, smaller problems can have a greater impact.

For example, if you have hard water that is high in mineral content, those minerals can build up in a tankless water heater much faster than they would in a water heater tank. 

Scheduling a tankless water heater to be flushed on a regular basis helps to ensure that your tankless water heater won’t have any clogs blocking water flow or heating ability. Usually, we suggest a tank water heater be flashed once per year, but your tankless water heater may need the service more often than that if you have very hard water. We can make a recommendation after inspecting the appliance. 

Cleaning Filters

The next step during a maintenance appointment is to clean out the two filters in your tankless water heater. The first is an air filter. Your gas-powered tankless water heater relies on a strong stream of air to help produce on-demand heating. If this air filter gets dirty, it could block airflow into the system.

The same thing goes for the water filter. The water filter helps to eliminate larger particles of debris, and even some of the minerals from hard water. But as the filter fills up, it can block water flow coming into your tankless water heater. As a homeowner, you can complete these cleaning steps for the filters yourself as well. If you’re not comfortable with how to clean out these two filters, our team can walk you through them during a maintenance appointment.

Checking Connections

Our final step during tankless water heater maintenance is to check all of the connections and make sure that they are secure. We may turn on the hot water at one or more sources inside your home to check that everything is working as it should. If we notice any concerns, we will bring them to your attention and offer a solution.

We can help you make the best choice for your tankless water heater. Rely on the experts at W.C. Butler Heating and Air Conditioning and schedule an appointment today.
