Tankless water heaters have become more popular in recent years because they are energy-efficient, durable, and provide hot water on demand. They are a great investment for any homeowner who wants to save money on their energy bill and never run out of hot water. However, like any appliance in your home, a tankless water heater requires maintenance to function properly. In this blog post, we will discuss the importance of maintaining your tankless water heater and provide some tips on how to keep it in good condition.

Regular Cleaning

One of the simplest maintenance tasks for tankless water heaters is regular cleaning. Over time, minerals from the water can build up on the heater’s internal components, reducing its efficiency and lifespan. To prevent this, it’s recommended to clean your tankless water heater at least once a year. You can use a descaling solution or vinegar to remove the minerals from the heating element. Make sure to follow the manufacturer’s instructions when doing this task.

Check the Air Intake Filter

The air intake filter is an essential part of your tankless water heater as it prevents debris and dust from entering the appliance. You should check the filter regularly, at least once every six months, and clean or replace it if it’s clogged. A dirty air filter can cause your heater to work harder, leading to higher energy bills and decreased performance.

Inspect the Water Inlet and Outlet Valves

The water inlet and outlet valves control the flow of water into and out of your tankless water heater. These valves should be inspected for any leaks or signs of wear and tear. A plumber can check the valves and ensure they are in good condition. If there are any issues, the plumber will replace them promptly.

Schedule Professional Maintenance

Professional maintenance is crucial for your tankless water heater as they can spot issues before they turn into costly repairs. Plumbers have the expertise and equipment to perform in-depth inspections, and cleanings, and ensure your water heater runs smoothly. It’s recommended to schedule professional maintenance once a year, and the plumber will check for any issues with the gas line, electrical connections, and other components.

Keep the Area around the Water Heater Clear

Finally, it’s important to clear the area around your tankless water heater. Make sure there are no flammable materials or obstructions that can interfere with the heater’s performance. This tip is especially important if you have a gas-powered tankless water heater. If you notice any smells of gas or signs of a gas leak, turn off the gas immediately and call your plumber.


Maintaining your tankless water heater is essential if you want to enjoy years of uninterrupted hot water. Regular cleaning, checking the valves, scheduling professional maintenance, and clearing the area around your water heater are some of the ways to keep it in good condition.
