How to Clean and Maintain a Tankless Water Heater
A tankless water heater, also known as a demand-type or on-demand water heater, is a more energy-efficient option for heating water in your home. Unlike traditional tank water heaters, tankless water heaters heat water as it is needed, rather than storing it in a tank. However, to keep your tankless water heater running efficiently, it is important to clean and maintain it regularly.
Here is a step-by-step guide on how to clean and maintain your tankless water heater:
- Turn off the power or gas supply to the water heater. Before you begin cleaning your tankless water heater, it is important to turn off the power or gas supply to the unit to avoid any accidents.
- Flush the water heater. To flush the water heater, turn off the cold water supply and turn on a hot water faucet. Use a garden hose to flush the water heater for about 5-10 minutes to remove any debris or sediment that has accumulated.
- Clean the inlet and outlet pipes. Use a brush and vinegar solution to clean the inlet and outlet pipes of the water heater. This will remove any buildup and help to improve the efficiency of the unit.
- Clean the air filter. If your tankless water heater has an air filter, it is important to clean it regularly to remove any dust or debris. Simply remove the filter and wash it with soap and water.
- Check the pressure relief valve. The pressure relief valve is a safety feature that prevents the water heater from overheating. It is important to check the valve regularly and make sure it is functioning properly.
- Check for leaks. Inspect the water heater for any leaks or damage. If you notice any leaks, it is important to have them repaired immediately.
- Check the gas combustion. If your tankless water heater is gas-powered, it is important to check the gas combustion regularly. A professional should perform this task as it involves analyzing the exhaust gas and making sure the combustion process is safe.
Regular cleaning and maintenance of your tankless water heater is essential to ensure that it runs efficiently and lasts for many years. The above steps will help you keep your tankless water heater in good working condition. However, if you are unsure about any of the steps or if you notice any problems with your water heater, it is best to contact a professional for assistance.
