Tankless water heaters are an efficient and reliable way to provide hot water for your home. However, like all appliances, they require regular maintenance to ensure they continue to function properly. In this guide, we’ll explore the importance of tankless water heater maintenance, how to perform maintenance tasks, and when to call a professional plumber for help.
Importance of Tankless Water Heater Maintenance
Tankless water heaters are known for their longevity and efficiency, but they can still develop issues over time if not properly maintained. Regular maintenance helps to:

- Extend Lifespan: Regular maintenance can help extend the lifespan of your tankless water heater by preventing major issues from developing.
- Ensure Safety: Checking for gas leaks and other safety hazards during maintenance helps ensure your tankless water heater is operating safely.
How to Maintain a Tankless Water Heater
1. Regular Flushing
- Turn off the power and water supply to the unit.

- Rinse the unit with clean water to remove any remaining vinegar.
2. Check and Clean the Filter
