How Often Should You Service a Tankless Water Heater?

Most manufacturers recommend annual maintenance. Homes with hard water may require more frequent service to prevent excessive scale buildup.

You may need maintenance sooner if you notice:
  • Reduced hot water output
  • Fluctuating temperatures
  • Error codes
  • Increased energy usage
Preventative service is far less expensive than emergency repairs.
