How Often Does a Tankless Water Heater Require Routine Maintenance?

For a typical one to four-person household, a tankless water heater should be serviced every 8 to 12 months. However, commercial properties with higher hot water demand - such as restaurants, salons, laundry facilities, pet groomers, and hotels - may require maintenance every 3 to 6 months to keep their systems running efficiently.

Routine maintenance helps ensure your tankless water heater operates at peak performance, especially when dealing with hard water and high-altitude conditions like those we face here in Colorado.

Give Instant Hot Water Co a call today to schedule your tankless water heater maintenance and keep your system running strong.
