Tankless Water Heater Service and Routine Planned Maintenance

Flushing, filter cleaning, and expert planned maintenance—plus fast help when you need emergency tankless water heater service.

Why Maintenance Matters

Required Maintenance for Tankless Water Heaters

The ease with which tankless water heater equipment is serviced and the lifespan of the equipment unit, with proper maintenance, contribute to the decision to purchase a tankless water heater. Maintenance for tankless water heaters varies by manufacturer and model, but typically a routine service every 18 months is sufficient.

However, the time between necessary maintenance depends on the water quality in your home and your usage, so always refer to manufacturer recommendations.

Tankless Water Heater Routine Maintenance

Routine planned maintenance helps protect performance, efficiency, and the long-term life of your unit.

Clean the In-Line Screen Filter

The in-line screen filter should be checked periodically for debris and cleaned to prevent buildup that will clog the filter and reduce performance.

Flushing

The unit should be flushed periodically to keep it free of scale and lime. Buildup of scale and lime, if left unchecked, will shorten the water heater’s lifespan over time.

Combustion Clean-Out (Non-Condensing Units)

A top-down combustion clean-out for non-condensing units should be scheduled every four years.

Plan Ahead

Schedule Service

Routine maintenance takes about two hours. Call, text, or reach out online—and ask about Blue Club priority scheduling.

I thought I was truly in a pickle when my furnace went out around the holidays, and I felt so ridiculous for not having had it serviced in the fall. But Jim got right back to me, and an expert technician came right out, listened to my questions and concerns, and came up with great solutions immediately
