Tankless Water Heater Flushing

One of the most important elements in your tankless water heater is the heat exchanger, which has narrow water passages. Flushing your tankless water heaters whose heat exchangers can become blocked by the lime scale is very important and must be done on an annual basis before something goes wrong.

If you don't flush the water heater, the heat exchanger can be damaged as not enough water will pass through and cool it down. Any damage which is related to lime scale build-up is not covered by the warranty. Take care of your investment, call Reliance today.

FAQs

Q: What Is A Tankless Water? 

A tankless water heater heats water only when there is a demand for it. Traditional tanked water heaters constantly work to heat water, producing standby heat loss, which can be costly. When hot water is turned on at the source, cold water travels through a pipe into the tankless unit. In a gas-fired tankless water heater, a gas burner heats the water. As a result, tankless water heaters supply a constant flow of hot water.

A: Under normal use, Tankless Water Heaters should be flushed and descaled of Lime & calcium Scale at least once a years depending on usage and water quality.


Q: What happens if I don’t flush regularly?

A: The heat exchanger can be damaged by a failure to flush. Regular flushing prolongs the life of your Tankless Hot Water Heater.
