Why is Tankless Hot Water Heater Maintenance Important?

Why is Tankless Hot Water Heater Maintenance Important?

How important is tankless water heater maintenance? As it turns out, maintenance to a tankless hot water system plays a large role in how it works and how much you get out of it. 

Longevity of Heater

Tankless water heaters  can last up to 20 years, significantly longer than a tank-style water heater. However, without maintenance, your tankless water heater may expire prematurely

Proper Function of Components

Limescale buildup left behind inside of the water heater can damage the components inside of the device, in particular the heat exchanger, heating elements, and gas burner.

Hard water , in particular, contains high mineral levels. When the water heats up, calcium deposits form. These deposits will cover the thermostat to the point that it can’t correctly register the water temperature, forcing the device to suddenly produce scalding hot water


The increased temperatures force the device to work harder, bringing down the energy efficiency of the device. If your device runs less efficiently than it should, you will end up paying for it in higher utility bills.

Hot Water Production

If the tankless system becomes clogged, it can also affect the flow rate or how much hot water it can produce. If the gallons per minute (GPM) generation doesn’t meet your household’s needs, it may create a cold water sandwich. A cold water sandwich means that you will get hot water surrounded by moments of cold water.

When Does Your Tankless Water Heater Need Maintenance? 

As a general rule, we suggest performing maintenance on your tankless heater once a year before the weather starts to turn cold. 

Different manufacturers may suggest performing maintenance more frequently or less frequently than most, so always go by the manufacturer’s recommendation.
