How to Descale a Tankless Water Heater

A tankless water heater is an energy-efficient option for providing hot water on demand. However, like any appliance that heats water, tankless units can accumulate mineral deposits over time, especially in areas with hard water. These deposits, mainly composed of calcium and magnesium, can reduce the efficiency of your heater and even cause damage. Descaling is an essential part of annual tankless water heater maintenance that helps prevent these issues.
