Descaling a tankless water heater is the process of removing limescale and mineral buildup from the unit. Limescale is a hard, chalky deposit that can form on the heating elements and other internal components of the water heater, reducing its efficiency and lifespan. Descaling a tankless water heater is a relatively simple process that can be done with a few household items.
It is important to descale your tankless water heater regularly to maintain its efficiency and prevent costly repairs. Descaling can also help to improve the quality of your water and reduce the risk ofgrowth. If you live in an area with hard water, you may need to descale your water heater more frequently.
