You may wonder why a tankless water heater needs any maintenance since it has no storage tank. The culprit is hard water – and San Diego has plenty of that! Hard water is loaded with minerals like calcium and magnesium. Over time, these minerals can plug up the passages where water flows which affects water flow speed. This makes the water heater work harder to deliver hot water and water temperatures may fluctuate. This buildup can shorten the lifespan of the water heater and increase your energy bill.  In some cases, the heat exchanger or even the entire unit may need to be replaced.

A high water temperature setting can increase the risk of scale buildup. Heat makes chemicals dissolve faster, and so minerals will build up faster around the heating elements.
