Your water heater has a dirty little secret.

All water heaters come standard with a fundamental flaw: the metal heating element will rust, scale and eventually fail. But not before it creates sediment inside the same tank that stores your family's hot water.

Heatworks water heaters are different. We use water as the heating element, so the hot water you get is purer. And requires no maintenance.
