Hard Water

Hard water carries dissolved calcium and magnesium. When heated, those minerals drop out as scale and sediment.

Much of Central Ohio has moderately hard to hard water. In tanks it builds sediment that causes rumbling and lost capacity; in tankless units it scales the heat exchanger and must be descaled on a schedule.
