Question: Does hard water affect heater performance? what to do in hard water area

Reason：

Yes, hard water affect performance of heater.

Hard water results in formation of scale deposits when heated. The result will be reduction of heat transfer through the layers of scale; and water will take more time to heat and the element can also fail earlier than it rated life.

Solution：

Set the temperature to a lower setting below 50°c, scale forms will be more when water is heated above 50°c. Reducing the temperature will reduce the scale formation and avoid problems of energy wastage and element failure.
