Why is my hot water heater using so much electricity?
Sediment Buildup
When the water heats up, minerals drop to the bottom of the tank and settle there. Over time, sediment can cover the lower heating element, reducing the efficiency of the hot water tank. It requires more electricity to heat the water when the lower heating element isn’t working properly.
