Can some one explain how electric heater works?
An electric water heater uses a heat element to convert electrical energy into heat energy. For every watt of electricity used, 3.414 Btu’s of heat are added to the water. All electric water heaters are 100% efficient but some have better insulation than others so that the heat in the water does not escape as fast as it does from lesser insulated water heaters. The old tank type electric water heater is great for the electrcial grid because it slowly heats the water over time and can have a device added to cut it off during electic peaks (since it has several gallons of hot water stored in it, it can provide heated water for a lenghty period during the day and then re-heat the water later in the night when people are not using electricity for other uses).
