A 50 gallon 5 500 watt water heater with a 90 ef and an electricity rate of 16 per kilowatt hour will cost 781 to operate each year. Click calculate to find the energy consumption of a water heater using 4000 watts for 3 hours a day 0 10 per kwh. The graph above shows the way a geyser uses electricity. The instant geysers have the responsibility of delivering instant hot water at optimum temperatures.

The storage geysers consume 2 kw of power in the bargain. Water heater geyser electricity consumption. Calculator of energy and costs for hot water heater enter your own values in the white boxes results are displayed in the green boxes. If you heat 15 litres of water both the geysers will consume the same amount of power.
