How much electricity does a 150 liter geyser use?

Answer 1

It depends on the element size that heats the water. The average 150L geyser uses a 3kW element, which will take about 2.5h to heat the water from cold to 70'C. If you "empty" the geyser twice daily, which is an unlikely maximum, it'll use 15 kWh of electricity.

Answer 2

The electricity consumption of a 150-liter geyser depends on its wattage rating and the duration it operates. Typically, a geyser with a power rating of 2000 watts operating for one hour would consume 2 kWh (kilowatt-hours) of electricity. To calculate the exact usage, multiply the wattage by the operating hours and divide by 1000 to convert to kWh.
