Once the water is at 100 Â°C, still more energy must be added. This is given by the heat of vaporization, which for water is 2261 kJoules per kilogram. So, in the example, once the 1 kg of water. is at 100 Â°C, this amount of energy must be added to boil it: 1 kg * 2261 KJoules/kilogram = 2261 kJoules.
If you can make an estimate of how much hot water you use, you can then estimate how much electric power it takes to make the hot water, and then adjust for standby losses. If you use 45 gallons of hot water a day, and you heat the water from 50F up to 130F, then the energy to do this is:
