How to calculate the kW required to heat a volume of water

Sep 26, 2012 · To heat the same water volume in half the time (30 minutes) would need twice the heating power, ie, 7kW. Converesely, if we only use half the heating power, 1.75kW, it will take twice as long to heat up to desired temperature, ie, 2 hours. If we only have a 1kW element available, we will expect a heat up time in excess of 3 hours.
