Water Heating Calculator for Time Energy and Power

The heat capacity Cp of water is 4186kJ/kg-C T = 80-20 = 60 C So the energy required to raise the temperature of 7000 kg of water from 20C to 80C is: Energy E = mCpT = 7000 x 4186 x 60 = 1758120 kJ or = 488 36 KW Power = Energy / time And this is 48836 Kilo Watts of power (since 1J/s = 1W) 1758120 kilojoule/hour = 48836666667 kilowatt hour
