Energy Required for Water Heating | EGEE 102: Energy .
The life of the water heater is expected to be about 10 years. Use an appropriate cost for electricity and compare the operating expenses. Heat required (BTU) = m x C p x (Temperature Difference) Where C p is the heat capacity of water (1 BTU/lb/F) and m is the mass of the water (Assume 1 gal has 8.3 lb of water and the 3,412 BTU = 1 kWh) Solution:
