calculation of hot water boiler system

hot water heater energy calculator : consumption of ...

Formula to calculate electricity or gas consumption of water heating . A simple formula to estimate the energy required to heat a volume of water is : E = C*V*DeltaT/PR Where E = energy in kWh C = Specific heat of water - 4.187 kJ/kgK or 1163 Wh/kg°C V = volume of water to heat deltaT = Th-Tc Th = temperature of hot water
