Hot water heater power usage watts
WebJun 16, 2024 · You would need a transformer with a 72 volt secondary rated at 8.5 amperes (about 600 VA). This would be connected so that the phase of the secondary was opposite of the mains phase (hence the term "bucking"), thus reducing the voltage to the element to 240 - 72 = 168 V. This would give you (168/240)^2 x 3000 = 1500 W. WebA 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 1,163 Wh/kg°C. V = volume of water to heat. deltaT = Th-Tc. Th = temperature of hot water. Tc = temperature of input cold water. PR = performance ratio (it includes losses of ...
