How do I know how many watts my water heater is?

To calculate the wattage requirement to heat steel, use the following equation:

  • Watts = 0.05 x Lbs of Steel x ΔT (in °F) / Heat-Up Time (in hrs)
  • Watts = 3.1 x Gallons x ΔT (in °F) / Heat-Up Time (in hrs)
  • Watts = 165 x Gallons Per Minute X ΔT (in °F)
  • Watts = 1.35 x Gallons x ΔT (in °F) / Heat-Up Time (in hrs)
