Explanation:

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)
