How do I calculate the power requirement for an electric boiler?

The basic formula used for electric boilers are as given below: 10 KW = 1 BHP (boiler horsepower) 1 KW = 3412 BTU/HR 1 KW = 3.48 LB/HR steam (from & at 212 deg. F.) Amp draw (1 PH) = watts / volts Amp draw (3 PH) = watts / (volts X 1.732) (N.E.C. requires service for 125% of amp draw.) 1 cubic foot = 7.461 gallons water 1 gallon water = 8.331 lb. Maximum water usage = .
