About Boiler Horsepower

One boiler horsepower (BHP) ≈ 9,810 W = 33,475 BTU/h - the power to evaporate 34.5 lb of water per hour at 212°F, standardised by ASME for rating steam boilers. A small office building needs 10-50 BHP; a hospital or large plant 200-2,000 BHP. Critically, 1 BHP is ~13.1× larger than 1 mechanical horsepower (746 W) - a dangerous confusion when specifying heating equipment. 1 BHP ≈ 9,810.6 W.

About Kilowatts

A kilowatt (kW) is 1,000 W - the everyday unit for home, vehicle, and industrial power. Average US home consumption is ~1.2 kW continuous (~10,500 kWh/year). EV motors range from 30 kW (city cars) to 600+ kW (performance models); a Tesla Model S Performance produces 560 kW (751 hp). Industrial gas turbines on commercial aircraft generate 20,000-100,000 kW. Solar installations are sized in kW-peak. Industrial electric motors span from fractional kW to thousands of kW. 1 kW = 1,000 W = 1.341 hp = 3,412.1 BTU/h.
