Boiler Sizing Calculators | Powerhouse

The BTU/hour to Boiler Horsepower calculator is used to help size both steam and hot water boilers. This calculation translates the heat transfer input requirement to BHP. To do so, we divide the BTU/hour by a constant of 33,475. This constant represents water being converted to steam, which is 34.5 pounds of water multiplied by 970.3 BTU/lb
