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

View MoreBoiler size describes the heat output of a boiler in energy units, not the physical size of the boiler. Manufacturers measure boiler output in British thermal units (BTUs) per hour or boiler horsepower (BHP). BHP measurements usually only apply to very powerful and large capacity boilers, since one BHP equals 33,475 BTUs per hour.

View MoreWhen steam is manufactured in the boiler, it races out of the boiler into the piping system and towards the radiators. As it does, it encounters the cold pipes that cause the steam to condense back into water. During this condensing process, the steam gives back the latent heat it received in the boiler. In a steam heating system, this is what
