what size boiler is needed per square foot of a house .

What Size Boiler Is Needed Per Square Foot of a House .

Boiler 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.

Making sense of boiler ratings - HPAC Magazi

Aug 16, 2017· For example, if we have a natural gas boiler with an input rating of 100,000 Btu/h and a heating capacity of 85,000, we would have a steady state efficiency of 85 per cent. This steady state can only be measured when the boiler is at full load and all the conditions, such as return water temperature, air temperature, air/fuel ration, and so on ...
