3 Ways to Calculate BTU Per Square Foot - wikiHow

Jun 30, 2020 · Central air conditioning units frequently have the capacity coded into the model number; for example, model RDR36 would be a 36,000 BTU unit. They may also report their size as tonnage, with 12,000 BTUs equal to 1 ton (the amount of power needed to melt 1 ton of ice in 24 hours); thus the model RDR36 would be a 3-ton unit.

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.
