### Boiler Heating Surface Area in Sq-Ft Vs. Gross Output BT

- ApplicationsOct 27, 2016· I believe that for residential size anthracite stoker boilers you can get a decent initial ballpark guess of their Gross BTUH output rating if you know their heating surface area in square feet, by multiplying the heating surface area in square feet by 7,500. Does this sound like a good first guess? Gross Output BTUH = 7,500 x Heating Area in Sq-Ft lexie@zozen.com > Get A Quote >
