in Gas Heating
I am in the process of converting the existing oil boiler which is U.S radiator Corp red Top size A6, model # 64479. I am considering  the Columbia MCB series gas boiler. would you recommend I go with 75,000 BTU or 100,000 BTU input. My town homes heating area has 7 radiators & is approx. 1,000 sq ft.

    Heat loss needs to be done

    Rad size and home soze doesnt dictate boiler size. Complete a heat loss calc and you will get you answer. Slant fin has a prettygood program.

    Have to calculate the heat loss of the structure. Then match the boiler according to that.If no one posts the link to the download of the calculator, I'll post it later, when I get home.
