I have a customer with a 5 section smith/mills 20. oil fired. he wants to go natural gas. I went thru the house and measured all radiators and by using the info on this site, came up with a total of 648.86 sq.ft. of radiation. Its a big old 3 story house. What does this convert to in btus?

    I'm not a pro but,

    648.86 * 240 = 155726 BTUs.



    Take that and add a 1.33 pickup factor and your at 207116 BTUs.  Use the DOE heating capacity rating on the boiler for this.  This would put you in the market for someting like a Burnham IN8.



    This will not be enough if the piping is oversized or uninsulated.

    Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.
