In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I live in Boston, MA and am planning to covert from oil to gas. Have had three contractors come in and am concerned they are recommending over-sized boilers. The local utility offers deep discounts and rebates on the Burnham Alpine line. The utility offers the 80, 105 and 150 Kbtu models.
Each contractor has recommended the 105, but I'm still concerned they may be over-sizing since over-sizing appears to be a common problem.
None of the contractors I've talked to has been wiling to do a Manual J calculation. Am I asking the wrong question? Should I be asking simply for a "heat-loss" calculation? One of the three did measure the radiators and count sections. The other two just eye-balled the house. It's a 1200 sf, single-family home built in 1926, frame construction. Walls had insulation blown in maybe 20 years ago; windows are original windows but with storms.
How do I figure out if the Alpine 105 is oversized for my house?
