I live in MA, and am having an addition done. I have gas service and currently have a 12 year old Burnham 108btu burner to heat 1872 sq' of home through hot water baseboard, and a Bock 50gal hot water turbo-storr. The addition will be adding another 1178 sq', of which 450' will be by radiant, and the remainer by baseboard. I will also be finishing my basement, which will add another 1386 sq' for baseboard heat when finished.
I have one proposal to replace existin Burnham with a Buderus G234 boiler, with the modulation unit. Another proposal to replace the Burnham with a Weil-McLain Ultra230,which has the modulation. Another proposal suggests keeping the existing Burnham, and adding another in the addition to handle that area. I have also been trying to do my homework on these boards and see others recommend the Munchkins, Dunkirks, and Peerless. I would appreciate any opinions on those brands and what you might think would be the best based upon my specs.
Also, am having the Spacepack system installed, and a Comfortmaker AC unti was suggested. I have also heard of Armstrong, Carrier, trane, AMerican Standard. I guess I'm looking for around 11-12 SEER with scroll compressor. Any thoughts or suggestions?
Thanks in advance for all replies.
