We are replacing our old boiler with a new one. We have received two different quotes. One for a Carrier 82% AFUE Model BWB 140,000 BTU and one for a Crown Boiler Aruba 4 model AWR105 105,000 BTU. We did some checking and determined we need about 80,000 BTU. So both boilers would be sufficient. Our house is 101 years old, 4 levels with an attic and full basement and about 1600 square feet. We live in Wisconsin about 4 blocks off Lake Michigan.
We are trying to determine if one of the brands is better than the other? I checked some consumer reviews and got conflicting information. The second question is do we need the additional BTU or is that just a waste?
