I have 3400 sq ft heated by two heat pumps / electric furnaces. This was our first winter in the house and we had electric bills as high as $610 with the thermostats set at 66F. We're in the woods and have lots of fallen trees and standing dead trees so next winter I want to add some wood heat. My plan is to install an add-on wood furnace in the basement to heat one side of the house (~2000 sq ft). There is a fireplace in the basement so I can use the existing chimney. I'm trying to decide what to buy. I went to Tractor Supply and Menards and looked at the Hotblast 1551 and the Shelter SF1000. The sticker price on each is $1400, but Menards always has the 11% rebate ($1246) and TSC is willing to take off $200 ($1200). The SF1000 has a smaller firebox (4 cu. ft. vs 5.2 cu. ft.) but moves more air (1500 CFM vs 1100 CFM). Reading the forums, I see complaints about the draft blower on the SF1000, and complaints about the automatic damper control on the 1551. Can anybody recommend one over the other, or suggest another option in a similar price range? Thanks in advance for any input.
