Alright guys. I've got a 2200 square ft house (1100 on top 1100 in basement) with a two car attached garage. My local cb dealer came by this afternoon and told me he usually recommends the 2400 but he thought the 1450 would be fine for our house. I told him someday in the long range future I might build a small barn to possibly heat but that would probably be along time. After he left I was thinking of maybe heating my attached garage for now though. So my question for you all. Will the 1450 heat my house and garage or should I go with the 2400? First year in this house. Not been a terribly cold winter but I figure I've used average of 5 gal of propane per day. Now that's heating house only and not attached garage. Thanks for the info!
