First thing this is a great site. I have learned alot here reading the forums since I joined up and now have decided to take the plunge and get a Central Boiler. Here is my situation. I have a 2200 sq ft cap cod home on a full basement here in northern michigan. I have hydronic baseboard heat and a 100 gallon boiler mate. I also have a 30 X 40 pole barn that is uninsulated that I may want to heat in the future after I insulate it. I really have no need to heat the pole barn all the time, maybe just when I go out there for what ever reason. The salesman said the 5036 would do everything just fine but if I wanted to heat the barn all the time the bigger model 6048 would do the trick. Do you think if I got the bigger model 6048 and I was heating my house only and hot water would I burn more wood than the model 5036? I would like to keep my options open in case I decide to run heat to my barn but If I do not will I be sorry with the 5036? Its probably a catch 22 situation here. There is a $1900 difference in price between the two. Your input would be greatly appreciated.
