Does anybody have any experience with the central boiler 5036 model. How much does the total installation cost? How much square footage can this model heat? I live in western md and I was wondering how many cords of wood I would go thru if I heated from october-march. Winters around here average in the 20's - 30's sometimes going down into the single digits. My house was built in 2009 so it's insulated fairly well. My house is approx 1650 sfq t and i would also be heating my basement which is also 1650 square feet. I would like to heat a garage and another building in the future so figure I would need another 2,000 square feet. Everything heated at once should be a little over 5,000 square feet. With that being said would the 5036 model do the job or do I need a bigger model?
