I have a 4,000 sq ft shop, a 4,600 sq ft house, also heating hot water tank and planning on 400gal hot tub to put in line this coming year, currently using an overwhelmed wood master 4400. I was planning on upgrading to a wood master 5500, 10,000 sq ft capacity, but considering I have access to pellets at a ridiculous price, wood master has a 1100 series pellet boiler, 8,000 sq ft capacity. I was told it would keep up easily, considering the basement, which is 1,800sq ft rarely gets any heat at all, but I was told it would use 6-8 40lb bags a day to heat the total area. That's 3-4 tonnes a month for 5-6 months a year. Does that sound right for my sq ft? Even though I can get pellets stupid cheap, sounds like an awful lot of pellets, especially if I add another boiler later on. Firewood is dirt cheap and plentiful, but I hate the storage area needed and the larger wood isn't the best for my back. A 5500 would do the trick, but I'm still stuck with wood. Pellets, easier to handle, way less storage needed, but that's a lot of pellets. Thoughts?
