Ok guys here's my situation looking at getting a pellet stove to use as a primary heat source my home is 1200square foot two stories but I plan on putting it in my basement so I'll be heating 1800 square feet basement is 90% underground so once I get my stone foundation up to temp I should be alright I'm thinking. So for my questions. Am I right about that? Should I put vents with the built in fans on the first floor to suck the heat out of the basement? Can I even heat a two story house with these? My house is an open layout big living room and big kitchen then three bedrooms and a bathroom upstairs recently remodeled so insulation is good windows are good. Next set of questions I want to put this where my oil furnace is currently can I remove that and just hook the stove up to the existing pipeing that's going into the chimney now? I plan to put the clean air vent where the fill up pipes come out for my tanks but my main concern is putting the exhaust pipe into the chimney if I can just use my existing pipe that would be perfect. I'm looking mainly at used stoves or new under 1200$ preferbly a used one around 600 would be better. What makes should I look at what makes should I avoid? How many ton am I roughly looking at for a heating season in central pa (our house is usually set at 68) I know I kind of rambled and have alot of questions but found this forum and figured I'd give it a shot! I grew up on a hand fired wood stove as a main heat source so I'm savy on that but pellet stoves are a new animal to me. Any advice or direction will be greatly appreciated and thank you in advance
