Unfortunately my father passed away earlier this month. One of the things he left me was his house. The house needs work, but is in a much better school district than the one I live in now. The wife and I have decided to rehab his house and then sell our current home. When I was young, there was a forced hot air furnace in the house. When that furnace went (I'm guessing around 1980.) my father put a coal stove in the basement and ran what I believe is a 7X12 masonry chimney up the back of the house. It's a regular coal stove that he had fabricated a bonnet for and he successfully heated the house for years. He incorporated some cage fans into new ductwork to move more air. The stove and chimney are still there, but the bonnet is long gone. I still have a few shovels full of coal in the old bin though. The rest of the ductwork he installed minus the bonnet is still there also. I plan on lining and insulating the chimney. Oil prices must have come down (and he warped the coal stove) because he then installed a boiler around 15 years ago. He was planning on dropping the oil and going natural gas with the next boiler but the thing quit just as winter was starting last year. He was stuck with oil and purchased a new energy star 85% effficient boiler. So here I am with a new oil boiler, an old coal stove, and a quest to keep the baby due Nov 5th and wife as warm as possible for as cheap as possible. I don't expect to be done rehabbing the house until spring, but may be.... I have the original hot air ductwork that would take minimal work to get functional again. I have a different set of duct work from the coal stove that also would be easy to get operational again. I have a fully functional boiler that burns expensive black stuff. I was looking at the Englander 28-3500 as a stand alone when I noticed that it wasn't EPA certified and after burning an EPA stove I really don't want to go back. I like clean(er) chimneys and moving less wood. I sweep my current chimney from the bottom and really can't do the same with this one. I don't want to be climbing the roof when it's iced over. Is there anything like the 28-3500 that is EPA certified? The house is fairly small, about a 1K square feet cape in it's current state. It'll pick up another 500+ or so when I finish off upstairs. The house will be fairly well insulated when I get done also. Matt and a little overwhelmed at the moment, but determined to finish one thing at a time.
