Listen to the reviews on here, the one good I believe got flamed on the site, that unit to me is flawed, no different than a lemon car except it's all of them, I would not want that in my house for sure, I run an Econburn 100 boiler that is in my garage, it has some smoke spill issues at times but some of that is due to my chimney, I wouldn't want it in my house even with a better chimney. I grew up with freestanding stoves, then a Johnson energy wood furnace, first rented house had an old stove in it, all heated ok but made a mess, I built a furnace and a boiler, both worked well but none of the above ever had the issues that members on the other site talk about. I personally would not want something that somewhat randomly "backpuffs" as its being called, more like blows up like a pro stock diesel tractor does out the exhaust, anywhere in a house my family or I was living in.
