Thinking of replacing my new insert with a bigger stove to heat the house instead of help my furnace. Who's got a soapstone ?? My house is a cape about 1600 sq ft and pretty well insulated. How even is the heat really ? My manufacturer claimed my stove would burn 8 hrs and it'll only go 3.5 choked all the way down packed tightly. I needed to more homework but that's another story and stove shop said this is the size I need to "heat" the house. I would like to get one with a rear flue collar so I can move it all the way out of fireplace.
