Well I had planed on buying a pacific energy super insert as I was told that it would fit my current fireplace but after I got to the shop to pay for it the guy tells me its too big and he recomends that I get the enerzone 1.8 cu ft insert. Anyways I decided to go ahead and order that and after I get home I start thinking to myself damn I hope its big enough to heat the house. My house is a split level 1200 sq ft home. Do you guys think this insert will be enough? Also I tried to do a search to find out reviews for that stove but didnt find anything, anyone familiar with that stove or even that company?
