Well my 10 yr old VC Intrepid II 1990 is just not worth rebuilding for the 3rd time. Need to heat a den area app 600 sq ft with a second level. Leave the door open to move heat towards rest of the house which I heat with pellets. The VC was just ok with 5 hr burns but maintenance as we know was a bummer! I did like the catalytic aspect as I got the longer burns. Looking for long slow low heat burns. Have much everything on the forums just concerned since I have used many stoves over the years but never soapstone. Looking for keystone owner comments.
