I bought my 25-pdv a little over 2 years ago to heat my 1600sq foot two story house. I have not ever been able to get it warm in here at all. I see about 58-60 degrees and that is in the room that the stove is. The stove seems to be burning pretty well, I just don't get it. I read on here that people are able to heat there homes to 70 degrees no problem. I have tried running the stove on hotter settings but it dosen't make much difference other then eating pellets.
