I have a Vogelzang Mountaineer wood stove this is my 3rd winter heating with it. We had installed into an existing chimney that once was used for a wood stove. The stove seem to be okay the first yr. not great but okay. It is suppose to be enough for a 2000 sq. ft. house our house is only 800sq. ft and we are probably only heating 500 sq. ft. because we have all the doors closed to part of the house. The highest temp the house has been was 71 but normally it will only get to 69 and that is with 2 ceramic space heaters going if I take one of those out it goes down to 67. I have heard that you either get a good vogelzang or you get on that is worthless. I have tried to keep the damper clsed so the stove could retain the heat, but I have no way of adjusting the air flow. I live in S.W. Mo and it gets down to the single digits every once in a while but most of the time it is in the 30's and teen's. I think that it should be doing a better job than it is. I know my house is 85 yrs old and has a few drafts in it the insulation is not that bad either, I have been in alot worse. What should I do just go out and by another woodstove. What brands would be good ? What should I look for?
