Hi, I live in Buffalo NY and am looking to put a woodstove in ourbasement and use it as our primary hear source. We have a 900 sq ft house, it is very well insulated and do have a natural gas furnance. My question is, what size should I be looking for. I went to a local dealer who recommened the regency f1100 and said that anything bigger would be too hot. Also in consideration was a Osburn 1600 which was a little bigger. I have read online that it is ok to buy a little bigger stove and just build a smaller fire in it but am not sure how accurate that is. Any help you can give is appreciated.
