I am in the process of buying a Lopi 1250 wood stove to heat an addition to our house. The installed prices I have been quoted run anywhere from $3100 to $4300. Does it make sense that there would be that much difference between vendors for the same product? Are there differences in installation between one company or another that I need to know? It seems fairly straightforward, just installing the stove in an existing fireplace and running the steel chimney up the existing brick one. I want to get the best price but don't want to cheap out to the point that I get an inferior installation. Thanks for anyone who can answer this question.
