I live in a small carriage house (approx. 1350 sq ft) built in 1900 that I am in the process of renovating. There is an existing freestanding Montgomery wood/coal burning stove in the living room (see picture) that, from what I gather, has not been used for 10 or more years. I would like to replace it with a more efficient, cleaner-burning wood stove. (I am looking at the Lopi 1250 + 1750 but am open to suggestions.) I didn't think it would be a difficult job, however the guys that came to take a look last week seem reluctant to take it on or even to give me an estimate. I am pretty handy, I was planning to remove the old stove and the existing 'hearth' (fake bricks) myself, and now I am thinking of installing the replacement stove too, however I am concerned about using the existing set up. I don't know how long it's been since it was last used or cleaned, and I know nothing about how to check to make sure it is safe as is. Any suggestions? Thanks very much.
