New to the forum so please forgive my lack of terminology. We are restoring an 1980s house and there is an opportunity to replace the single face wood burning fireplace with a single or 2 or 3 sided insert. The insert is for aesthetic purposes as we are using a heat pump for heating. I’ve been reading about double sided hearths and I see a lot of negative comments about smoke smell and air conditioning. We can leave the hearth as it is but the wife likes the idea of a fireplace that can be seen from 3 sides. Can anyone here comment on the pros and cons of 1/2/3 sided inserts?
