Looking for some ideas for a friend as to pros and cons of different heating options. They have someone in the house on oxygen who can't handle smoke from a traditional woodstove. Any recommendations? He'd like some ideas of efficiency, cleanliness, ease of use, etc. I'll send this thread along for him to follow and maybe he'll jump in with some other questions once the discussion gets going. Thanks in advance! BTW, he's in CT so some sources would also be helpful if anyone knows of any.
