The Regency 5200 doesn't seem to be very different in size, output, etc. than the BK 40, and both have cats. Do you think it performs better in some way?About one third of the basement wall is insulated, and there is closet storage along about a quarter of the uninsulated wall. I remember your suggestion of a Regency 5200. I had looked it up then.
I'm thinking: If I would put a 6 inch hybrid insulated flexible liner inside the vermiculite-insulated 8 inch rigid liner, I would have an EXTREMELY well-insulated system, and I would need a stove that has a 6 inch exhaust. I'm reading on some of these threads that the BK Princess is less fussy about venting than the King 40, and it has a 6 inch exhaust. Of course it would require a higher temperature setting and shorter burn times and more frequent reloading to get the amount of heat that this King 40 normally produces, but I might eliminate the problem of condensation.
I know there are much less expensive large stoves at Tractor Supply, that are advertised to produce a lot of heat (rated for heating 3,200 square feet, producing over 180,000 BTU) but they don't hold very much wood (less than 50 lbs. ) and don't have good automatic thermostatic draft control, and would need to be watched and reloaded constantly. I keep coming back to Blaze King as the best overall.
