I am still in debate on putting the Tarm in my deatached garage and piping it to my forced air system or putting in a Caddy furnace in my basement. The Tarm was installed in my parents house in 1980 it is a MB Solo I beleive but cannot find a model #. They used it for 2 seasons back then and had a chimney fire and never used it again. How much is this thing worth roughly if I was to try and sell it? It was unhooked a few years back when they upgraded the oil boiler to a new unit and is just sitting there waiting for me to lift up out the bilco doors. Any ideas on what I could get for this?
