I have heard that some install the HS tarm outside in a shed rather than in a basement. Is this possible? I have forced air gas now and am planning to put wood primary heat in this house over the summer.. I have seen the heat exchangers on Ebay for $200 or less. Without a good way to get the wood in this basement with out carring through the house and down the stairs outdoors is a good option that and if a fire occurs I burn down the shed and its contents rather than the house... If this is doable any ideas on costs? Probable do most of it myself with exception of heat exchanger. The Tarm is only 1 season used since 1978 in my parents basement so If I can get it out and use i here that saves a ton right there... Any thoughts?
