Possible to put boiler in fireplace opening?

e_berns Member Posts: 4
I am handy homeowner. I have periodically spent many hours looking at this site, so I know the expertise that is here. I have question which I hope someone here may know answer. I would like to install hydronic wall/baseboard heat (underfloor not possible) for an old farmhouse/cottage. I will hire professional help as needed. Living space is very limited, about 1400 s.f. total, to fit radiators or boiler. Current fuel source is propane although could consider other trucked fuel source. There is no piped natural gas here. In the farmhouse there is a fireplace with chimney in a location which would be very convenient to locate heat source. Does anyone know of a boiler that can be located in this opening and vented up chimney? There is currently a cast iron gas burning fireplace in the opening so it is not easy to measure the opening exactly but it appears fairly typical, 36" wide x 30" high. I would like to improve comfort and efficienty, but I don't want boiler that is ugly if very visible. Thank you for any assistance.

    All boilers are


    Seriously, the answer is: "That depends on the chimney."

    If you can put a 4-5" slinky down the chimney from the top all the way to the bottom (without any major off-sets or restrictions, you could connect a boiler thereto.
