i want to build a small greenhouse around my outdoor boiler..I was hoping to use one or two of those chimney fan driven heat exchangers to help capture some of the waste heat. Ive got to say that my boiler chimney looks like Saturn 5 launch vehicle upside down, with the amount of heat comign out of it. I also expect that there is some residual heat comign off the boiler and chimney.
I figure that raising the ambient temperature around the boiler by at twenty or thirty degrees should improve the performance of the boiler also.
Phase one will be a frame and roof, to just cover the wood, and then phase two will enclose the greenhouse portion..and I would insulate it with a thin layer of spray foam.
Has anyone experimented with a building around thier outdoor boiler?
