I have been toying with the idea of selling my Aquatherm but there is little interest in it. I have it going to a HX in the forced air furnace of my house and it also heats a 1000 sq ft kennel. Since I burn a stove in the house we hardly ever use the forced air so that is a round trip with little value. I was thinking of putting in heat in our insulated but electric heated basement using the OWB. It is already running into the basement so I don't think it would be too hard to get it to where we want the heat. What kind of a system would you put in for the basement. We plan on finishing the basement at some point so I don't think a noisy Hanging Modine would be the answer.
