Intent here is to utilized the galvanized pipe as means of making the coil. It will not be installed anywhere. Further intent is that the coil should not make any direct contact with the stovepipe, and that there will be an aluminum shield surrounding the outside.
Although I mention heating the domestic water, the primary goal is to transfer heat from the stove location to the radiator that will one day be placed at the coldest end of the house. The system design calls for continous circulation through that radiator with a tap off of it somehwere to feed the existing water heater.
