Wood boilers are very expensive and I'm not sure I want to invest in a system that will just get used during the coldest times of the season. Our house is going to have radiant heat in the slab. And AC ducting for Summer.
Here is what I'm thinking; Get a common used wood furness made for hooking up to the air duct system. Remove sheet cover and wrap with 1" copper tubing. Replace sheet cover. Plumb to storage tank. Keep the duct work attached. Then by thermal siphon and or pump, circulate to the storage tank. Radiant heat system would pull from storage tank as a pre-heat. Keeping the duct system intack would allow to have the squirel cage "cool" things off if it reach excessive temps. Other wise, all heat transfer would be the copper pipe.
The storage has a duel purpose, I'd like to have hot water solar panels feeding this tank as well. So in theory, sunny days the solar would pre-heat and during cold cloudy days I'd have a fire.
