I am contemplating the following design:
A house has a primary electric heat pump heating setup consisting of an outside heat pump, inside air blower and all the duct work that distributes warm air through the house.
Now I want to also be able to burn wood to heat my house. Would it be possible to leverage out the existing duct works from the primary heating setup described above and conduct air into it that's been heated by the wood stove in the basement of the house? I think I have seen people do it but with radiators using water and air is a different medium so I imagine it'd be different. Would the stove be heating air directly or heating coiled coolant, similar to the heat pump if I understand how it works correctly?
Essentially, every time the person living in the house felt like doing some physical exercise to chop some firewood, they could help their electric bill by generating BTUs by burning wood, which may be cheaper than electric in the area.
