Anyone know anything about HVAC and home heating?

I have a forced-air oil furnace and a plain-ol' wood stove in my house. I would like to rig up a fan that would force air from the room where my wood stove is into the same ducts that the furnace uses to push hot air into the other rooms of the house.

Is it really just as simple as putting in a fan in the appropriate place? Do I have to worry about back pressure from the fan pushing air into the furnace when it's not running?

Does anyone know what I'm talking about?? If not, I'll make an illustration and post that.

Thanks for any input I can receive.

but it had a fan built in.
If your stove is a double wall type, I can't imagine you would have a problem with back pressure.
Our stove worked so well that we would have the doors open when it's 4 degrees outside. Kept our 4 bedroom house toasty.

The duct work to individual areas gets increasingly smaller as it spreads from the source (your furnace). Thus forcing air into the small end will necessitate weighted dampers (flaps) at numerous points. This in turn adds resistance to the air flow, the blower motors of an HVAC system are powerful and consume more energy than most realize - it could be a project that takes a long time to figure out, and the ROI (return on investment) may be small.
