I have forced hot air as my central heat & a coal stove in my basement family room. The coal stove really warms the whole house (a split entry ranch) except on the coldest mornings. (the regular heat really comes on very rarely)
In order to spread the heat (from the coal stove) more effectively through out the house, I did the following:
1. Disconnected a round 6" supply duct from an upstairs bedroom. (this duct runs above the coal stove & was unused as it is the 2nd duct in the bedroom above which I like to keep cool anyway)
2. Cut this duct just above the coal stove & connected a 6" duct fan into the (now open) pipe so that the fan would blow the warm (coal stove) air back into the main supply duct. (the reverse direction of the central heat)
3. Added a 90 degree elbow & made a small hood above the suspended ceiling over the stove.

I figured this would help distribute the air through the main duct when the normal heat (which rarely comes on anyway) isn't on.

After I did this I had a few thoughts:

Are there baffles in the main duct that would block air coming from the reverse direction & thus hinder the flow?

The round 6" branch ducts are attached at the top of the main (square) duct & thus I figured the warm air would natuarly find it's way up into these ducts anyway??

Any thoughts or tips on how to increase efficiency would be appreciated!

If you could get the heat into the cold air return you could put the fan on it's summer setting and pump the heat around the house. Maybe this isn't feasible.
