Warm air transfer
 
Hi all. I would like to know if it there is a kit or, if it's even available, to transfer warm air via a ducted fan system from one room where we have a wood burning stove to the back of our house, actually just a bedroom.
Because of the high cost of natural gas, we've been keeping the furnace off, but our master bedroom, which is in the back of the house is very cold. (been in the low 30's outside)
The distance would be about 75 ft or so of duct. Just raising the temp 10 degrees would make it worthwhile, especially since the heat is "free". (I scrounge firewood)
Ideas??

That is quite a long way to transfer heat and gain much out of it. My first thought would be to run a well insulated duct betweenn the rooms with a duct booster fan in the duct. But, I'm not sure how much heat loss there would be in that distance. A furnace plenum runs around 125 degrees and you are losing alot by the time you get to your registers with that. I do not know of a kit specifically for that however. Many woodburners have duct outlets as part of the stove. I assume yours is not that style.

Try running the furnace fan by itself and send some of that heat to all the rooms. The air may feel cool and drafty but you are 98deg i fit sends in air warmer than the room is it is heat. It is a easy try and if you dont like it turn it off and your back to sq 1.

Ayuh,..

John's Idea would work Great if the furnace's cold air return comes from Near the woodstove.....

Thanks for the ideas. The main prob is that the return is in a different room. Usually it takes several hours to heat the room with the return, but it may help to run the fan just to get some circulation.

My house has a return in each room, including one where the wood burning insert is.

I do notice an increase in temperature in the other rooms when I run just the FAN only. However, to minimize cost and wear on the AH fan, I just put an oscilating fan in the doorway of the room with the woodburner and aim the air to the other area of the house...makes a big difference for me.

Can you add a new return near the stove?

The blower in an air handler is a continuous duty blower.
Running it 24/7 to circulate heat from a room with a stove into the rest of the house doesn't hurt them.

Add a return to the room with the wood stove, it will pay for itself.
