Warming a Cold Room

The advice on hearth.com was bulletproof. I hooked up a fan in a cold room and blew it towards the stove room. Cold room warmed up in a matter of minutes where heat never flowed adequately before. The fan rests on the floor and is about 12 inches in diameter. It's moving the coldest most dense air down there, and worked very well. I had experimented with fans before but tried to blow warm air towards the cold room and had zero success that way.

I'm sure you meant fan. ..or you have a real small stove!

Good to hear it's working for ya!

Good catch...Fan. And yes, it's a nice trick!

Simple fixes are the best

This sounds like a nice approach. Does this work at any lower temp, or just "cold"?

Glad it worked out.

It works for moving the warmer air simply because cool air is more dense than warm air. In the case of the house it is not extreme but is enough so that it works ideal.

Yeah...I second that. I am going to experiment with a box fan next. I have a circular fan that rotates towards the floor or the ceiling. I was experimenting with rotation on that, and it's not really necessary. Just place it a few feet from the door in the cold room blowing towards the open doorway. In about 15 minutes, temperature should be noticeably different. I think any temperature difference will work but a larger spread will be obvious fairly quickly. Also helps cool my overheated stove room. I don't like having 80 in one room and 65 in another adjoining room. Seems like a waste.

how would i do this for heating the bedrooms? fan in bedroom and blow the fan?

In use a tower fan - works great. Put it on the lowest setting - Fan approx. 36 inches tall

A simple and small desktop fan sitting in the doorway or close to the doorway blowing out should do the trick. Running the fan on low speed should not be noisy either. When we use the fan to move warm air to the back of the house we use a small vornado fan. I think it is 6" diameter but would have to measure to be sure so let's just say it is really small and we run it on low speed.

moving some cold air out will bring the heat in to replace it. the more air moved, the quicker it will heat up

One blowing down and one blowing up? I have a stove in my basement that overheats that space while the upstairs remains cool. Any suggestions?

I have a similar setup. Fan on the lowest setting is whisper-quiet and house is toasty top to bottom.
