Moving heat to other rooms

[touchthewindrider]

Just wanted to know if anyone uses, or has used, a doorway fan? Those corner fans that
fit an upper corner of your doorway? I'm trying to move heated air from one room to another.
What has worked for you?

Thanks,

Try and move the cold air. Cold air is easier to move because of density. Small fans placed so that you blow cold air into the heated room. Natural convection should pull the warm air back in at ceiling height.

This.

Results are almost immediate.

Not quite as fancy as those small door fans . . . or as exotic as those small fans you place on the stove top that work without electricity . . . but this method works . . . and works well . . . to distribute heat throughout most of my home.

So, small fans placed on the floor in open doorways, blowing air OUT of the room, should result in the effect desired...natural convection?

I'm trying to get my dad to try the "move cold air" method this year at his house. They used those corner fan blowing into the back rooms and it didn't work, so they just keep a floor heater in their bedroom now.

Yes . . . sounds crazy . . . until you try it and discover that it works. Sets up an air "current" with cool air being pushed by the fans towards the hot stove, hot air near the stove then is "pushed" out to the adjoining rooms . . . setting up a loop of sorts. Only two areas in the house that are notably cooler is my attached mudroom/boiler room/bathroom and the master bedroom/bath which misses quite a bit of the heat as the heated air curls around and goes up the stairs to the second floor, by passing the master bedroom . . . it's all good though . . . I like it cool there and we have an electric blanket when it gets really chilly.

Thanks for the ideas. I will definitely give the fan blowing cool air out of the bedrooms a try.
