I have a Bixby 110 in my Family Room. The room is 20x28 and it will heat this room on the lowest setting to 90 degrees. I have a floor oscellating fan sitting in the 4'x7' cased door opening that leads into my Kitchen but I can not draw enough heat out of this room to suppliment heat in the other rooms of the house, plus I dont like walking around this fan all the time. I was thinking about cutting some room to room fans into my walls(www.iaqsource.com/product.php?p=broan-nu...785&category=885). I want somthing that will not look to out of place, not noise, and that does not let to much sound tranfer from room to room. Has any done this? Is this a good idea or am I going to regret it? Would it be better to put them by the ceiling to pull the hot air or by the floor? I would love to pull the hot air from the ceiling in one room and then pump it out at the floor in the other but not sure how I would do that.

I have Entreeair fans installed in the corner of my doorways which were installed when using wood as my primary heating source. They made a huge difference in helping to equalize the temperature of the house. They are only 100 CFM but quite noisy, about 50 dB according to the manufacturer. At night when the house is quiet, 50 dB is quite loud.

IMO you are better off moving the hot air at the ceiling level rather than the floor, you'll move the hottest air around the house and prevent stratification by creating forced convection in the room.

Pulling the air from the ceiling and discharging it at the floor would involve some sort of duct to make the vertical transition. You would be adding some measurable amount of static friction which that type of fan isn't necessarily designed for which I think would cut down on the CFM quite a bit, if not over amp the motor.

Move the cold air to the warm room you will have much better luck. I used small 12 inch box fans in the doorways.

On the forum are a series of discussions on moving air, and one of the options is using a LUX 1500 thermostat. It differs in that you can run the house furnace fan on what it calls the "clean mode". this is a cycling of the entire homes air by the use of the furnace fan. Runs as often as you wish by adjusting the cycle at the thermostat. I have one and have had it in use for going on the third season and would be without it.
The LUX 1500 can be bought on line(make sure it has the clean mode fan setting option), shop the price varies.
Easy to install do it your self project and straight forward instructions for programming.
Hope this helps
regards

Cooler air enters hot room at fan/floor level and is replaced by warm air above. I use a big box fan in the doorway of my furnace room and the ambient heat from the corn furnace heats the rest of the basement and up the stairs to the back porch, which otherwise would have no heat.

dallas, I have my stove in a family room with a 14' ceiling I went into the attic and cut in 16"x16" holes near the ceiling then used duct board and boxed in the wall cavity from the holes to just above the other ceiling joist. Then put a starter boot in the duct board used flex duct and a duct fan that can be bought at Menards, ran power to it from a switch down in the hall then piped it to the other room and dropped it in the ceiling with another boot used standard covers available at any hardware store to cover the holes, even painted the ones in family room. It pulls heat off the ceiling in stove room and helps move the air. I know all houses are not the same this may not work for everyone. The simplest way to help move air is with a fan, if you can set a fan blowing cold air into the stove room that really helps move the warm air, I like the Vornado fans but any would work. Sometimes there isn't room for fans or in my case wife didn't like them so had to get creative, Good luck

I looked long and hard for a wall fan that moved a decent amount of air, but had little luck finding anything, not to mention they are quite pricey on a $/cfm basis. I ended up going the cheap route and bought a $20 window fan (actually two, so I had a spare as backup). It moves considerably more air than most dedicated wall fans, has two speed settings and a thermostat. Best of all, it's into it's 6th heating season and the spare is still sitting in the box!

I just purchased this fan....seems like a great idea to get the heat moving around in the house, hopefully it works.
