How-To "Push" Heat From Basement to First Floor?

dewey · Post by **dewey** » Sat. Jan. 05, 2008 7:06 pm

Our basement rec room (home to a new LL coal stove) is 15-20 degrees warmer than our main living floor. We have a hole in the floor between the rec room and the living room that would be an ideal place for a fan to push heat up. Does anyone know of a floor vent that has a fan in it? Thanks.

You may need a return air vent. Check out this thread

This will probably start a controversy.

I've got about the same situation. I've got two vents between levels, with dual fans, which can blow or suck through the vents.

Originally, I was trying to blow the heat from the lower stove room, up to the living room. It didn't seem to work the best. One day, while dust mopping in the area of the first floor vents, a dust bunny floated upward, but just kind of hovered, not too far, above the vent.

I decided, even though I had a return to the basement floor on the other end of the house, the cold air was right at the first floor vents and would have preferred to go down them. So, I reversed the fans to blow the cold air to the basement and put a Vernado fan at the top of the stairs, on the first floor, to send the warm air, coming up the stairs, to the rest of the house. While it isn't what I had hoped for, it's the best I've come up with so far. It does, "try" to keep the temperature down in the stove room.

Bottom line: It easiest to move cold air (I think), and let it displace the warm air to where you want it.

Yes, I have seen a smaller "register" type floor vent that had a small fan in it for just this purpose. Unfortunately I don't have a link to it tough.

I have been working on the same problem right now I have my Keystoker 90 hooked up to the blower on my oil furnace with relays to turn on and off the blower. It blows out of ducts at 93* in all rooms. I don't know which would work better a higher cfm at lower temp blowing out in all rooms or the stock blower blowing at higher temps blowing out 1 register in the center of house. I haven't tested the single register stock blower configuration yet.

I just finished installing a flexible insulated ducting from the stove (garage) to a register in the hallway by the bedroom doors (up one level).
I leave the door to the garage (at the bottom of the stairs) open and it acts as a 2-way travel for air. The duct I added to the stove captures the distribution fan air and traps it into the duct. Right now the stove is idling and the house is 75 (well, it did get to 47 outside today...)

The flexible duct is not pretty, but it's sure warmer then letting the air flow across the garage and upstairs. I had to keep the garage 76-78 to keep it 68-70 at the top of the stairs. Now its about 72 / 70. Much better.

Thank you, one and all. The Airflow Breeze Vent Booster is exactly what I had in mind. Now, I just have to find one.
