Ducting a stove to the upstairs

Ducting a stove to the upstairs

PostBy: TD On: Tue Oct 10, 2006 9:30 pm

I have an alaska channing III in the basement and I would like to duct it to blow some warm air to the first floor. So I have a couple of questions. Does anyone have a picture of what the optional top looks like for the alaska stove and do I need any type of filter in the duct work? Thanks in advance, Tony. I'm looking forward to the heating season this year. Also did I mention that I love this site!

I just bought a new channing with the top you are talking about,sorry I cant put a picture on here yet, but it is a full size top with a cut out to go over the exhaust pipe and then a 6" take off in front of that.
The take off is in the center of the top. It still has an opening that will blow air out the front but I am going to tape mine off so all the air goes up through the take off. In a day or so I am going to duct mine into my cold air return on my forced air furnace and use a spring loaded damper upstream to keep heat from coming up the cold air return.

the fan motor on my stove will keep the heated air moving into my duct work, it will have to pass through my furnace filter.My thermostat can be set to cycle the forced air system when I need it.

It will take a little trial and error, but should be worth while. I am heating an older story and a half about 1500 Sq Ft. The coal stove is in the basement. Used pellets and corn last year and cut my gas bill by 60%,so this should do much better.

I will try to borrow a digital camera and get you a picture,I am technically challenged. ( Guns,Horses,Airplanes and stoves I do OK...Computers, I struggle with!)

i tied my hot air blower from my Harman mag into my central heating duct and it does fine, I could use a larger circulating fan but havent gotten around to doing it yet after five years.

what I did to stop the flow of air from coming out of the front of the stove was to take a piece of 1" ceramic rope (braided) and jammed it into the opening so that all the hot air is forced into the duct

years ago where I used to rent I had a franco belge and wired a 5" pipe up to a floor register in the living room and foiled off the top surface so all the hot that was channeled up the pipe and into the room above. it worked well and cut the electric bill by 3/4.

it was also nice bing able to look down through the register to see what the stove was doing.

I have an older model Alaska Stoker, I cut a six inch hole into the top of the stove and made a collar with a flange on it and attached it to top of the stove. I used six inch stove pipe from there and then ran flex duct into my existing duct work from my gas hot air furnace. I ran it into the supply side. The fans on the stove are not actually large enough to blow the heat out of the registers, but you can feel the heat trickle out. It makes a huge difference. I was also thinking of running mine into my return duct and setting the blower on the hot air furnace to run constant at a slow speed to circulate the heat throughout the house. The only thing is when I change the settings inside the hot air furnace to have the fan run constant on a slow setting, the fan speed doesn't seem to change. I don't want to listen to that furnace blowing all the time. Is there anyway to hook that to a thermostat for the blower only without firing the gas furnace. (I don't know how to post pictures either). Thanks.

I am working on the same concept with my Keystoker, cut an 8" hole in the top and ducting it into my existing furnance in our new house. I may use a separate inline booster fan with a thermostat.

Depending on your thermostat hookup (# of wires) would determine if you can control you motor separately, you may be able to hook a separate thermostat up just for the blower.

You furnance motor may have a circuit board to hook up the blower to a separate switch or relay via a thermostat.

Here is a stand alone plug in thermostat that I am using.

Here's my stove ready to go, its 6" pipe with a 4" reducer into flex duct. It sounds like about the same setup that Ed has. I have about a 15' run to the vent so I thought a smaller duct would move more air. I turned the fan on low and can feel air at the register. A friend at work made the top for me, it has a 6" coller welded on it and it is a perfect fit, I think I owe him some beer. I plan to start it up tomorrow and will post the results. Thanks for all the input.

Yep, that's pretty close to my setup, not much difference at all. I have a different style alaska stove. On the I.D. plate on the back the model isn't stamped, so i'm not sure which one it is. How do you post a pick? Do you go below and put the file name in the attachment box and upload it?

just curious are you running the duct far away to other side of house or into duct from your furnace. Are you ducting to just one register? Are you putting a booster fan on it?

To post pictures, I click on browse, then find my file where pic's are located and click which one I want ( you have to repeat these steps for each picture ) then click upload then preview to make sure it worked then submit. And for the duct, it's the only one. I hope by keeping the basement door open it acts as a cold air return. I just fired the stove up and on the lowest fan setting I have heat blowing lightly out of the vent. :) If it's not enough I"ll add some kind of inline blower.

Looks like your friend made you a hood that won't allow any air out of the front, and forces it all in the duct work. I bet you'll really get some heat out of it.

I'm getting good heat from the single register, but I think I need another one on the other side of the house. I plan to add a T and another register and maybe two inline blowers, one in each direction. That I think will even the temp. out upstairs. The new top on the stove works real good, no air leaks out, and there's more than enough heat in the basement without a blower on down there.
