I recently purchased a pellet stove for my 24x24' attached garage which is now my electrical shop.

The door from the garage enters into my kitchen, I have a 1,200 sq' 1 story L shaped ranch house with forced hot air heat. At the far end of the house is the living room, an office and the master bedroom.

I'm trying to move air from the garage to the furthest rooms of the house not to do all the heating but to suppliment my oil furnace. Leaving the door open helps to heat the house but not as well as I would like.

My Idea is to cut floor registers into the 3 furthest rooms and run a duct through the basement to the garage and use some kind of low noise power blower off a thermostat to push the air into the garage inturn pulling warm air through the house to the furthest rooms. I don't want to cause a wind tunnel from the garage through the kitchen just a slow movement of air that would also help to pull heat from the kitchen into the other rooms.

My Questions are

1: Does this sound like an Idea that would work?

2: What amount of CFM should I shoot for?

3:What kind of power equipment is available to move the air?
(variable speed would be nice)

4: What type & size ducting would be best and what size registers?

5: Any other thoughts on how to accomplish this project would be greatly appreciated?

Thanks Stan.

You might want to check your local building codes first it might not allow what you want to do

I no longer use it for a garage, I know there is suppose to be a fire separation between the garage and living area. It's filled up with equipment, shelving and material stock. I live in Vt so there is no state code for single family homes and also the town I live in has no code standered, If I was parking vehicles I would not think of doing it. I guess I'm the AHJ so I reclassifed it as an electrical shop.;)

I would look at your existing furnace and go with similar or slightly smaller components. Many of you furnace blowers come with multiple winding so on start up the technician can select the speed to give the proper heat rise for the best efficiency and least noise. Bigger ducts and a lower fan speed are quieter.
