Heating Duct Question

[Finley]

here goes...

i have a plit level home, and an attached one car garage. my garage wall is dividing the laundry room from the garage, and inside the laundry room, the ducting is plainly visible, but when it routes to the garage, the ceiling drywall drop down to accomodate the ducting. what i want to know is, can i simply cut a template for a heater vent in the drywall, cut a hole in the ducting, and put a piece of down-duct onto the main ducting, then attach the vent piece...i really want a heated garage, but dont want to tear up a whole piece of drywall to do it

Don't know the answer to your question but if you put in a supply you will want a return also.

I'm not sure its allowed by code to run the heat into the garage. Don't think you'll want the fumes from the garage getting into your house.

Code doesn't allow that for the reason stated above - you will **** fumes from the garage into the house.

damn...how do you go about heating a garage then? other than the crappy "portable furnace"

You could install a seperate permanent unit in the garage area. Hanging forced air unit such as the Hotdawg or Mr. Heater vented units. They come gas or propane fired and can side or vertical vent.

You can run supplies to a garage but not returns. The supplies just need to be 18in or more off the floor which they would be. Fumes would not be an issue any more than they already are in a split level where the garage is under the house like yours seems to be. The only thing I can tell you is it will take away from those rooms that the trunk line feeds, however heat rises so it would be really "lost" but the rooms above would be uncomfortable if you take too much away. Unless you only open the heat to the garage when working in it.

thanks for the input...i would be running a supply, and no return...ad i spend a fair amount of time in the garage, and being that the garage is on the lower level, i imagine that heating the garage would do more good for the heat in the rooms above it, as opposed to leaving it cold?

Right. So even if you invest in a separate unit you still wont loose. Also if you add or already have central air you can have it in the garage also. just make sure to seal the garage up with weather stripping and insulate the doors.

CC upon further review that's how my garage is heated. It's an attached garage under the house. It has a supply but no return. I've been in this house forty years, never had a problem. Good thing I never put a return in. Thanks for that tidbit of info.
