Insulate and heat our garage

[wiegs1]

In an effort to keep our garage comfy from the cold Wisconsin winters we are going to blow in r49 in the attic of our garage and purchase a 50,000 btu heater.

I have attached a drawing of our garage layout. I think I found the place play to put the heater to keep it close for venting. I am going to vent through the roof but need to pipe it about 8-10ft in order to have the proper clearance on the roof for code. I tried to draw out my plan. I will go strait through the attic from the unit and elbow over with a run of 8-10ft, then pipe it up through the roof. This will keep it 10ft from the second floor walls.

Do these seem reasonable? Where is the best place to purchase vent pipe? Seems like this stuff is expensive.

I would think using 45's vs. 90's would be better. I'd also using a fan or two to move the heat around and get it all off the ceiling.

I have 12' ceilings and use 2 box fans to push heated air to the far end of garage and down.

Why not purchase a hanging unit that vents through the wall? I would recommend it also has an intake that draws combustion air from outside. Ceiling fan(s) will help also.

I am going to purchase the mr heater 50k btu hanging unit. I am just not a fan of the wall vent. I have an overhang and the pipe would stick out a look silly.

I have a 60,000 used mobile home furnace in my 20'X20' garage

Not all units use a “stove pipe” for exhaust. In my previous garage I had a hanging unit that has a small exhaust/ intake that mounted just below the roof line, it did not protrude from the wall more than six inches. The heater has a draft indusser fan that pushed the exhaust, no need for a pipe to create exhaust draft.
I now heat with hydronic and would never go back to a conventional type heating system.

Menards has pretty good inventory on "B" vent which I suspect you'll use.

I too had a hanging furnace that I added a power vent to. Nice looking vent out the side. Hate holes in the roof.

Vertical bvent kits are cheap

Mine was under $70 shipped

I just had a similar setup installed. Exhaust vents out the back side of the garage wall so I don't see it from the house or patio. Its practically flush mounted.

Would that not have poor efficiency trying to heat freezing air?

It will be cold over by the big door across from the heater. Fans will help.

Garages leak like crazy, especially around the overhead doors. Almost impossible to seal them well. Out combustion air is really not necessary.

Was just looking at b-vent pipe at menards. Seemed reasonably priced. The Mr. heater also had a vertical heat vent “kit”.

As far as the code goes of where to vent the pipe, what is the code? How far away from a vertical wall for the second story does it need to be? I’m looking to install a similar set up. I don’t want to see the pipe from the front of the house and is prefer not see it from the window in our shower

Menards has lots of Pamphlets on how to install B vent. My big Maxx required Stainless Steel pipe. I went vertical do to reluctance to put a hole in the roof. It vents out the back so no one sees it. They do recommend mounting 2 feet out so the exhaust doesn't go up your attic/roof vents.
