heating shop

I've got a chance to get a gas furnace cheap for my shop, but my question is should I put in directly in shop and let heat blow straight off furnace or should I put it in side room and duct it in to shop? Was wondering about how noisy furnace will be.

Have min right in shop. Not that noisy. Fan can be left on slow, Will depend on SIZE of shop area too.

I would mount the furnace as high off the ground as possible. Heat goes up, so by putting the furnace up high, it will grab the warm air and blow it to the floor.

I have a garage with 16 ft ceilings. I installed furnace as close to ceiling as possible.

Mounting a furnace up high also keeps it above combustible fumes that might be lurking near the floor.

I put my furnace in the firewood room lean too behind the pole barn, then ran ductwork to the front of the pole barn.. Insulated all the ducts and it works great when I need fast heat.. I don't usually heat the barn due to my plow truck sitting in there.. I just heat the "john" with an electric heater to keep the seat warm.....

I have 9' ceilings and it's a standard house furnace. The shop is only 15x35 with a small room off it that's 8x12

Not exactly sure what a standard furnace is. If the warm air comes out the bottom of furnace then hang furnace form ceiling. If the warm air comes out the top, mount furnace on floor, make a cold air return air duct to suck air off ceiling.

George,

I beg to differ, always have the air intake
to the furnace on the floor. Let the blower run
continuous to move the cold air off the floor so
you don't freeze while you are on the creeper.

I installed a two way wall switch onto the furnace fan. When I'm in the shop the fan's on low and pretty quiet. When I'm not in the shop the fan's on high and pretty loud.

When you have 16 ft ceilings, it can be 90 degrees on the ceiling and snow on the floor. Heat goes up, so grab it and push it to the floor. My 16 ft garage was used as a body shop, sanding dust in the air. You could see, ceiling fans couldn't push the heat down. Heat would get about 1/2 way and then rise.

MY BIL, who has a HVAC business, built a house with very high ceiling. He installed two large air returns as high as possible at each end of the large room to grab the warm air and send it back to furnace/AC.

I find it better to put the heat back on the floor vs removing it from the floor.
