Hanging furnace airflow direction?

[srt20]

We built a 30x45 garage. I bought a Beacon Morris 75k BTU natural gas furnace to heat it with. Everything is insulated. 18x8 and 9x8 overhead doors along the 45' side.

My question is, what direction do I aim the furnace. It will be mounted in a corner in the back. Do I aim for the opposite corner, or along the back wall?

Most everything I've seen in the past has been to the opposite corner. But my brother had a hanging furnace put up in his garage by a HVAC contractor, and they have it flowing along the back wall. His reasoning was the airflow will circulate around the garage. Granted his garage is a lot smaller, a biggish 2 car.

What do you guys think? Thanks!

I aimed mine across the back wall, about 6' from the back, aimed to blow across the area I use for most of my projects.

Point it toward the centre of the 45' wall with doors. That way it will bounce from there to the 30' wall then to the back wall and back into the air flow. This will make the airflow circulate around the garage.

I'd do opposite corner. Or better yet, mount it so you can rotate it 90 degrees and aim wherever you're working.

Well, 3 different answers, lol.

Any more help is appreciated.

Most heaters that I installed would blow towards the doors to try to heat the cold air when doors are in use. If you have 12' walls, ceiling fans REALLY help. All you need are the cheap ones or one from a garage sale.

I have a 24 X 36 garage and my Hot Dawg natural gas heater is mounted toward the ceiling in one corner. I have the fins pointed downward and outward and the warm air is blowing towards the opposite corner. It seems to work out very well that way, at least in my case it does. The whole garage gets warmed up in a fairly short amount of time. No matter where I am in the garage there doesn't seem to be any cold spots.

I did the same as the previous homeowners had theirs setup before they took it with them. And same as Family Handyman shows here.

Hi

I put in a cold air return 1 foot off the floor and up the wall, then had duck work made that was round to go from the wall to the fan that was big enough to almost enclose the fan. This worked very good to get the cold air off the floor and has been working good for 7 years.

You want an air flow like this. Place your thermostat near the heater.
