How many Ceiling fans are in your shop?

Wondering how many ceiling fans would be for sufficient air circulation in a 32x48x12 with cathedral ceiling. My barn is in Northern MI so winters are cold and want to keep the hot air as low as possible. I ran wire in ceiling for one fan in the center of the barn. Im having second thoughts on if I should run 2 fans or. Not.

If you have decent insulation and a fairly open space, it doesn't take all that much fan to keep the air moving and well distributed. If you're not well insulated, you'll get a lot of stratification and need more fan to move the warm air down.

2- 60 inch fans in a 30 x 40 ft. space and does the job well. Keeps the air temp. even for central HVAC without ductwork running everywhere.

I've been monkeying with the final lighting layout. I have 4 of them in 1000 sf space, but a prime goal is to keep cool in the summer, dry out the boat between uses, etc. I will only run 1 of them year round to stir air.

I put all of mine about 6" down from the ceiling. I think you'll get greater air circulation if it can be hung on an 18-24" downrod.

Were I you, I'd wire for 2 or 3 of them. Can always put the fans in later as funds become available.

I have one in each of my other existing shop bays, smaller and not reversible, can get a bit chilly at times :)

I've got two 60" Agrifans in my 32x40x16. I have a variable speed controller and run them towards low in the winter and high in the summer. They do a good job.

I planned for two fans in a 30 x 38 in a three bay garage but ended up with two lifts. Could only put one 7 ft fan in the center bay. Works fine for summer and winter. Keeping a fan down from the ceiling works much better.

I have none but I do have a simple 20" box fan running 24/7/365. Running on low, it'll move air nice & slow as a cheap alternative.

1600ft2 x 12' with one 17' high bay. The single fan is a 72" MinkaAire. I keep it on speed 1 or 2 (of 6) to keep the air gently moving, since the 3 tons of minisplits are in one corner.

I also use floor fans to dry off vehicles if they come in wet.

36x56, 12' ceilings and I have (2) 72" fans and (1) 54" fan. They were just installed last month and it's been cold so I'm unable to report on how well they work.

You guys that have two fans. Do you run them opposite direction in the winter or both always down summer and winter?

Thanks

I was wondering that as well, do you just set a ladder and flip the switch to change direction or just let them run one direction year round?

I've been thinking about adding ceiling fans. The heat is okay in the summer. As for winter, I'm well insulated and only have in floor radiant heat in my washroom and the first foot of the shop only because there is a living space on the other side of the wall. I'm going to go check the upper wall vs lower wall temps. Damn, I might have a project for today.

I have yet to install mine in my shop.

But in the 26 x 30 attached garage, now for the DDs, I have one powered by the opener outlet.
It hangs 12 inches down from the ceiling.
It is blowing up, for max across the ceiling and down the walls air flow, 24/365.


I plan for the same in the shop.

None.

Can someone explain to me the significance of "moving air'?

Reading a lot of these comments I'm feeling peer pressure to get some kind of fan in there. :bounce:

Sometimes the shop gets overloaded with air in one place and if I'm trying to do a project in that area it gets in my way. The fans help me to move the air to another part of the shop allowing me space to work.

In my new shop zero.

Old Shop 2 48 inchers. Running on low 24/7/365 since Dec 17, 1999and still going. The ceiling in that build is 23 feet to the deck and 20 feet clear.

Might have a couple installed some day when I have the Electrician back out for a new machine hook up.

Regarding changing fan rotation direction for up or down air flow, I leave my 7 ft single fan blowing down all year long. Run it at slow speed in the winter to move the surprising amount of hot air from 13 ft ceilings down to the floor level without creating a draft. In summer, I turn it on high to get a cooling effect until it gets really hot. Then I turn on the AC. Mine and many larger fans have a remote hand held wireless controller you mount on the wall that allows you to change the direction without climbing up to flip a switch in the fan or pulling on a hanging cord.

I just checked temps with infrared temp gun, 50 deg on the wall beside me, 52 degrees 14 ft up at the peak. I’m sure I can tell the difference between 68 and 70, not sure about 50 and 52, too cold.

My shop has 12' 6" ceilings and is 30' by 60' and I have two fans that stay on 24/7/365. I don't change rotation, they push air down all the time, I do vary speed so it doesn't feel like a breeze on me in the winter.

I have 1 60" VES industrial fan in my 32x32x12 shop. I installed it with a VES wall controller to adjust the speed and reverse the direction. I moves a ton of air and keeps the heat down where I am instead of up where no one is

When I was building a 12 foot wall building, I noticed a lot warmer temps standing on a 6ft scaffold than what was down at the floor. Adding a fan (winter **** up, summer blow down) made a big difference in over all heat and cooling.

I run 2, I reverse them in the winter(switch is under cover on fan), with 14' ceilings it helps circulate the heat off the ceiling.

I really didn’t find any benefit to reversing them, frankly, in my shop I think it made things worse. Besides you have to get up on a ladder and switch them and I am afraid of heights.

This thread had me curious. I have in-floor radiant in my shop and keep the stat at 50 deg. When I'm working in the woodworking side of my shop (40'x50'x14'), I supplement the floor system with an outdoor Bryan wood forced air stove. Within an hour of starting the fire in the stove, the temperature goes to 65 deg, and my stat is app. 5 ft. high. Besides the stat, I have 2 indoor-outdoor thermometers in the building, one in the wood shop and one in the vehicle bay. When the temperature in the shop got to 65 yesterday, I mounted the second thermometer up on the ceiling. After app. 30 minutes, it read the same reading as the other thermometer and the stat, and they mirrored each other throughout the day. I had thought about putting in a few fans to move the hot air down, but after my experiment, I think I'll pass. My only guess for the temp's being the same is that the wood furnace air intake-cold air return (inside the shop, similar to a household furnace) is up high near the ceiling, and the hot air comes out low.

2 Home Depot units in my 24x24 with 10’ ceilings.

Switch up summer and winter. Only thing I need to do is install a switch for when I am welding out there. ***** when fans are tied into the stereo circuit.....
