Hey guys,

I've read a ton of posts on here and garnered a lot of information, which is understandably sometimes conflicting as there is often more than one solution to a problem.

I have a 40x60 steel shop, 16ft walls, spray foam insulated. When I was building it, I made what I now believe to be the mistake of doing unit heaters instead of radiant. We are in Alaska, so we use heat with some frequency.... every now and then, if you will.

We also own a dog kennel. Our first attempt to remedy our heat problem was at the advice of someone at a local HVAC place that didn't work at all. We did ducting that is 10 inches with 12 sources and one 700cfm fan. You can probably guess how well that worked out.

We just moved one of the unit heaters, as you will see in the picture, it was between the door and the first wall, so it was useless. Now we have more than enough heat on the mezzanine level - where the offices are - but it gets super hot and stays super cold downstairs.

I'm wondering if there is any sort of ducting solution here. I'd rather not do a fan as being able to use filter boxes on the air would be ideal. I already have some pretty expensive filter boxes and I'd like to use them to filter out some of the dog dust, etc.

I'm only showing the second floor as the first floor is pretty much wide open.

Conveniently, I happen to have a genie lift I'm storing for someone here and if there's a solution I could do while it's here, that'd be great. I appreciate any help you can offer!

Use ceiling fans. Your goal of killing 2 birds with one stone won't work without a lot of investment in ducting, fans, etc.

You can still install some filter boxes if you want, their purpose will be to filter the air while the ceiling fans circulate the air/heat.

You need to move that hot air down. You could have ducts do it. **** in the air up high and blow it out on the lower level. Put a filter inside of them. Maybe have a 1'x2' trunk going up the wall with a fan in it to **** air from above and blow it out below.
Otherwise a cheaper option is the ceiling fan way. Get big, decent fans. Not the cheap ones off the shelf at HD.

I'm unsure of your budget, but we have specified air rotation units at some of our facilities (vehicle maintenance, warehouse, etc) that are meant to do what you are looking for in terms of cycling air, but are usually ignificant in size and cost. They can feed in fresh air, heat cool etc. Example here:

If you have all of the heating and cooling portion taken care of, you could design a similar vertical rotation unit with fans and a filter. I was considering this eventually for my 48'x48' x 19'(peak).

I heat with wood. Theres next to no air movement with a wood stove and thats basicly what your seeing in your shop. You need to move COLD air to HOT. Dont try and move hot to cold, you will cool the air. Try aiming a barrel fan on the ground streight up.

Im not seeing any pics.
