Finish Room Heating12/27
I have a 12 x 26 finishing room with 14ft ceilings up until it hits the front of the booth which is 8ft high. It's an open face booth that I built a room around.
I have done a lot of hunting around the web and on this forum to search for a safe means to heat only the booth separately from the rest of the shop.
I have forced air in the shop which I keep at 55 degrees.
I would like to keep the finishing room and all of my finishes at 65 at the very least when it's not actually in use.
During finishing, I set the forced heat to 70 and start moving fast. It actually works okay and I can feel a steady breeze of warm air on my back while I'm spraying. It's the only time it's actually comfortable to work in here in the winter and I can drop down to a t-shirt.
I looked into the propane radiant heat tubes, but the issue with not storing anything directly under the tubes isn't ideal for me. And I worry about blowing myself and the building up. Again, the rest of my booth area serves as a clean drying room for freshly finished parts. I need all the space I can get in there for racking parts.
Hydronic radiant heat is out of the question. If I owned this building, sure. But I don't and I am not dumping more money into infrastructure I can't take with me.
I'm looking for some sort of reasonable fix that isn't permanent to the building. First and foremost it has to be safe due to the fact that I only work with solvent based finishes.
I keep the finish room doors closed when I am not using it to keep the dust from the rest of the shop out. That also keeps the fumes in. So I am not about to just throw anything in their to heat the space in the off hours.
I came across a heater by a company called Fillon Technologies. It's listed as an explosion proof heater. Has anyone seen these or similar? Or used them for that matter?
I have a similar sized finish room set up , except that my ceilings are only 9' high . I have a hot water system with a direct vent gas fired boiler located outside of the finish room and it circulates water to a couple of old radiators in the finish room . It works pretty good and I don't expect it to be too difficult to move to my new shop.
I'd suggest a used furnace place far away and insulated duct the heat over to the booth. Hard to beat that for recovery. Also consider a variable speed booth fan so you can slow it down while venting the outgassing.
I do have the booth fan set up on a variable speed controller. When I'm spraying in the winter I spray with the fan at 45/60. When I'm just venting after spraying I drop it to 15 to 20/60.
This would be more just to heat the space during off hours when I am not spraying to keep the finish warmer around the clock and recently sprayed parts in a better temperature environment.
