I’m using one in a 2x4x7 tent in a space that’s about 60 degrees during the day and 50 degrees at the night. It uses 200 watts on its high setting. I’ve noticed for my size tent it can raise the temp roughly 20-25 degrees above the surrounding ambient temp.
I put some 24”x45” drain trays in and I had to move it up from the floor to the first shelf to effectively heat the space and move the warm air around. Eventually I will hang it, but I wanted to see how it worked first.
I also don’t run it on a temp controller because the surrounding space I have is cooler, I just leave it on and have one of these (link below) for high heat and humidity exhaust. It’s quite a bit cheaper than the can fans and keeps up just fine, but if you need a carbon filter this fan wouldn’t work.
