Are you heating your sign shop or your house with this heater, (you mentioned upstairs).
What type, size, brand of heater is it?
How is it vented to the outside for combustion air and exhaust?
Thanks
I'm heating both, and also have a smaller stove in the kitchen area that helps with the downstairs. My shop is an enclosed two car garage, aprox. 30' x 30', and the upstairs is approx. 1500 square feet. It's vented via a double-wall 6" stainless chimney up through the garage ceiling, the upstairs and the attic to the roof....that boils down to approx. 8 feet of black pipe and 20 +/- feet of stainless.
The stove shown in the photo is a "Fire Chief" FC1100 with the side and top panels removed. The blocks are dry stacked around the stove and are secured with straps screwed to the frame of the stove....much like the way they lay up brick on a cinder block wall. Every one in a while, I have to remove the blocks above the stove and re-position them since the cooling and expansion tends to move them around. The blocks atop the stove rest on the side blocks so there is absolutely no weight resting on the stove.
Here's a link for the stove:

I moved that particular stove out a couple of years ago and put in a smaller one made by Johnson Energy Systems (1980s vintage) and it seems to work better for some reason. I think it has a lot to do with running the smaller stove harder...rather than letting a larger stove smolder. Once the blocks get warmed up, it's quite easy to keep the place warm with just a small fire....it's kinda like building up momentem in a flywheel, so to say.
The bummer is that the Fire Chief cost me over two-grand eight years ago, and I picked up the Johnson for $50. Believe me, I'm taking it with me if I ever move.
The dog door is only ten feet away and the draft from that helps with the "make-up" (combustable) air.
Air is such a poor conductor and retainer of heat, hence the reason for the concrete blocks. My next step will be trying to engineer a boiler to sit atop the concrete blocks and pipe that into the cooler areas of the downstairs.
It's a sad tale when the dogs get the warmest room in the house.
