We put ours in a box plus put a fan in it. Also keep it in the corner out of drafts. When I open it, I open it through the windows, not the whole top.( Yes, I get burned slightly from touching the element.)
I found when turning off the turner for lockdown, it takes a wee bit temp adjustment to compensate for the lack of fan motor heat.
Oh, and we also added foam insulation between the two halves.
When I had it running for two months straight this spring ( with a hatcher for lockdown), I didn't touch the dial in weeks. There was some fluctuation, but not more than normal chicken!
