Hey, /out/, I'm a bit of a faggot and I mostly just camp in my (pretty big) backyard. I've been using these things in a firepit to chill out for a couple hours every day, too.
The manufacturer says they're not for cooking stuff, but I was wondering: Would it be safe to cook stuff that doesn't require true cooking (like beans), just reheating, in a lidded pot over them? I can't use real wood because of where I live & I have asthma that makes real wood smoke absolutely murder me, whereas the wood-dust/wax smoke these things give off is totally fine on my lungs, bizzarrely.
Here's the manufacturer's page if it's any help:
