So, pretty much the title. This is in the office of the (what I assume is) 70s-era condo I'm renting. It produces a TON of heat, which is actually kind of nice right now but also makes me worry it's going to explode. I assume that's pretty irrational considering how long the thing has been there, but I also see a scorch mark from presumably a bug flying into it and getting roasted. Should I be concerned about using this thing, or is it fine, and also does anyone know what it's called?
