I always figured that Hot tiles were actually really big stoves for the Empire (Do you know how hard it is to get citizens to eat roach queen spawn, every day?), but I'm fairly certain that all stove tops have a dial to adjust their intensity, like when you want your roaches simmered, instead of flashfried. The basic game mechanic is that every time you walk over it, it rotates between off, low heat, medium heat, and high heat. This gives the number of turns it takes to kill monsters after they have stopped moving (infinite, 5, 3, and 1 respectively) as well as the overall color of the tile.
Puzzle potential is easy. You start off with a bunch of hot tiles off and roaches to spawn at way more than 30 a cycle, and you have to figure out a way to get the hot tiles on to make it possible to start killing mothers. Or you can have timing puzzles, wherein you need to trap a roach queen running away from you on a hot tile of a certain warmth to prevent a brained roach from killing you.
Alternately, or in addition, monsters, especially rock golems, are heat resistant, and so must be trapped on a hot tile that is on high to be killed. This could lead to a dial you could only hit once (with eg. trapdoors) and would need to get all of your golems packed in efficiently, otherwise the room wouldn't be completable.
Note, I assume you can set the initial temperature of the hot tiles, which the dial will pick up on and use as it's temp.
