For things that are "hmmm".
Rule 1: All post titles except for meta posts should be just plain "hmmm" and nothing else, no emotes, no capitalisation, no extending it to "hmmmm" etc.

You'd need a custom rig to do that, the exact hardware probably doesn't exist. Maybe someone has instructions for a similar DIY project out there.
I'm not gonna dissuade you from tinkering because maybe you'll invent something cool. There might be a better way to reuse the heat from a freezer or a fridge or an A/C, even if it's not to boil your water heater.
Maybe it could keep your plants warm in the winter, or heat your toilet seat, or your aquarium, reptile habitat, or hamster tank. Maybe it could warm up some blankets, our some pouches of sand or pebbles that you can put under your blankets. Maybe warm an incubator or a humidor or a dehydrator. The world is your oyster.
