It’s honestly crazy that it took heat pumps this long to gain attention over resistive heaters when they’re literally just reverse air conditioners. Like, you could install a window AC unit backwards, and congratulations, you have the world’s first window unit heat pump. But noooo. Let’s spend copious amounts of electricity to generate trivial amounts of heat, or better yet, burn a toxic gas and give our children asthma. That’s soooo much better than adding a reversal valve to the technology we all already have installed in our homes, that’s been around since the nineteen-fucking-hundreds.
