Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

It's not possible for a heat pump - or anything - to even be 100% efficient, let alone 400%. Efficiency is measure of how much of the input energy gets converted to useful output energy, and since heat pumps don't actually create heat the useful output is the compressor's ability to pump refrigerant about. The Coefficient of Performance - the ratio between energy put in and useful work done - is 400% for a heat pump (give or take).
๐ค ACKSHUALLY
Heat pumps create a fair bit of heat due to friction and electrical resistance in the compressor.

Energy is conserved. It is converted from another form of energy, or in this case mostly transported, not created.
Heat and energy are not the same thing, scrub. You can create heat no problem.
Fuck me, every time with this "useful heat" bs...
