Comment on The more air conditions in an area the hotter becomes around it. In turn increasing the demand for AC. Talk about infinite money glitch.

A heat pump can heat a home by more than the energy in the electricity it uses. It’s more than 100% efficient at “converting electricity into heat in your home”. It does that by not actually covering electricity but by moving heat, and it is less than 100% efficient at converting electricity into motion, and introduces some waste heat

The efficiency of a machine isn’t measured at how effective its job is, but how efficiently it does that job. If it moved heat without producing any waste heat, it would be 100% efficient. If it produces any waste heat at all it’s not 100% efficient. No machine can ever be more than 100% efficient. That would violate the laws of thermodynamics.

  Hence why I clarified what it was efficient at doing.
