What's an "inefficient electric heater"? Is that a device that generates more light than heat?
Surely all the energy you put into any machine is eventually going to turn into heat? Hmm - perhaps there are heaters that generate heat mechanically, and the resulting losses are sonic.
- nicoburns 5y agoThere are electric heat pumps which move heat from the ground into your space which use drastically less energy than electric heaters that convert electricity into heat directly.
- denton-scratch 5y agoSure; but that's because a heat pump has the potential to be > 100% "efficient" (which isn't real efficiency, in the thermodynamic sense).
