If a machine is never 100% efficient transforming energy into work because part of the energy is converted into heat, does it mean an electric heater is 100% efficient? @showerthoughts@lemmy.world

    But there’s a flip side to that as well - if you’ve got heat pump heating your whole home but you only really need to heat 1 room, you may be “wasting” a good chunk of that bonus efficiency.
