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

If you dont want certain rooms heated you close the doors to those rooms. And place the heater such that the airflow goes trough the rooms you want heated.
Also the house should be heated evenly unless you have really poor isolation and that should be addressed way before the minutia of heat pumps gets discussed.
