Not really? The best heaters are heat pumps which can under typical operation reach 300-500% efficiency (COP). Technically they aren't converting the electricity into heat, but for arguments sake here about heaters we only care about electricity consumed to heat generated.

In fact they are converting 100% of it, they are just also collecting and moving additional heat in the process.

Stop calling coefficient of performance "efficiency".

The heat pump takes input heat and just concentrates it. It turns out that the energy spent on concentrating heat also turns into heat, so you have a 100% efficient heater.

TIL, thanks, we mostly burn gas and coal
