Few - Many electric cars use inefficient electric heat that draws as much battery power as the traction motors. Some have more efficient heat pumps, but not all. Regardless, heat is no more instant in an EV than a conventional vehicle.
- sitkack 9y agoNot to be technically correct, but electric heat is 100% efficient.
- sgc 9y agoA heat pump can be more than 100% efficient in the sense you seem to be talking about. It transfers heat from one area to another, and can bring in more heat to a space than the energy used could produce in heat through a resistive heating element. https://en.wikipedia.org/wiki/Heat_pump https://en.wikipedia.org/wiki/Heat_pump
