Sales are growing so quickly that some installers wonder whether heat pumps could even wipe out the demand for new air conditioners in a few years and put a significant dent in the number of natural gas furnaces.

So he's not talking about efficiency.

Please explain to the down voting morons why 100% efficiency is impossible.

If everyone in the world had an engineering degree the distinction might have been important, but complaining about it in this context is just pedantic.

I really don't agree with that. "Baseboard heaters are 100% efficient" is an objectively false statement. And efficiency is a very common and basic concept that doesn't require a degree to understand.

I think instead of just dismissing it as pedantic, people could learn something.

Maybe try looking it up.

Electric resistance heating is 100% energy efficient in the sense that all the incoming electric energy is converted to heat

Hereโ€™s how to compare baseboards to heat pumps.

Baseboards create heat through resistive loads. As all the energy creates heat, you can say they are 100% efficient, but that is misleading if you take that to be good.

Heat pumps simply move heat, in either direction, to heat, or cool, and they do this using 1/3rd the energy.

Todayโ€™s heat pumps work at much lower air temperatures, can also use ground loops, or exchange heat from water bodies. #HeatPumps
