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.

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

Here’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.

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