CO2 heat pumps represent a promising future for cooling and heating. These systems use carbon dioxide as a refrigerant, providing an energy-efficient solution that can warm your home while heating ...

This transcript has been edited and condensed for clarity. The following sentence doesn’t make any sense, but is actually true: A heat pump can turn 1 kilowatt-hour, or kWh, of electricity into up to ...

The name "heat pump" is a bit of a misnomer, says Kevin Kircher, assistant professor of mechanical engineering at Purdue University who works with the Center for High Performance Buildings. "A lot of ...

In this last post of a mini– series about home electrification, I want to review some of the common specifications for heat pumps and go over how to use them to answer basic questions such as: – How ...

Sales of super-efficient electric heat pumps are rising, now overtaking sales of gas furnaces in the U.S. But what are heat pumps? And why do some call them a key climate solution? Here are the ...
