How a heat pump works

A heat pump moves warmth.

Think of it as part of your home’s ecosystem: the air outside, the water in your heating, and the rooms you live in.

Electricity powers the process. Energy from outside helps warm your home.

Why does it sometimes change its tune?

Fans and compressors change their pace as the system works. Weather and demand can change how a heat pump behaves.

If something sounds unusual for your system, note when it happens and check the model’s manual.
