Heat pumps sound like magic since they somehow extract heat from cold winter air. Thankfully, the Guardian has put together a nice visualization of how heat pumps work. The gif above is not from their english language site.

Whereas gas boilers burn gas to produce heat, heat pumps do something more complicated.

In a cold winter, it can be hard to understand how these devices work.
