> When it’s cooling your house, it’s just a normal AC. But did you ever think “When it’s cold outside, why can’t we just turn the AC around and air-condition the outside, so it heats up inside?” Well, it turns out you can! And that is how a heat pump works. It just moves heat from the outside of your house to the inside, just by turning the air conditioning in reverse.

That's what most air-conditioning does in europe, it is also used for heating

  Probably location dependant but numerically I'd guess most ACs that Europeans have interacted with are in cars, which only very recently started using heat pumps for heat in the EV era.

    That dpends where you are in EUrope. Lots of housing have AC in the Mediterranean countries, and even in the famously AC-deficient UK pretty much every office building and supermarket will have AC.

  I wouldn't say most air-conditioning in Europe includes heat pump heating, in fact for most of Europe I'd say its not super common. Germany is in Europe. Only 4% of residential heating is from electrical sources, which is both heat pumps and resistive heat. 51% of household heating is from natural gas, 20% is from heating oil, and 18% is from district heating. https://www.statista.com/statistics/1189752/household-heating-sources-germany/ https://www.statista.com/statistics/1189752/household-heatin... Here's iea's residential heating sources in 2020. Italy (also in Europe) sourced 60% of its energy for residential heating from gas. Hover over electricity and see how low of a percentage it is in most countries. https://www.iea.org/data-and-statistics/charts/proportion-of-residential-heating-energy-consumption-by-fuel-source-in-selected-countries-2020 https://www.iea.org/data-and-statistics/charts/proportion-of...
