Heat pumps are the most efficiency heating technology ever invented.

That's because they harvest, compress and transport pre-existing heat from the air, the ground or the water.

Compared to a gas boiler heat pumps deliver ~4x more heat for each unit of energy inout.

Cool that renewables have become the cheapest source of energy in the world just as a bunch of reactionary-centrist US pundits have taken up the right-wing "climate vs. cheap energy" framing.
