"While heat pumps are yet to become widespread globally, Hagemoen says they
offer several benefits compared with traditional heating. Low maintenance and
cheap to run, they work as both a heating and cooling system, and have a very
efficient conversion rate of energy to heat. They’re also light on emissions if
the electricity used is renewable. “If you want to be independent of gas, you
need other solutions,” says Hagemoen. “And when it comes to electricity, heat
pumps are hard to beat.”
Heat pumps, which can operate at external temperatures of -25C (-13F) and
provide hot water at 65C (149F), come in several forms. The most common is the
air-to-air pump, which looks similar to an air conditioning unit. It sucks in
air and distributes it over a system of tubes filled with a refrigerant liquid,
which warms and turns into a gas. The pump compresses the gas back into a
liquid to release the stored heat, which is spread through radiators or
underfloor heating, working like a refrigerator in reverse.
Nick Eyre, professor of energy and climate policy at the University of Oxford
and director of the Centre for Research into Energy Demand Solutions, says that
heat pumps are one of the most effective options to decarbonize heating
systems."
