"Heat pumps are becoming all the rage around a world that has to slash carbon
emissions rapidly while cutting energy costs. In buildings, they replace space
heating and water heating – and provide cooling as a bonus.
A heat pump extracts heat from outside, concentrates it (using an electric
compressor) to raise the temperature, and pumps the heat to where it is needed.
Indeed, millions of Australian homes already have heat pumps in the form of
refrigerators and reverse-cycle air conditioners bought for cooling. They can
heat as well, and save a lot of money compared with other forms of heating!
Even before the restrictions on Russian gas supply, many European countries
were rolling out heat pumps – even in cold climates. Now, government policies
are accelerating change. The United States, which has had very cheap gas in
recent years, has joined the rush: President Joe Biden has declared heat pumps
are “essential to the national defence” and ordered production be ramped up.
The ACT government is encouraging electrification of buildings using heat
pumps, and is considering legislation to mandate this in new housing
developments. The Victorian government recently launched a Gas Substitution
Roadmap and is reframing its incentives programs towards heat pumps. Other
states and territories are also reviewing policies."
A few years ago we replaced a fireplace with a reverse cycle air conditioner,
then when we replaced our clothes dryer the new one is also a heat pump, and
finally this year we replaced our gas hot water heater with an electric heat
pump. They are great!
