This is a short but clear article about the benefits.

QuoteRetrofitting every house in the UK to net zero standard by 2050 will require replacing all gas boilers, mostly with heat pumps. The target rate is 600,000 a year by 2028 – but in 2022, fewer than 60,000 heat pumps were installed.

As the government prevaricates over asking manufacturers to make more heat pumps, debate rages over whether they are a wise replacement. A recent article in The Times, for example, claimed that heat pumps do not work in cold Scottish winters.

In fact, heat pumps have been tried and tested around the world. Apprehension about them in the UK is down to the fact that most people are unfamiliar with them.

I love my heat pump, it makes a tank of hot water very quickly and takes its power from my solar, at this time of year it's basically free to run.

The real test will be heating in the winter but I'm not too concerned as I have a very well insulated house and the pump was fitted by people that actually knew what they were doing.

It's very clever tech, honestly probably too clever for the people that spend all their days complaining about them
