Rather than argue with the naysayers all over the internet who’ll claim that heat pumps don’t work, the boffins at Octopus have produced a live dashboard to chart the online data they get from all the thousands of systems they’ve installed. This is a fantastic resource. Looking at the numbers for the fleet as a whole I’m pleased to say that ‘Rosy’ (my Cosy) is bang on the norm as far as performance goes. https://octopus.energy/cosy-heat-pump-performance/?utm_medium=email&_hsenc=p2ANqtz-92N1fVWdFAehre8wYictiCqGgrnpGeD9V5_EB3att0qPTctKB8kOeNTffe3KS1P7Gv41P9c_5XE4noQ-RqhVWDvpjwnA&_hsmi=131414226&utm_content=131414226&utm_source=hs_email
@christineburns Heat pumps totally work. Almost everyone in Finland heats their houses with one nowadays. Perhaps backed up by other systems, and we have nordic versions that can start up in extreme colds, but really it's just cheaper than anything else.

@gimulnautti @christineburns It's the same in NS (Canada). Almost every home has a heat pump now - mostly due to the fact that most homes used Furnace Oil which became brutally expensive, and expensive electricity making baseboards wasteful.

There is very little reason why someone wouldn't have a heat pump in NS now - unless they hate money or have some other cheaper form of heating.

The government gave them to people who couldn't afford to upgrade off of oil or electric baseboards - a huge win.
