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 Would love to see how they propose to install them for a top floor Glasgow tenement flat.

@scotdowser
I'm in Canada, don't know exactly what a Glasgow tenement flat is, but you can hang the slim condensers from the side of the building. I can see how this my be a policy or even political issue, but it is a solved technical problem.

@christineburns

@dmaonR @christineburns Yeah, that bold-on solution is never going to work on Glasgow's Victorian buildings, many of which are listed. I know the Council have been experimenting with roof-mounted ASHPs on a couple of buildings, but as many tenements have multiple owner/occupiers, retrofitting them all is probably an impossible, certainly monumentally expensive, task.
