Katy King @katyking2.bsky.social · 01/03/2025Yes you are right - I guess it depends whether you think it’s realistic to see weather or load compensation correctly installed across the UK in the next ten years. Maybe I’m too pessimistic! 110

Katy King @katyking2.bsky.social · 26/02/2025I take your point that if customers also did pipework and radiator changes for low flow temps when they got a new boiler, they would be heat pump ready 110
Katy King @katyking2.bsky.social · 26/02/202560c is the lowest you could go as a blanket measure I think (without any consumer engagement or home changes). We’ve found recommending 60c usually works for most existing homes (I.e rooms heat up quick enough and savings are made) 210
Katy King @katyking2.bsky.social · 26/02/2025agree with the sentiment.. but an estimated 10 million boiler installations are anticipated over the next decade. May as well make they as efficient as possible... 110

Katy King @katyking2.bsky.social · 26/02/2025Households and businesses need to be better incentivised to make these choices through the impacts they will see on their bills. This can be done through rebalancing prices to remove policy levies from electricity bills. 160
