February is a great time to talk about… air conditioning. Otherwise known as air to air heat pumps, which can heat as well as cool your home, very efficiently. We have a big new report out today on how suitable air to air heat pumps are for British homes. The answer: quite a lot!

There are better ways to lower the cost of energy for households than a simple VAT cut @madgabes.bsky.social outlined recently - hopefully the Chancellor will tomorrow look to reduce electricity bills along lines of the tax-free measures @nestauk.bsky.social proposed www.nesta.org.uk/report/tax-f...

The Treasury is widely reported to be considering cutting energy bills, perhaps via a VAT cut. What's the best way to do this? We think the answer is to remove the taxes from electricity bills. Here is Nesta's proposal out for Tax-free Electricity: @nestauk.bsky.social

🏢 How are flats heated in England and Wales? 🏦 🔥 45% of 11+ storey flats use communal heating, at least half relying on fossil fuels 🏡 75% of low-rise flats (1-3 storeys) use fossil-fuel heating ⚡ 60% of high-rise flats use electricity for individual heating www.nesta.org.uk/project-upda...

Perhaps a better link to share with the details: mhclgmedia.blog.gov.uk/2024/11/21/w... Unless you can move the heat pump to be further from your neighbour’s nearest window, these changes are unlikely to help you I’m afraid.

🔥 Do we need to mandate the open protocol that all boilers and controls have to work with? 🔥 DESNZ consultation says boilers & controls just need to be compatible with 1 open protocol - so some will be incompatible with each other? I suggest OpenTherm as the mandated open protocol. Am I wrong?

Katy King @katyking2.bsky.social · 06/03/2025
Hi! If you have a combi boiler (no hot water tank) you can set the flow temp for radiators as low as you want. For tap water setting 42c is lowest you are advised to go Let us know how you get on!

Yes 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!

Fresh out the CCC oven – the Seventh Carbon Budget sets out a new trajectory for heat pumps. The new Balanced Pathway pushes back heat pump installations into the 30s – more realistic given current progress, but still ambitious.

I 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

Katy King @katyking2.bsky.social · 26/02/2025
60c 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)

Katy King @katyking2.bsky.social · 26/02/2025
agree 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...

The government is proposing all new combi boilers are supplied with a 60°C flow temp factory default setting by early 2026. Does anyone know if any existing boiler manufacturers already do this? Thanks! 🙏 @betatalk.bsky.social @joalsop.bsky.social

I’ll come back with some screenshots of charts, details on changes in pathways and so on in a bit… … but I think the big change in the 7th carbon budget is that the technology choices for net zero are now pretty clear. We need to stop arguing as much about technologies and electrify things quickly

Addressing barriers to heat pump adoption such as the price of electricity, lack of awareness, and misconceptions will also be crucial.

Katy King @katyking2.bsky.social · 26/02/2025
Households 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.
