After two years of research and a lot of help from Twitter, I finally have a heat pump!

Lots of thanks to @jesseb4me, @Merrion, @jimmybb, @techpoodle, and countless others I’m sure I’ve forgotten.

@DanNeidle I generally agree with you here @DanNeidle, but it would be interesting if they cut it on electricity and not gas to reduce to ratio between gas and electricity prices, which would help encourage the uptake of heat pumps, for example.

@Ewbank_1 @EVPuzzle @johntisbury @betateachpod I posted about it here:

@Ewbank_1 @EVPuzzle @johntisbury @betateachpod We had a Daikin 4-port installed in late 2023. It’s provided all of our heating since then. 1908 Edwardian end-of-terrace house. It’s transformed the comfort of our house. Happy to talk!

@WinterSling @renewablewriter I can now tell my fellow local residents about my A2A HP install without fearing one of them going grassing to the local authority :)

@UbnTricky @HMRCcustomers Not only have @HMRCcustomers closed it a day early, I've just looked back at a screenshot I took a couple of weeks ago to realise they presented the deadline as 25th April, not 5th April:

@renewablewriter @dan_grey @OctopusEnergy I want to be clear - these aren't tight terraced homes. My parent's home is an ex-council house built in the 60s. They've built a side extension, but the neighbours at the start of the next terrace have not. The gap between the homes is far greater than most.

[Tim Mortimer @timothymortimer]

@renewablewriter @dan_grey @OctopusEnergy Hi Matt. I'm pleased the 1m rule has been scrapped, but how does having the flexibility to site your heat pump nearer to your neighbour's boundary help you when the noise restriction is to do with the distance to the middle of the nearest liveable room's window?

[Tim Mortimer @timothymortimer]

@renewablewriter @dan_grey I strongly dispute this. My parents just had a heat pump installed by @OctopusEnergy. They needed planning permission because of the noise measurement. The affected property was on the end of the next terrace along, with a wide enough of a gap for them to build a side extension.

[Tim Mortimer @timothymortimer]

@levelsio @manoj_ahi I do the same. I used to keep a lot more in the company, but there’s always the “what if I get sued to oblivion?” fear.

[Tim Mortimer @timothymortimer]

@IrishRainforest I did the same last November. I haven’t looked back:

@EssaysConcern @L__Bow @energysmartwv Sounds about right - it’s a bit more for me as I live in an 1908 property with not the best air tightness and insulation.

[Tim Mortimer @timothymortimer]

@L__Bow @EssaysConcern @energysmartwv It’ll drive up interest and expertise and the supply chain, pouring money into ever improved options and technology, which I suspect (but obviously don’t know) will help people make more 100% switches over time.

[Tim Mortimer @timothymortimer]

@L__Bow @EssaysConcern @energysmartwv Household specifics aside, I think the politics of it all is hard to ignore. An expansion of A2A installations without the associated hassle of radiator upgrades and more importantly, HW tank siting, will go a long way towards normalising HPs amongst the general population.

[Tim Mortimer @timothymortimer]

@EssaysConcern @L__Bow @energysmartwv Taken together, I’ve made a massive dent (80-90%) in my gas usage, and I’m subsidising the gas network still (personally sad, but good for the system). I can now think about and fund the removing of my range oven with gas stove and gas DHW combi separately.

[Tim Mortimer @timothymortimer]

@EssaysConcern @L__Bow @energysmartwv There’s also individual blockers. Decarbonising my heat was easy. I did it with A2A in the end, but a split A2W system could have worked too. Hot water on the other hand is trickier. For some, a heat only system for now might be all they would consider? It’s better than nothing.

@graeme_cobb @theolodian @veloceuraptor @Everyth1ngElec Here’s the story of my A2A install if you’re interested:

[Tim Mortimer @timothymortimer]

@Merrion @MrSimonBennett I thought those plant sales would make the cost worthwhile?

[Tim Mortimer @timothymortimer]

@ewan_chamings @theolodian @L__Bow @NoPoke @Protons4B Sounds like a good idea if that works for you! I went for a 4-port, and it covers my whole house: https://t.co/Kb9ZaAQErv

The downstairs bathroom can get a little cold. We're going to put a wall mounted electric heater in there for when we're having baths.
