Finally! Nearly a quarter of new UK homes now have heat pumps—big progress since we highlighted the fossil fuel problem with Ben Webster at openDemocracy in 2022. Next step: fully implement the Future Homes Standard and end fossil fuels in new builds.

Good article here on how Scandinavian countries have embraced heat pumps moving almost entirely off fossil fuel heating. In short: - grants - lower electricity price - carbon tax making other options expensive - a ban on fossil fuel heating. If this worked for them, it could work in the UK too.

NEW: A UK firm intends to start making this new form of "thin" triple glazing with a 0.5mm centre pane of super strong glass developed by Corning. It could let people to swap out their double glazing for triple glazing - without changing their window frames. www.thereengineer.pro/p/can-this-t...

If Western nations want to keep pace with China in the clean energy race, many well-meaning regulations and legacy approval processes will need to be streamlined or reimagined. Speed and scale are critical. Graphic by Insider.

🚗💨 EVs are holding up better than combustion cars, says ADAC. In 2024, ICE cars aged 2–4 years were 2.5x more likely to break down than EVs. EVs on the road ↑ 97% EV breakdowns ↑ only 46%

It's a myth that "hydrogen combustion produces only water vapour". Burning hydrogen results in harmful NOx emissions. In urban areas this becomes the dominant source of NOx pollution if we switched to hydrogen for heating. Shocking to see H2Heat project financed by the EU peddling such untruths 👇

People often take the view of 'waiting until the boiler packs in' but this demonstrates that the best time to swap is when it's financially and practically convenient for the end user. Plus, you'll maximise the savings the sooner you do it.

Does it make sense to rip out a new gas boiler and replace it with a heat pump? From carbon perspective yes: Replacing a new gas boiler with a heat pump in the UK cuts emissions by 77-86%. This includes embodied emissions from manufacturing. A heat pump offset its embodied carbon after 13 months.

This, it needs repeating aggressively and repeatedly. Gas drove up electricity prices in UK, not renewables or wretched Net Zero.

Renew your EV vehicle tax before next month, while it's still free.

A work of art.

It's insane that politicians will actively try to spoil progressive developments which will benefit the whole world just for the sake of a bit of political gain. Pathetic. When will we embrace a political system which seeks to benefit the masses rather than just tribal point scoring?

Electrification is efficiency. With clean electricity, we cut major inefficiencies, lowering overall energy demand in a decarbonized world. 🔗 sustainabilitybynumbers.com/p/electrification-energy-efficiency

protonsforbreakfast.wordpress.com/2025/02/20/u... Just letting you know about some forthcoming talks about Retrofit and heat pumps in the Richmond and Hampton area.

This is fantastic news! The problem is if we tell too many people, they may assume it's job done and down tools!

Time to use Amazon like they used to use brick-and-mortar book stores!

There is no country/zone with a) high prices and low carbon emissions or b) with low prices and high emissions. The higher the carbon emissions from electricity generation in 2024, the higher the prices and vice versa. HT Esko Heinonen

A reminder that electrification remains the single most important route to reducing emissions. Increasing the rate of transition to heat pumps is key to that. More legislation is required to limit gas installations in existing properties urgently.

Great thread explaining how our grid structure is costing us money and perpetuating the use of fossil fuels to generate electricity.

I've written some musings on seeing outside your bubble. open.substack.com/pub/llewelly...

🏡 Many people are interested in transitioning their homes to low-carbon heating but aren't sure where to start. We've created GetAHeatPump.org.uk with The MCS Foundation to provide free, impartial advice on heat pumps to help more people make well-informed choices about their home heating.

"It's actually really quiet [...] it keeps the house warm, even in last weeks -5C, our house was a toasty 21.5 inside" Octopus customer Conrad loves his heat pump & busts some myths:

Often we miss the point when evaluating heat pumps, that they ultimately reduce the energy demand on the energy networks. Over the course of Nov, Dec and Jan my total energy usage has reduced by 40% a month. It's also a bonus bonus that it's saved £150 during this time. #heatpump

An excellent podcast series for those curious about entering the world of heat pumps or perhaps those starting to think about their next heating system upgrade. Bite size episodes to help educate and inform.

What are the alternatives to the widespread adoption of heat pumps, if we want to stop using gas boilers? That's our topic in a new episode of the Happy Heat Pump Podcast 😃 podcasts.apple.com/gb/podcast/t...

How to find oil. Seismic acquisition involves air guns firing into the sea from large vessels every four to 10 seconds, 24 hours a day, seven days a week, until surveys are completed. The blasts create loud sound waves that can penetrate more than 10km beneath the seafloor. Isn’t that delightful.

Current issues with heatpump installations: good write up by @trystanlea.bsky.social on the @openenergymon.bsky.social forums community.openenergymonitor.org/t/over-sized...

Fair play @neilatkinson.bsky.social, you've given that some thought! Sounds interesting

Really interesting. Mitsubishi ecodan 8.5kW. Left of the line it's running in Auto Adapt mode with temperature differential turned off. Right of the line it's running with the flow temperature set to 33 (the target temp based on the curve and external conditions). Cycling at around 2 per hour.

Delighted to be taking part in the #visitaheatpump scheme. A chance for people considering a move into the cosy world of heat pumps, a chance to talk through any questions they may have. They can see and hear the unit in operation and learn more about the installation process.

Decent offering from Tomato energy for homes with a heat pump compared to @octopus.energy Cosy. Feels like Octopus are giving with one hand and taking with the other at 40p kWh during peak times! Add an EV to Tomato and it's even cheaper. No option to combine with Octopus. #heatpump #smarttariff

Breaking news! 'Family has faulty heating system' How many articles are run on the cost of an oil heating system or oversized boilers leading to massive gas bills? I wonder how many articles #surreylive have run on carbon monoxide leaks? #heatpump

Really shocking and saddening to read this. We knew it was happening but this highlights a depressing anti net-zero stance being taken for what purpose? Newspapers playing games over an incredibly serious matter for every human on this planet. #netzero #climate

What are your thoughts on this @chiefgeekad.bsky.social ?

Disturbed to learn that the gas boiler ban is being scrapped. Majority of people renovating a property stick with gas as It's seen as the easy option and familiar. The only way to change this is through legislation - the government has bottled it! #heatpump #fhs www.theguardian.com/environment/...

Happy New Year! Let’s start it with some good news from the UK: One in five cars sold in 2024 was battery electric. 6 years earlier it was just 0.7%. www.theguardian.com/business/202...

+++NEW ANALYSIS+++ UK electricity was the cleanest ever in 2024, with emissions per unit falling by more than two-thirds in a decade Highlights: 🏭end of coal power after 142yrs 🔥fossil fuels at record-low 29% share 🌄renewables at record-high 45% www.carbonbrief.org/... 1/9

I've been able to use @openenergymon.bsky.social to optimise the performance of my newly installed Ecodan 8.5kW during its first winter. Ecodan Auto Adaptive proving to produce better performance compared to pure weather comp during similar outside conditions.
