Another insight from the data is that the age of the property and the amount of insulation makes very little difference to the performance of the heat pump
This was a stand-out slide, showing a comparison between two identical heat pumps: one running low-and-slow compared to another running at high temperature for short periods.

💡Correct commissioning and control setup is very important
It's not a buffer, it's a volumiser. There's no harm in having extra volume on a system, however the primary reason I installed it was for testing purposes
Great stuff! @NewarkCylinders Heat Geek super cylinders are very good, my heatpump with this cylinder is one of the best performing systems on Heatpumpmonitor.org over the last 90 days, the standard Newark cylinders also look good and are very good quality
I've just documented in an
@openenergymon.bsky.social
forum post the various methods to read on-board data from the Grant Aerona HP290 heat pump, the data is not very accurate (ignore COP values 😂), but it's still interesting to log community.openenergymonitor.org/t/reading-on...
I've finally got round to editing a video from our EV camper van trip In January 😅

In this episode, we explore Portugal and experience a very dangerous campsite hookup issue 😬https://youtu.be/n9zQ2Ngftpg
Well done Isle of Man! I wasn't aware of this, installing fossil heating in new build houses is bonkers
Yes, BUT the Isle of Man banned fossil fuel heating systems for all new buildings.

So they’re not lax about regulations for everything.

Heat pump monitoring for last 12months via OpenEnergyMon. These 2 visualizations show the hot water and space heating uses as separate charts.
My two favourite things 😀
It's arrived! Thanks to Mars from Renewable Heating Hub for sending over a copy of his new book. It's a fantastic resource for homeowners considering a heatpump, or trying to optimise an existing system. I'm proud to have contributed in a small way 😀
Yes, we can do solar monitoring with our emonpi energy monitor with clip on CT's docs.openenergymonitor.org/applications...
Agree, I doubt Musk has much input into Tesla these days, it's mostly hardworking clever people, with a thick skin to put up with his antics! 🙄
Context: If you wanted an EV in 2015 the options were basically a 24KWh Nissan Leaf, Renault Zoe or a Model S, purchase cost aside there's absolutely no competition, this was the first long range EV, 10 years later it's still going strong & getting regular software updates!
There's not many 10-year-old cars with software this good, or 130kW+ charging speeds! The combination of autopilot and free charging make this the best road trip EV, Tesla was so far ahead of other manufacturers back in 2015, it's a shame they've lost their way a bit...

It still blows my mind how a heat pump can convert 2.2kW of electricity into 12.7kWh of heat! 🤯
We're on the verge of the heating season in North Wales, temperature is dropping to 11C, my newly installed Grant Aerona 290 heatpump has started trickling some heat in, impressive low modulation of 2.2kW (366W electrical) from this 9kW unit, COP of 5.7 at the moment 👍
It's good to be back #Ceuse 😃
Yes, it looks promising but that test was done in warm temperatures, I'm a bit concerned that in winter it may fall short of customer expectations, compared to a combi boilter, a conventional cylinder also enables utilising off-peak tariffs to reheat
Sure, if there's no space for a cylinder a Mini store is a good option, but customers would need to understand the limitations with flow rates and recharge time

Want mass heat pump adoption? Fix the running costs.

The electricity-to-gas price ratio is key. When policy makes electricity artificially expensive, the cleaner choice isn't the cheaper one. It's time to rebalance energy taxes, as this @thecccuk.bsky.social chart highlights.
