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

What makes a heat pump install efficient? 📈

I presented the data-backed insights from @openenergymon.bsky.social heatpumpmonitor.org at a recent CarbonTrust webinar.

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

Abigail Dombey @abigaildombey.bsky.social · 24d

Yes, BUT the Isle of Man banned fossil fuel heating systems for all new buildings.

So they’re not lax about regulations for everything.

Isle of Man Govemment
NET ZERO
ISLE OF MAN
A QUICK GUIDE TO THE FOSSIL FUEL HEATING SYSTEM BAN
From 1 January 2025 it will be illegal to install a fossil fuel heating system in a new building.
Heating our homes is one of the greatest contributors to the Island's greenhouse gas emissions. It is imperative to decarbonise our buildings if we are to reach net zero by 2050 and new homes and buildings will lead the way in this transition.
WHAT BUILDINGS ARE AFFECTED?
The ban will apply to:
• new domestic and non-domestic buildings
• a new extension.
The ban will not apply to:
• fossil fuel heating systems in existing buildings.
• the use of an existing fossil fuel heating system in a new extension by the installation of pipework and/or
radiators connecting a new extension to the existing fossil fuel heating system.

KEY DATES
1 January 2024
Building Control refused on new buildings containing a fossil fuel heating system
Applications for Building Regulations Approval that contain a fossil fuel heating system will not be approved from this date.
1 January 2025
•Installing a fossil fuel heating system in a new building will be BANNED

This means you will need to make an amendment to your building control application and reapply for planning approval for your development.

FOSSIL FUEL HEATING SYSTEMS BAN - VISUAL GUIDE

Installation of fossil fuel heating system in new building - NOT PERMITTED
Use of existing fossil fuel heating system in now extension - PERMITTED
Installing a new or replacement fossil fuel heating systern in an existing building - PERMITTED
Installation of fossil fuel heating system in new extension - NOT PERMITTED

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...

I would recomend David Moss from OpenHouse Renewables based in Aberystwyth, he often works with John Cantor share.google/Z1wGKRVFlO9S...

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! 🙄

Glyn Hudson @glynhudson.bsky.social · Sep 13

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!

Glyn Hudson @glynhudson.bsky.social · Sep 13

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! 🤯

Glyn Hudson @glynhudson.bsky.social · Sep 8

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 😃

Glyn Hudson @glynhudson.bsky.social · Aug 28

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

Glyn Hudson @glynhudson.bsky.social · Aug 28

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.
