It's been 1yr since I installed a Grant HP290 heat pump and @newarkcylinders.bsky.social in my house! 🏠 Space heating SCOP 4.8 🚿 DHW SCOP 4.3 📊 Combined SCOP 4.7 💰 Running cost on Agile with battery: £567/yr 🛢️ Previous oil boiler would cost £2k to deliver same heat (72% saving)

DID YOU KNOW: The top 3 DHW performers on @openenergymon.bsky.social right now are all using Newark Cylinders' @heat-geek.bsky.social Super Cylinders. Three different heat pumps, three different installers, 4+ COP across the board newarkcylinders.co.uk/products/hg-...

I really enjoyed recording this podcast, it was great to chat to Gregg about @openenergymon.bsky.social all the other fun stuff e.g heat pumps and EVs 😀 This was recorded at the @fullychargedshow.bsky.social Everything Electric show, which explains why I was losing my voice!

Q1 2025 heat pump stats: Energy in: 2,553 kWh @ 16.87 p/kWh avg Heat out: 8,598 kWh Avg COP: 3.37 Avg cost of heat delivered: 5.01 p/kWh [~31% cheaper than 85% efficient gas boiler @ 6.19p/kWh] Monitoring by @openenergymon.bsky.social My system details here: heatpumpmonitor.org/system/view?...

Studies that are already out of date by the time they get into circulation is part of them problem. Live results from @openenergymon.bsky.social for real-world heat-pumps illustrate what is possible, right now: heatpumpmonitor.org We've achieve a COP of 4.1 this week here in rural Scotland.

30kW SolarEdge PV and 65kWh of GivEnergy Commercial battey system is now up and running, with @openenergymon.bsky.social monitoring 😀

Heat pumps are on site! Our shared office space will soon be heated by 2 x 16kW @viessmanncs.bsky.social ASHPs, of course with @openenergymon.bsky.social monitoring, no more LPG 😀

Proud to have played a small part in this, heat pump monitoring using @openenergymon.bsky.social has resulted in £100/month bill saving 👍

This is a story about what you can learn when you start tracking your central heating system. And for heat pump owners in particular, that data could be transformative.

I really enjoyed this episode of the @TransitionShow.mastodon.energy.ap.brid.gy podcast with @richardlowes.bsky.social, thanks for the @openenergymon.bsky.social heatpumpmonitor.org mention, "brings an element of fun into heatpumps" 😁

Energy Transition Show@transitionshow.mastodon.energy.ap.brid.gy · last yr.

Heat is the largest end-use of energy, contributing 40% of global CO2 emissions. And heat pumps are one of the cheapest and most versatile ways of decarbonizing heating. In Ep. 243, heat pump policy expert Dr. Richard Lowes outlines how to design policies to encourage the adoption of heat […]

I am excited that one of my heat pump installs is now on @openenergymon.bsky.social Simply the best heat pump monitoring software. You can view the live data here. emoncms.org/app/view?nam...

Agree! To me I think we should all have @openenergymon.bsky.social, MCS should improve the minimum scop from 2.8 to 3.6 and then consumers should have better protection to get installers back to fix problems if they aren’t meeting these standards

Here's a video about an interesting ASHP installation I was involved with in a solid stone cottage, the combination of insulation, air tightness, UFH and MVHR has made for a very efficient low-cost heating system with a SCOP of 5.1 for space heating 😀 📈 youtu.be/YouOLThHSNk?...

This is part of a big electrification and decarbonisation project for the building to remove deoendancy on LPG, reduce running costs and increase energy security; this will involve 2x 16kW Viessmann ASHP cascade, 69kWh of GivEnergy storage, 30kW of PV and @openenergymon.bsky.social monitoring 😀

I've been helping out on a solar PV installation on our @Openenergymon shared office space, it will be a 30kW SolarEdge array! Today we fitted the rails and got the first couple of panels in place 😁

THE NUMBERS ARE IN! It’s been a full year since @skillbuilderuk challenged us with a heat pump system that may have proved they don’t work in UK housing stock A typical UK property that was nearly 150 years old with uninsulated solid brick walls and a heat pump that cost a 2 x more than the boiler

We've added Octopus Cosy and E.ON Next heat pump tariffs to HPM, the combination of smart tariffs and high performing heat pump installation can deliver cost of heat at less than 4p/kWh! 🤯🤑
