How well can heat pumps work when designed, installed and commissioned well? This is one of the main questions we are exploring with https://t.co/xoKcrLjSq8, we now have 36 systems with H4 monitoring boundary with 1 year of data, average SCOP/SPF is 3.9 🥳🧵

📸 New Feature: https://t.co/8TWDNPOlS7 now supports uploading photos of systems 😃

We've started stocking heat pump specific Type-B RCDs and associated Doepke switch gear which meet the all the manufacturer requirements including Vaillant > 1kHz tripping characterises https://t.co/jhCPRRC2aw

This system has full @Openenergymon independent Level 3 Monitoring, data is publicly available on HPM here: https://t.co/17iVCPYc9c

Thanks to @tom_bray for this excellent video about @Openenergymon HeatPumpMonitor 😀 👏 https://t.co/f5CwrtA8pr

Another new blog article up on the site. This time we look at the @MixergyLtd claim that all 250L of my cylinder is available as usable hot water. This deep dive would never have been possible without @Openenergymon 👍 Comments welcome. https://t.co/T66j4dZBQm

It's great to see @Openenergymon monitoring data being used to test some interesting innovation 📈

We now have a map view on https://t.co/rchtPEOOiL 🥳 📌 Find some of the best heat pump installers in your area, based on real world performance data 🌎 Explore examples of real-world heat pump performance data in many countries worldwide @Openenergymon

Just spotted this Redit post, a Raspberry Pi with one of our RFM2Pi receivers has been running our Emoncms software data logging non-stop for 10 years! 🥳 https://t.co/dz0VFXdt5U

I've been updating my @home_assistant wall-mount display, this is integrating data from @openenergymon @OctopusEnergy @OpenEVSE and @OpenVehicles 😀

Lots of useful info here on how to get the best performance from a Vaillant Arotherm+ heat pump, with help from our Level 3 heat pump monitoring data 🤩

Delighted to have been ask to speak at this event. The talk will be mistakes made and lessons learnt across the 3 winters with our Vaillant heat pump. @Openenergymon are also speaking, so will be a good event. Then heading to Installer Show on the Tuesday. @energystatsuk

The emonPi2 and emonTx V5 electricity monitors are available from our web-store

Here's an updated installation video for the emonPi2 and emonTx V5 for electricity monitoring using clip on CT sensors

Looking forward to this event, Trystan Lea and I will be attending from @Openenergymon and giving a presentation on the data and learnings from https://t.co/yWHpjjq3Oo. Tickets are still available

This cost includes remote support and lifetime data logging. By default, monitoring data is private, optionally you can choose to contribute to the open dataset of real work heat pump performance by making it public on https://t.co/fjdNHa0gPh 🙏

We've managed to reduce the price of our popular Level 3 Heat Pump Monitoring Bundle 🥳 - up to 10kW £462 +VAT - up to 17kW £539 + VAT https://t.co/37ZYte8ajJ

For this reason our Level 3 Monitoring Bunde uses independence MID billing grade heat and electric meters to monitor total electric input and accurate heat output with DT temperature sensors inside the primary pipes and including energy lost to defrost

These errors can be significant resulting in more than whole COP figure discrepancys, plus or minus, even the same make and model of heatpump can have discrepancys due to manufacturing tolerances e.g SCOP 6.1 vs 4.88

Examples of onboard monitoring inaccuracies include: - not including defrost energy - not including circulation pump(s) - not including booster heater and immersion - temperature sensing errors resulting in inaccurate DT measurement

For this reason we don't by default display onboard monitoring data on https://t.co/fjdNHa0gPh, it has to be enabled under the 'Other Metering' checkbox
