I have come across a few stuck Honewell 3-port valves recently, so thought I would share a page i did about the topic. There valves are designed to be repaired, not replaced!

Done another YouTube on DT using some heatpumpmonitor graphs, the Heating Simulator and a radio.

Interesting. Michael Mosley research suggests cooler houses are good for us

For multi-zone houses. Why has nobody developed stats that 'encourage' zones to operate together. Even 'resetting' the diff. of all stats, after a compressor start, could 'entice' other zones to start. Surely a need for this? have I missed it?.

For anyone who has not seen it, this informative update from Glyn Hudson on his #ASHP in his old cottage is definitely worth a watch.

Can anyone help? I have the idea to replicate this 44 year-old pedal-powered #heatpump model for @centre_alt_tech 50th birthday 19th Aug. Where can I get a car AC compressor? Anyone know a friendly car breaker? any belt-drive compressor should do.

Looking forward to meeting people at the InstallerSHOW on Tuesday 27th. Birmingham.@Installer_Show.

Good to see this 10-year-old @Openenergymon GLCD still working well on a wind turbine today.

Does anyone know the thinking behind the Permitted Development ruling that only one ASHP within curtilage of a property?.

RT @TrystanLea: I've put together a little web app that graphs the @NationalGridESO 14 day wind and solar forecast, useful for working out….

Enjoying Sabine's no-nonsence honest videos on various topics

RT @glynhudson: Enjoyable evening last night at @EcoHome_Lab with @CarbonCoop thanks to everyone who joined in online for a discussion abou….

Check out "Heat Pumps — the first Million! (a participant-led conference)" @Eventbrite .Have got a ticket for this nice-looking event, Mon 26th June. Look forward to meeting people there.

Is heat pump cycling a problem or not? Here is a youtube with my thoughts and observations @Openenergymonitor

Finally put a 'type-in-the-values' version of my Simulators. Useful for quick back of envelope assessments of cylinder sizes/times, radiator sizes, flowrates etc.

It seems that the actual problem was a combination of unfamiliarity and dodgy buttons. jumping between 2011,2012,2021 etc with the up/down arrows is quite hit & miss, but doable. Working MUCH better now with lower curve setting and house reported warm enough.

@cchp @JeremyClimas many thanks for your helps. Graham Hendra has sorted me out I think. It just had to be solvable. easy when you know how!.

Anyone conversant with this Samsung ASHP controller (6 year old?). Its beaten me! Cannot puzzle out how to change the heating curve. It gives the 'no function' icon. What am I doing wrong? I have even read the instructions!!. no help

Aimed at those baffled by the concept of #heatpumps They defy logic!

Even if an immersion is at very bottom. its never low enough. Maybe overnight 'soak' would conduct heat down. Have seen immersions 1/2 way up doing legionella!. pointless!? De-strat circ pump (plastic) seems a good solution, then use much lower legionella setting. I use 50C.
