@plumbers_urban Thats what I work with full time for The last 14 years or so. So I See R744, R290,R600a etc everywhere 😁

[AndersJuul @juul_anders]

@BrianVad @martincollignon @NatuurenMilieu Are there any material availeble on a grid evaluation on what you state @BrianVad and are you aware if it looks different across countries in Europe. Would be cool if all heat pumps would be smarter and work to support the grid on a domestic home level

[AndersJuul @juul_anders]

@martincollignon @Mike_Sammon This is the way 💪

[AndersJuul @juul_anders]

@Mike_Sammon @homelyEnergy @OctopusEnergy This is where self learning heat pumps would be beneficial. It does not need be complicated but tracking over time DHW usages, COP at different ambient conditions etc. then hooked to forecasted electricity ⚡️ price and ambient the heat pump should be able of planing run pattern

[AndersJuul @juul_anders]

@Zarch1972 @ScottishGasMan @TomJHyde I need to get going with that Home Assistant stuff. Is it hard for a primarily Mechanical person?

[AndersJuul @juul_anders]

@ScottishGasMan @Zarch1972 Good explanation I will continue with normal heat curve I get from this!

[AndersJuul @juul_anders]

@drwave I commented as if you instead of running on thermostat always had the loop heating but ensured the flow temp was compensated vs. ambient. The you may save significant energy and comfort level go up

[AndersJuul @juul_anders]

@drwave Clear. I guess it is Hydronic. And the medium (water) either heated by boiler or heat pump

[AndersJuul @juul_anders]

@GeoBoon @Ainsdale_Gas I believe that the ambient conditions are specified in the standard they comply up against. This is then tested in a climate chamber by third party. In real life often all of this is much more dynamic. For the Vaillant I have a Arotherm Plus 10 kW and it performs well

@surface

[AndersJuul @juul_anders]

@jfi1963 No I did not know. 😖. Concerning. But indicates large potential 💪

[AndersJuul @juul_anders]

@Damon_BPHR Compressor starts since last time and average run time when running on compressors

[AndersJuul @juul_anders]

@ScottishGasMan @plumbers_urban @Ainsdale_Gas @glynhudson @theolodian @L__Bow @thatsamoray @PeterEastern @robertjwhitney @kenbone44 @heatpolicyrich @dan_grey @betateach @suburbanpirate In addition I may have a to large heat pump. The 10 kW have a fairly high minimum flow so I suspect the coil can not get rid of the energy while charging.

@ScottishGasMan @plumbers_urban @Ainsdale_Gas @glynhudson @theolodian @L__Bow @thatsamoray @PeterEastern @robertjwhitney @kenbone44 @heatpolicyrich @dan_grey @betateach @suburbanpirate Cylinder target temp 50 C start charging at 45C delta T on charging is 2K hence target flow temp is 52C

[AndersJuul @juul_anders]

@ScottishGasMan @plumbers_urban @Ainsdale_Gas @glynhudson @theolodian @L__Bow @thatsamoray @PeterEastern @robertjwhitney @kenbone44 @heatpolicyrich @dan_grey @betateach @suburbanpirate Yes. Difficult to read from manual. Where do I find information on what the heat pump actually does when selecting the ECO function?
By the way it ran fine and charged cylinder fairly fast still but it did in the end put out 60 C I noticed.

[AndersJuul @juul_anders]

@theolodian @PeterEastern @ScottishGasMan @plumbers_urban @Ainsdale_Gas @glynhudson @L__Bow @thatsamoray @robertjwhitney @kenbone44 @heatpolicyrich @dan_grey @betateach @suburbanpirate Agree. But after finding the eco function in DHW I now a blast at the home office following a DHW cycle real-time 🕺🏻

[AndersJuul @juul_anders]

@ScottishGasMan @plumbers_urban @Ainsdale_Gas @glynhudson @theolodian @L__Bow @thatsamoray @PeterEastern @robertjwhitney @kenbone44 @heatpolicyrich @dan_grey @betateach @suburbanpirate Found the DHW ECO setting in the VWZ MEH 97/6. Now will be interesting to see if better performance on COP in DHW mode

[AndersJuul @juul_anders]

@ScottishGasMan @plumbers_urban @Ainsdale_Gas @glynhudson @theolodian @L__Bow @thatsamoray @PeterEastern @robertjwhitney @kenbone44 @heatpolicyrich @dan_grey @betateach @suburbanpirate I do not See The ECO option in DHW mode. Arotherm plus, hydraulic station VWZ MEH 97/6 and sensoComfort 720. All manuals trawled. I only see option to limit compressor via noise reduction setting. May try that out 🧐

[AndersJuul @juul_anders]

@PeterEastern @ScottishGasMan @plumbers_urban @Ainsdale_Gas @glynhudson @theolodian @L__Bow @thatsamoray @robertjwhitney @kenbone44 @heatpolicyrich @dan_grey @betateach @suburbanpirate Uhhh difficult. I Think they have tried to make it simple. And I find often times good explanations. So. Not to bad. …. But would like more access to parameters in a simple way
