Post and beam

Understood. I have a 5kw Vaillant arotherm. Will give this 'wide open' strategy a trial.

Interesting strategy, my design was presented to me with each of the 11 circuits assigned a flow rate. I do not have a buffer, well i dont think so. I have a RED pressure vessel and a white one in my cylinder cupboard. All discussions with the installer made it clear i wanted a single zone downstairs for the UFH. WC and as simple as possible. Thanks for the response by the way.

Apologies guys this is an ASHP related question. MODS: can this post be moved please?

When adjusting the flow can anyone confirm its the RED disk shown by the Red line. I guess so but there is that other disk just below it( blue line)

I started with cable ties and the Ubbink plastic mounts for my 90mm Ubbink green ducting. Neither are up to the job of keeping it where you want it, not if you like nice straight runs anyway. There is a curve to this stuff from when it was rolled up. This needs a lot of persuading to behave itself.

If i were going for full on Passive house i would not entertain any contractor that did not have a long track record of doing so. And a list of satisfied customers. Although i am very happy overall with my new house (not passive) i can say that not a single contractor actually did exactly what they said they would.

In my case and in the village i now live in, the 4G is patchy and 5G non existent.

Thats what the 5.7 is, well its 5.5 for today actgually.its todays daily values so far. If i manually take the heat generated for both water and Heating and divide by the electrical energy used i get 5.5

Understood. So that is our reference. For my installation there are very simple controls and no un necessary pumps buffers or anything. So i am going with the belief that my values from the 'Vaillant connect' app are likely to be less than the 20% potential margin of error. So if i say that 10% margin of error is reasonable i am still happy enough with my current running value of 5.71

From a purely empirical point of view, which method is the reference? Or for that matter any other method. How does anyone determine which is the more accurate?

The reason for me asking is the 'efficiency' tab and associated graph say 5.49 If this relates to a COP then i will be over the moon. I dont yet have any other monitoring installed and have been trying to decide which way to go.

The graphing statistics that i can get out of the 'my vaillant connect' gateway app are not very sophisticated. But they do appear to show some interesting results so far. For those of you that have a Vaillant Arotherm, do you make use of the data and over a longer period do you find the data accurate enough to be of benefit?

Pretty quick to install or the download? Ordered and collected the antenna from Currys, tried it out on the floor before i committed to drilling a hole in my house wall. Test all good. So mounted in on the side of the chimney, aligned it easily and have been good to go all weekend. Easy peasy. Had a text over the weekend from Openreach saying they will arrive tomorrow Tuesday to install my broadband. I took great delight in telling them that their incompetence and attitude were incompatible with me paying them any money so please dont bother.

Starlink is live. Only lying on the garden floor and partly obscured by hazel trees in this temporary location but 324meg download and 31 upload. Not too shabby

Well i bought a starlink standard this afternoon. Once i have it installed i will report back here and then tell BT to do one.
