Post and beam

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.

The thing is i have had this service at my rental for the past 16 months while we built this house. It really isn't worth it. The BT TV offering is not good.

No. Openreach are unavailable to speak to. So they did not appreciate that they needed to cut some trees to get a line of site for an overhead cable run. The first engineer that discovered this did not leave any notes for a subsequent engineer. so the issue was repeated when he arrived. In between this there were 2 cancellations of my service altogether from my previous address because they cannot seem to arrange a home move correctly. On Tuesday last they just failed to turn up all day with no communication to me of any kind. They have lied about offering me dates for another visit. apparently waiting now for 3rd party permission to cut the trees. If they dont have this permission i dont see how they could offer me a new date. further proof that they lied to me. I am done with the incompetent idiots.

I am so p1ssed off with BT/Openreach after 4 failed attempts to actually provide service at our new build. I give up and am thinking of a Starlink service. 4G/5G in this village is non existent. Does anyone have any first hand experience of Starlink. Tried the app yesterday and got a prediction of occasional dropouts due to 4.6% obstructions. But the direction of these obstructions is to the south. The mount would be on the north wall with the house behind me so no surprise the signal would not be good from behind.

I have a pair of these spare if anyone wants them. Free to a good home but buyer collects

I self installed my brink ducting. 200 sq metre 2 storey, with 90mm green ribbed semi rigid. Agree that it is a lot of work.Although its only semi rigid it gets to feel pretty rigid when trying to manipulate it through joists etc. I have 15 runs in total. I had to get a little creative with the routes up through to the loft from the ground floor. To the extent that even the Potton quality manager said, 'thats a good idea'. It goes together easily and very securely by the way as has been said already.

Exactly, and thank you. As per the above observation from @SimonD , i did indeed have many conversations with the installer,( and others that i rejected because of their responses). The entire point of this story is that i have not had what i have actually already paid for. Now, i take on board all the advice about tuning and optimising what i have. i am truly grateful and it might be that this gets me to where i have a balanced upstairs and downstairs. As an aside, i realised today that if i am operating in pure WC mode then the Hallway mounted room 'stat that i stressed so much about moving is in fact not relevant to my temperatures.

40c if i remember correctly. I always wanted no more than 35 if possible. Downstairs UFH is operating at below 30 currently

No they are not at the target temperature. And because i dont have seperate temperature control upstairs i wonder how it could be otherwise. Not withstanding that the radiators are the sizes specified by installer.

I only really mentioned the Delta T figure because the discussion usually mentions a 7 degree Delta T when the topic comes up.

No. Apologies, appear to have missed responding to that.

So if i installed a mixer and ran the radiators at a slightly higher temperature. How would the UFH behave? bearing in mind the gentle .4 WC curve remains (perhaps not) #A: down mix temperature to some value and run for as long as ... well how long actually? #B: Run at the same temperature as the radiators but for a short period. Currently the Delta T is 3 degrees so the down mix would be minimal would it not.

Yes its the 720/3 senso comfort and its on 'active' if i remember correctly. Rads are K2 at the sizes specified. I dont believe these are the issue. Not an expert and happy to be proved wrong but they have no option to be controlled seperately and that is what i asked for and is in my unqualified opinion the issue.

Room stat is wired and downstairs, my choice to have it hardwired, possibly not one of my finest. The UFH actually heats the ground floor very well and therefore does indeed switch off at desired temp. As previously mentioned. The manifold temps this morning at 7 when it was heating were 25c flow & 22c return. ( analogue gauges on the pipework) The 35c i mentioned was the highest i hoped it would need to run at for efficiency sake and not a set temp. It looks like it does not even need to run that high yet. For info the WC curve is .4

Vaillant Arotherm 5kw. 2 months old. one week since moving in.

Thanks Nick. I think i have enough space to install a TMV to the 22mm pipe pairs. As an aside my flow & return temps gauges show 25c and 22c, so a Delta T of just 3 degrees. Still waiting to hear from my installer. I am about to become mister angry customer.

Hi @Nick ? Can i recover this to an acceptable solution without major surgery?

Exactly. Hence my question to my installer. I dont believe they have delivered what i asked for. As it happens, and totally unsolicited the MCS guys have asked if they can audit my install.

The yellow vertical pipes come from the Ashp up through the slab and go left and up to the UVC. They are 28mm. On the manifold picture the 2 pipes come from the UVC area upstairs, they are 22mm. No TMV .

Will do once i get home
