He canceled today, coming tomorrow at 9.
I found an arrow, it’s pointing downwards. The pipe, sorry, is it the one on the picture? It’s going down parallel water cylinder, but I can’t see where it’s connected.
Actually it’s the newer one to the left of where you’re pointing, but does look like it’s connected to the cylinder. Have you tried to range rate the heating or are you waiting for your plumber to do it?

Oh sorry, white one is a condensation pipe, he installed it going into the bathroom wall and under the bath, there’s a water connection there, he added this tube to that connection.

Sorry,I didn’t mean the plastic one, I meant the copper one (as now shown in edited photo). As I said, I think it’s connected to the cylinder

Did you try adjusting the heat output?
No, Im honestly straggling to understand any of this, I don’t want to press something and make it worse. If he can’t fix it tomorrow, I will look for someone else as I find it very strange now that he hasn’t checked on any of the issues you all mentioned and it’s been over 20days since installation.

It wouldn’t make it worse, it would either fault again or help with the issue, but might as well leave it to him tomorrow though if you’re not comfortable.

I’m not sure if I can help explain it any better, but the boiler flow and return temperature are too far apart, which suggests several issues which have been mentioned.
 
Any joy @IrinaPri or was it another no-show?
Thankfully he came, he started with cold system, changed boiler to 12kw, amended pump setting as per above, set over run on a pump to 5min. All radiators were open, the boiler did not go to high flame straight away and no fault 23 came on after turning on the boiler, after 45min all radiators were hot and only then boiler went to high flame and then stayed at around 71C. I’m keeping heating on for the weekend, but on Monday will see if everything works - I will set Hive to 20 (it’s 23 now) and hopefully boiler will fire up and stay on to circulate and maintain the target temperature. Thank you again for your advice, I will update on monday hopefully with good news! Have a good weekend l!
 
Update - You guys are most amazing professionals- the boiler stayed ON 🥹 Thank you all so very much, I’m so glad I decided to seek help here and it’s obvious now that my guy unfortunately does not have enough experience otherwise he would have try all this weeks ago.
At the moment temp on boiler 75C and holding, I set hive to 23C an hour before coming home and radiators all hot now and Hive temperature rising. The pump however still makes noise (video hopefully will upload below) not constant but often. I will keep an eye on it. A2615798-7961-4092-AB8C-3B18B12D06DD.jpeg
Again Thank you All for being so kind!!
 
Can I please check- I need to press white Arrow once til it has 2 orange lights and says II ? Do I need to turn anything off or just press it while pump and boiler on?
Thank you,
Irina
Yes press the button until there are 2 lights on, don’t think you can do it without the pump running, so yes leave everything on with a demand.
