Thanks guys. Yes Im going to accept my heating system as is - I dont use it often enough to warrant any investment. Its seems to be working ok according to everyones feedback. My neighbours have been told theres is at risk of overheating by an engineer so really asking for recommendations for someone to look at their system. Doesnt seem to be that many specialists around. And the ones I have called dont seem very trust worthy.

Im looking for underfloor heating engineer recommendations to check my system is performing optimally and my neighbours are looking for the same please. My system works - takes about 3 hours for heat to come through though - wondering if its been set up properly or this is normal. I cant find that many specialists online - I called a couple of places One based up north want £450 for an inspection - includes thermal imaging Another place in London - £130 + VAT - showed them photos of my manifold etc - theyre saying its an "old design" and recommend a complete replacement - quoting £2500

Thanks Temp. Just had the system on for 2hours+. Manifold pipes are hotter now - including ones entering floor. And heat is starting to come through the amtico. Floor temp is below luke warm to the touch still. Maybe as Im ground floor Im looking for 3 hours plus to get to full temperature? Is it worth a thermal imaging survey do you think? https://www.red-current.com/thermal-imaging-surveys/under-floor-heating

Thanks for all the amazing feedback everyone! More images below. Status after having heating on continuous for 30mins 1) Its a pressure gauge not temp gauge showing just over 3 bar? 2) Engineer took off the white device - is that motorised mixing valve? He tried to depress the metal pin down with head of screwdriver even with significant force he struggled to depress the pin so he struggled to see how the white device would have the power to depress it - does that make sense? 3) The pipe work to the left of the ESBE device is red hot to the touch - everything to the right of ESBE device is somewhere between cold and luke warm - barely any heat at all in any of the pipes - including those entering the ground. Had heating on circa 10 hours - floor was warm after that time. All thermostats are set to 27 degrees + and room temp was nowhere near that. 4) Is the pump running, can you hear it or are there any lights on it? No lights on it but I can hear it running I think 5) What is the temperature dial, the big white knob top left that says "upnor" set to? It has no temperature on it. See comments on pics. Its looks like it some kind of on/off mechanism? Theres a red indicator inside it by the looks - should that be in down position? 6) What are the pipes embedded in, underneath the amtico? Dont know. I am on ground floor. Theres multiple low rise blocks being serviced by central source circa 500 metres from me. Feedback from resident on non ground floor in another block is his takes 2 hours+ to get warm. Another guy in my block - not ground floor - where engineers just visited - reported same issues - of different design - have quoted him £250 parts and £250 labour for fixes. Engineer admitted to me he is a generic electrician and not an underfloor expert. Can anyone recommend an underfloor expert in London area please? 7) Im awaiting photos from my neighbours in our block. It looks like our entire block is different make to other blocks. Im 8 years in to 10 years of NHBC warranty. Doubt they will do anything as its broadly "working"?

Hi all. First time poster I live in a new build development of flats that has a communal heating system. Hot water is generated centrally - then pumped to us. That hot water then heats cold water in an indirect hot water cylinder setup. We have underfloor heating powered by the centrally heated water too. We've just had engineers visit each flat individually to powerflush debris that was supposedly in the pipework. From day 1 my underfloor heating always seemed slow to warm up and patchy. But assumed that was normal - heard it can take 2 to 5 hours to heat. The flooring is Amtico I got one of the engineers to look at the UF manifold area. See picture without flow restrictors Hes saying my setup is different from other flats in the development. They look like picture with flow restrictors He states I have; 1) Missing flow restrictors 2) No control board/PCB for motorised mixer 3) No temperature sensor for underfloor (so no way to set temp of floor) Can you tell from the photos if he is correct? And what the impact would be of leaving. They are about to send me a quote for various replacement parts. The floor does get warm eventually but takes 2 hours +
