Hi,
I need bit of an advice about finding the filling loop in my heating system. Apologies for long description but thought to cover as much so relevant solutions can be suggested. I have spent endless hours searching internet including this forum and everywhere it is mentioned there must be two valves either near boiler or cylinder which is used to repressurize heating after draining and refilling but there isn't any installed at all near existing Megaflow unvented indirect cylinder by Heatrae Sadia or Glow worm Flexicom 30HX system.
Symptoms: -
My radiators were not getting hot enough after running heating for long time and called engineer who just bleeded few radiators and increased the pressure of heating system (which he found after a struggle as he said but I didn't see). He charged me £200 for 30 minutes job which is rip off.
Now within 2 weeks time, I got another plumber to change the radiator and two TRVs for which he had to drain whole heating system. He refilled the system by just turning the cold water supply only as there's no filling loop and pressure meter anywhere in the system to see what's happening. All radiators were bleeded twice and now no more air in any radiators.
When we turned the boiler on, it showed Fault 22 (i.e. low pressure error). We had to reset it twice before error disappeared automatically and heating started working but few radiators were not getting hot at all. Radiators were tested for air again it is fully filled with water as only cold water was coming out. Plumber advised to close some of the TRVs and locksheild which will push the water to other radiators, which did the trick indeed but except two radiators.
Problem: -
Out of 15 radiators, 2 of them are not getting hot at all and I am worried it is down to the water pressure in heating.
Help needed: -
Please if looking at the picture of cylinder, someone could advice if they notice anything which can be used to repressurize heating system. I know all the valves except red valve and the connection line it is attached to. Not sure if this can do any trick.
I have checked the Glow worm Flexicom 30hx system and there are no valves visible at all except one to switch off Gas supply and Megnaclean. I have not opened any face plate to check and won't do it at all as it is boiler system.
Thanks for your help and taking out time to read this.
