Communal Heating System - radiator and water not hot

catflapuk

Hello,

I live in apartment with communal heating system and have heat interface unit in my flat. From one day to another all radiators are not getting as hot was they used to and I have noticed the same with the water. I am clueless as to what the problem could be. Is it the HIU or the communal system that may have a fault? How can I find out?

Thanks

Just touch the pipes that you have access to.
On one side it's hot, on the other side it's cold/lukewarm.


Typically, the boilers are locked up, for your safety, but mostly to stop people messing with it.


Berkeley Homes was supposed to refurbish the three boilers when they did the office conversion on the building I have a flat in. On handover, only one of the three boilers was working. OM Peverel, the management company Berkeley Homes appointed, colluded with them, so the snag list was never done. After the three year warranty period was, over, we kicked out OM Peverel, and found out too late. Loads of problems, not just the boilers. So, pray it's just a stuck valve.

Thank you pincher. I have just done what you said and you are right... one side is luke warm, the other side is cold. And yes, we do not have access to the communal boiler - are you suggesting there would be more than one boiler in the room? By stuck valve... do you also mean in the 'boiler room' or in my flat?

by the way, I meant I touched the pipes on the radiator on the left and right.

If other flats have plenty of heat, then you have stuck valves or clogged radiators.


I suppose the timer/programmer could be faulty, and shuts off an incoming valve.


If you call a plumber, it would help to have access to the distribution cupboard, which may contain a heat meter per flat.
I wouldn't be surprised if somebody was checking which pipe supplies which flat, and shut yours off, but forgot to open it again.
