Blocked supply heating pipes? 2 cold radiators

Hi all,

I live in a second floor flat and have two radiators which are not heating up, and one which is only partially heating up. With the cold radiators, there is no heat in either of the supply/return pipes immediately underneath the radiator.

I've been trying to work out the configuration and this is what I have summised. I have a Potterton Performa 24 Eco HE boiler, in the kitchen. The heating supply comes out of there and into a cupboard in the middle of the flat, where there are connectors which split the large diamater copper pipe into 8 small diameter (plastic?) pipes. These pipes then run into the concrete screed and I presume they are separate supplies to each of the 7 radiators. What happens with #8 I have no idea! All of these pipes seem to be warm.

This has led me to suspect that the pipes leading to the living room radiators have a blockage, if the supply pipe was warm then I would assume it was in the radiator.

I have tried turning off the other radiators (bar two which don't have TRVs and I don't have the right spanner), and checked the pressure in the system (it needed topping up and is now about 1.5bar).

So my main question is, how do I resolve this block? I have no idea where the draining point is as none of my radiators have a drain point on them, and the lowest point is probably under the concrete screed. The heating pipes pass behind the sink, is it worth looking there?

If I need to put some cleaner or maintainer into the system, where do I put it and what should I be using?

Or is this a job for a pro?

Thanks in advance

Matthew

It sounds as if you would be better getting a pro.

If you want to start with DIY then a bucket test on each of the non working rads would give an indication of whats wrong.

See FAQ.
