Hi all,
We recently spent 3.5k getting our single pipe gravity fed system "converted" to a twin pipe pressured system with combi boiler.
90% of the piping downstairs was replaced, but for some reason they didnt touch the upstaires piping... but they all work fine upstairs so this isnt the issue for now.
Basically what you are looking at is the radiator in our kitchen (was replaced with a new one at time of install). Now what you can see is the two pipes comming through the wall are the flow and return feeds (flow to the left, return to the right (yes from the layout from the rest of them they put the thermo rad valve at the wrong end but im assured this isnt a problem). Now as you will see, the pipes come out of the wall and go into the kitchen rad, but also are supposed to feed another rad in our dining room about 3m away where the piping is run under the ground.
Now the rad in our dining room has never worked, but we always put this down to the way it was piped with a gravity fed system. So with this install based on the installers recomendation, we have replaced the rad, got new valves at both ends (thermo and normal), and replaced the visible pipe.
This rad STILL doesnt work though! I've tried everything from shutting down all the rads on the system to try to force the heat to go to it, to bringing up the floorboards at the half way point, disconnecting the pipes, and try to investiage where a blockage can be. Now from my investigations we have discovered the blockage or circulation problem is on the flow. I have been able to check that from the dining room rad back half way is clear, but as the joins in the kitchen I am unable to try to flush this through.
So now this problem is, the installer is saying he will either replace the compleate pipework for £300, powerflush that section for £150, or the whole system for £300 inc chemicals. Now the problem is I dont want to pay for something that isnt needed, so the dilemma I have is we could pay to get the pipework to be replaced, but as far as Im concerned this should have been done in the first place, especially as we made them aware that rad has never worked and clearly the pipework wasnt flushed despite a new rad etc being installed. Or pay for the the pipes to be flushed, only to find that it is infact a circulation problem.
So now I dont know what to do! To me, this looks like one radiator spur, feeding another one, as when I shut the kitchen rad main valve off (not the thermo) the whole pipe goes cold rather than just the part leading to the kitchen rad.
Sorry for the essay but the guys saying hel come round tuesday as hes got some other ods and ends to complete, so I need to be able to let him know what I want done!
Any advice greatly apreciated!!
