Hi there,
I need please some advice with our heating system...
We moved in a house this summer and we are having issues with cold radiators. The CH piping is 10mm plastic and some of the neighbours say that the pipes fitted are not the correct ones and that is why they get blocked. The houses were built some 22 years old and we have 21 radiators (5 on the third floor, 8 in the second floor and 8 in the first floor) and the boiler is in the second floor.
So my first question is, can the pipes fitted be "the wrong type"? Or is this a common problem taking into account the age of the house? One of the neighbours decided to change all pipes to 15mm but it cost them a fortune and the hassle was huge so I was wondering if there is a way of avoiding that, which leads to my second point... I need some advice to be able to unblock the pipes...
When we moved in this summer I decorated most of the rooms and flushed all the radiators. A lot of sludge came out of them. This winter we had issues with a couple of the radiators and I had a plumber come and try unblock them with a wet vacuum cleaner. It worked for some but others got blocked again so I decided to use Sentinel X400 for 4 weeks and then drain/flush the system. I managed to unblock the radiators that were cold (flushing them with the mains water valve together with the CH pump) but now I we have other radiators going cold.
I want to use Sentinel again (X800 for the sake of time) and try to flush the sytem but I would like to try and ublock the pipes in the first place. I have seen videos and read about using 12V air compressors to unblock pipes. I have one for the car tyres but I have no idea how to connect it to the pipes?
Thanks for the comments...
