Hi all,
my radiators work fine but every 6 months or so my water starts running cold (Halstead Ace High Gas combi). I get the heat exchanger changed and it's great again for another 6 months. When I drain the radiators the water that comes out is a little dark but not sludgy as such but there is visible black particles in the heat exchangers that are taken out. Incidentally, the system is always filled with inhibitor and a few years ago I got the system flushed but it didn't seem the have any lasting effect; there is a magnetic filter too.
My question is, what is causing this?, is one of the radiators disintegrating some how?, if so how can I ascertain which one?, I've considered getting a new boiler but am concerned that the problem may still be there and that will clog up too.
Any advice would be much appreciated.
Thanks.
