weve actually not used any of it, ive never liked the idea of it, the cost of it compered to copper wanst that much of a saving and by the time you added a magnaclean, suitable inhibitors etc, it was cheaper to use copper. But we do look after 9 biomass boilers that have all been piped up with LCS by another installer so i will have to make my boss and the clients aware that we may need to carry out sample tests at service.
cheers for this info Shaun
