Great success as Borat would say !!!
I have used X800 sludge remover with great success. Our boiler (Worcester Bosch 40cdi Combi boiler) had a problem with heating working fine but hot water being luke warm and going cold. I spoke to the guys at sentinel and they suggested X800 which is usually used with powerflushing machines. I added it in and ran the bath a few times over 2 days. Its cleared the sludge that was probably in the plate heat exchanger and now the water is lovely and hot again. I have a magnaclean which picked up a lot of crap that the x800 stirred up. I've flushed it out and added X100.
By the way its ok to use X800 with aluminum plate heat exchangers for as long as you want according to Sentinel.
