Sentinel X800 Ultimate Cleaner 1Ltr
I live in a very hard water area and even though I have a good solution of inhibitor, I still get reduced water temperature every couple of years. This product cleans the system and the results are almost immediate. I leave it cleaning for a week, then flush the system and add inhibitor again. 5 years ago, I was advised that I needed a new heat exchanger in the boiler at the cost of over Â£200!! This product is much better value.

Great System Cleaner
I have used other cleaners but they don't work anything as well as the X800. Within 30 mins I could hear that this was working well and the system is now working like new.

Saved buying new boiler
Bought a tub of this to try in Sisters 25 year old boiler as it was making very noticeable kittling noises. Within a few days it had quietened boiler no end. Most impressed, esp as she was considering a new boiler and Â£18 was a lot cheaper than well over Â£1,000 !!
