Sentinel X800 Ultimate Cleaner 1Ltr
Really good cleaner
I regularly use X800 for heating and chilled water systems and it does the job well.
Screwfix have this on a promotional price at the moment and its a really good price.
Would recommend this product highly.

Central heating cleaner
due to the problems that i was having with my CH system i thought i'd give this product a go. firstly i flushed my system through before adding this product , i then waited 7 days as instructed before flushing the system to clean. It seems to have worked as intended. The radiators are now heating up as intended. Very impressed with the product.

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.
