Sentinel X400 System Restorer 1Ltr is rated 4.7 out of 5 by 49.
Rated 5 out of 5 by from Easy and safe Had to clean a central heating system before adding new replacement rads. The whole process was very easy and simple and the amount of sludge visible in the power flusher was unbelievable. After flushing the system there was an amazing increase in the overall heat in all the existing rads.

Rated 5 out of 5 by from Great cleaner I bought this as my boiler had started making banging noises (kettling). I introduced this to the system via the towel radiator (as advised by the Sentinel technical helpline) and literally within minutes the boiler was running much more quietly and the radiators are piping hot. Going to leave it in the system for a week then drain and dose with inhibitor. I can thoroughly recommend this product as it certainly exceeded my expectations.

Rated 5 out of 5 by from It worked I had some troubling noises coming from the pipes leading into my radiators. After bleeding them, this got no better. I don't remember my heating system ever being cleaned and we've had it for over 15years. I didn't really have the money for a powerflush, so I decided to give this a try. We have a sealed combi system, so I turned off the boiler and figured out how to drain the whole system. Thankfully I have a bleed valve directly outside my boiler, so I opened it and opened the upstairs radiator valves and finally the downstairs one to let the air out and allow all the water to flow out of the outside drain valve. (If you don't have a drain valve near your boiler, you might have a radiator with a drain valve at the bottom, you can attach a hose to it with a jubilee clip and drain it that way) Then, I isolated the radiator closest to the boiler and poured in the whole bottle of x400 with a fill kit after removing one of the radiator valves. Refilled and turned the heating on to let the x400 circulate, bleeding the radiators to remove trapped air. It's been less than 24 hours but already the worrying sounds from the pipes has seemed to go down and radiators which were previously lukewarm at best are now much hotter. I'm going to leave the x400 in the system for a few more days before draining and flushing with fresh water. *Remember to top up the system with a suitable inhibitor after you've flushed the x400 out.

Rated 5 out of 5 by from Restoring old central heating Using it in an old central heating system which has not been cleaned in decades. Will leave in the system for 4 weeks. May be my imagination, but after a couple of days, already there seems to be an improvement in some of the radiator cold spots.

Rated 5 out of 5 by from So good I used it again Second time using this first was several years ago. It worked well then. I have come up against a rather stubborn blockage in very old system and put the two bottles in an empty system. Topped up with water. Early days yet but previous cold spots are showing signs of warmth after only two days. Will keep my fingers crossed
