Rated 5 out of 5 by Best boiler cleaner A very good quality cleaner, fast acting - does what it says on the tin 29 Feb 2016
Rated 5 out of 5 by Brilliant product This stuff has just saved me £100's. When my heating engineer found a blocked pipe in my boiler which would require the boiler to be removed from the wall, I was facing a large repair bill. I've never been a believer in "Liquid Engineering" but for £20 I thought it worth a try. Left it in the system for 5 days then drained and flushed. Boiler working fine now with stable pressure. Now installed Sentinel 100 inhibitor. Delighted! 13 Jan 2016

Limescale removal?

Will this also act as a boiler descaler? So no need to additionally dose with X200 descaler?

Answer: 
Hi there, the prime function of Sentinel X800 is to clean corrosion debris from a dirty central heating system and not to specifically descale a boiler. It will have some effect but if the problem is boiler noise then Sentinel X200 is the best product to prevent boiler noise.
Kind regards

Answer: 
Hi there, a 1 litre bottle of Sentinel X800 Jetflo is sufficient to clean a typical system of approximately 8 to 10 radiator panels. For larger systems 2 litres of product should be used. Where systems are badly fouled, a higher concentration is recommended, i.e. 2 litres of Sentinel X800 Jetflo in a typical system, though the product will not clear a completely blocked pipe.
Kind regards
