Tried other cheaper central heating system cleaning liquids but sentinal x800 is the best
Its easy to apply the solution to the system, so far so good for the
Used this before it works really well at lifting and suspending the sludge in as little as 1 hour. Works most efficientley when heat is introduced via the boiler or an external source.
it can be left in the system up to 20 hours but if left longer will start to loose its properties to keep the sludge suspended allowing it to resettle.
Used sentinel x800 several time's to keep my Central heating healthy. Works very fast but recommend leave in the system for few more hours (3-5h in recirculation). Cleaning my system every second year and addind sentinel inhibitor x100 every year.
Made a massive difference. But 2 of my Rads were to bad even for this.
I cleaned my magnetic filter out and refilled it with this product. Ran the heating as normal for a full day and drained the system. The water was really dirty and my magnetic had collected a lot more. It isn't a "A will fix everything" product but definitely made a difference.
Good value and perfect for cleaning central heating system.
great product the best for cleaning central heating systems
Dissolved a very sludgy central heating system flushed out after a couple hours of use. Heating running a lot quieter and hopefully rectified a “kettling” issues great service from my local Toolstation and cheapest locally.
Keeps the system in good shape for the winter. I use this then empty the system and refill with Sentinel inhibitor.
Helped to clean a lot of the sludge from my radiators, plumber said keep putting heating on in the summer now and again to stop sludge building up and blocking some of my radiators.
Drained the system till almost clear, flushed it through and applied the cleaner. That was when the weather was cooler. Report back was that the radiators were working more efficiently.
Needed to clean my central heating system to ensure that working most efficiently. Used as recommended and flush system well.
Great product simple to use just what I wanted system flushed inhibitor added and heating tested - another success.
All good worked welll.Cleaned out system properly. Had dark dirty water coming out for a long time
Does the job anyone can protect their heating system without the need of a heating engineer
Good quality cleaner for wet central heating systems.
Easily ordered, quickly organised and easily added
Did the job nicely. Pre winter system flush. Used 2L over 4 hours then flush and drain system 3 times.
Mag filter needed several cleaning cycles to remove gunk. Worked really well. Pretty impressed. Next added X100 x2 then rebalance rads.
It certainly cleared out a load of fine sludge which took several freshwater flushes before the water ran clean. No big lumps to be seen so X800 seems to break down the deposits.
Tried one cleaner, in for a month, no real changes. Did a drain down, found a dribbling pipe. In 2 hours of running at high heat, debris on the magnaclean, dribbling drain down pipe was flowing. Confident that the system should work better now. Better than other treatments.
