    PROBLEM SOLVED.

    Because four heating engineers failed to keep appointments, I was looking at replacing the Boiler... With considerable difficulty I decided to remove all seven radiators, pressure clean them and reinstal. Refilled with X800 and within an hour, vast improvement in DHW Heat Level. It shot up from 29c to 55C and has remained there. Looks like the problem solved. Will drain and refill with Inhibitor. Save money folks... read the guff then flush with the appropriate fluid.

    Sentinel X800 Fiasco

    Not used X800 before so not sure what is should look like, but pretty sure it should not look like that pictured. A mixture of coffee grounds and gelatinous oily lumps with the whiff of creosote. Not allowing this anywhere near my central heating system and not worth hassle of returning this gloop. Minus stars, avoid at all costs!

    SENTINEL X800 FAST ACTING CLEANER WORKS LIKE MAGIC,; CENTRAL HEATING BEST FRIEND.

    Followed instructions, DRAINED WATER OUT OF THE BATHROOM RADIATOR AND TOPPED IT UP WITH Central Heating Cleaner Sentinel X800 Fast Acting, WHEN THE TIME CAME TO DRAIN THE SYSTEM THE WATER WAS BLACK LIKE OIL THAT WAS IMPRESSIVE, REFILLED THE SYSTEM WITH CLEAN WATER PLUS OCCASIONAL AIR RELEASE AND TOPPING UP AGAIN WITH WATER THE RADIATORS NOW QUICKLY HEAT UP. i WILL CERTAINTY USE Cleaner Sentinel X800 NEXT YEAR TO KEEP THE SYSTEM 100% in good order. GREAT PRODUCT.

    it does what it says on the tin

    Recommended by reputable local heating engineer that I have used over many years. The product works as described and have used it in the past number of years during my Central heating pre annual winter check and drain service. S Taylor

    best cleaning product less time

    Fast clean it cleans the system when its cold no need to turn heating on, in case if you leave heating on will work fast. if system not cleaned for many years will require second dose, do not leave in system for longer than 24hrs. better than power flush

    Great product.

    It has transformed my heating system for the winter. It works very quickly on removing the results of years of corrosion caused by the cast iron boiler that we had.
