Sentinel X100 Central Heating Scale Inhibitor 1Ltr (79683)

Hi there, Sentinel X100 is dosed at 1% of the system volume ie 1L per 100L or approx. 8-10 standard sized single panel radiators. Kind regards Sentinel Customer Service

Hello Andres - We do not believe that X100 would have any beneficial effect in terms of noise reduction or heat retention. But it is advisable that water treatment added takes account of thermal store capacity to ensure the whole system is adequately dosed. Kind Regards, Sentinel Customer Services

Hello - We sell our Sentinel X100 Inhibitor and have done so for years. I am not sure what you are referring to when you state "No Nonsense Central Heating Inhibitor"? If it is not a Sentinel product, we would recommend that you drain and flush your system before dosing with our products. Kind Regards, Sentinel Customer Service

Hi there, X100 is required to prevent corrosion in the central heating system whether a magnetic filter is installed or not. Kind regards Customer Service

Hello Paul, X100 will not stop this problem. However, it will help should be problem be solved by cleaning the system and then by adding X100 Inhibitor when refilling, to protect against limescale build up. The product required would be X200, which is formulated to treat a thin layer of scale build up of deposit on a heat exchanger in the boiler. We recommend adding X200 to see if this helps the problem (certainly with boilers). If the radiator continues to make noise, this could be a trapped air or parts issue. A chemical clean, using Sentinel X400 or X800 (depending on the timeframe for cleaning) may also help the situation. Kind regards, Sentinel Customer Services
