Product Data Sheet

Safety Data Sheet

Boiler noise is an inconvenience for homeowners and can be an indicator of an underlying problem with the central heating system such as system design or mechanical faults. Once these have been ruled out as the cause of boiler noise the most common cause is a thin layer of limescale or other deposit inside the boiler. Sentinel X200 Noise Reducer is a highly successful treatment for curing the problem.

It is a non-acid, leave-in treatment; a gentler but still highly effective solution to this common problem. Treating boiler noise caused by deposits with Sentinel X200 Noise Reducer will also help to restore boiler efficiency.

1 litre of Sentinel X200 Noise Reducer is sufficient to treat a typical domestic system of up to 10 radiators. Larger systems should be dosed with twice this amount.

Open Systems: Dose via F&E cistern, via a by-pass feeder or use a Sentinel Dosing Vessel.

Sealed Systems: If the system is empty, add to any convenient point before filling. If full, use a Sentinel Dosing Vessel to inject via the filling loop or other access point.
