The value of solar heating depends on the continued efficiency of heat transfer between the solar collector and the thermal store.
Sentinel R100 is formulated for solar heating systems operating up to 200C, containing special reversibly vapourisable inhibitors to protect all metals commonly found in solar heating systems, whether your system is operating at its highest or lowest temperatures you can be sure your system metals are afforded superior protection against corrosion, fouling and deposit formation. Sentinel R100, a clear blue liquid, is easy to use and effective straight from the container. It can be used with the Sentinel SolarFlush unit for easy filling of systems.
