Cleans and protects underfloor heating systems. Sentinel X700 is a solution containing a stabilised biocide for use in underfloor heating systems. The lower temperature in such systems promotes the growth of bacteria and fungi which can cause problems such as blockages of the pipe work, manifolds, valves and heat exchangers. Microbiological growth can also produce unpleasant smells and cause corrosion of the heat exchanger or manifolds. This can severely disrupt the smooth and efficient operation of the system. Sentinel X700 is specifically designed to eliminate these problems in underfloor heating systems
