Sentinel is a company with a clear goal: we offer water treatment products and services that provide the best lifetime protection for heating and hot water systems. Originally launched in the UK by Grace Dearborn in 1988 and subsequently a subsidiary of the leading multinational General Electric, Sentinel has operated independently since 2005, expanding its international reach and range of innovative solutions.
The story of our innovation is filled with firsts, from the pioneering of the practice of Jetflushing back in 1998 to the development of the world’s first multi-cyclone central heating filter , Eliminator, in 2012. Recognised as a UK market leader, we are justly proud of this reputation for innovation and new product development.
Our product offering has developed to address the needs of both domestic and commercial central heating installers and engineers, strengthening our range of products for traditional boiler systems, and expanding into products for renewable energy systems and potable water systems. We also have a number of products in our range developed specifically for specialised markets, such as Germany.
