The use of Sentinel water treatment is internationally endorsed by all major boiler manufacturers to protect their products in both the domestic and commercial markets. This support for quality water treatment is evident in boiler installation and servicing manuals, where Sentinel products are consistently recommended by name.
In addition to our own rigorous testing regimes, the Original Equipment Manufacturers (OEMs) regularly conduct compatibility and performance tests to ensure that our products deliver the very best solutions, earning us our place in the aforementioned installation and servicing literature. By following this literature, the engineer can have confidence that they are delivering the best solutions to their customers.
Our relationship with the OEMs of the heating industry extends beyond our reputation for quality products. We work alongside them on joint technical, sales, marketing and research and development initiatives, to help all parties deliver the best products and services to heating engineers and, in turn, the householder or landlord. The training our Technical Support Managers deliver for these manufacturers, whether at their own training facilities or on site, has been voted the best in industry.
Our mutual merchant supply relationships ensure that in every branch, Sentinel products are available alongside the OEMs’ products, whether a boiler, solar thermal panel or heat pump.
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. As of 2021, Sentinel is owned by Aalberts N.V., and sits in the hydronic flow control cluster.
