Excelsior, a division of the Fabdec Group, offers bespoke stainless steel water heater cylinders that exemplify innovation and durability in hot water storage solutions. Manufactured in the UK, these cylinders are tailored to meet the specific requirements of both domestic and commercial applications. A standout feature of the Excelsior range is the patented 3S (Self-Sustaining System) Technology. This system eliminates the need for an external expansion vessel by utilizing the Venturi effect to automatically replenish the internal air gap as water is drawn from the mains. This design not only simplifies installation but also reduces maintenance requirements, offering a maintenance-free experience for users.
Constructed from high-grade duplex stainless steel, Excelsior cylinders are designed for longevity and resistance to corrosion. The cylinders are available in various capacities, ranging from 80 to 500 litres, and come in both direct and indirect models to accommodate different heating sources, including electric, gas, heat pump, and solar systems. Fabdec’s commitment to quality is evident in their manufacturing processes. The company has invested in advanced machinery, such as CNC Fiber Laser Welding Systems and high-capacity press brakes, to ensure precision and efficiency in production . Additionally, Fabdec’s adherence to EN.ISO 9001 standards underscores their dedication to quality assurance.
With a 25-year warranty on domestic cylinders, Excelsior provides customers with confidence in the product’s durability and performance . This warranty, combined with the innovative design and high-quality construction, makes Excelsior stainless steel water heater cylinders a reliable choice for those seeking efficient and long-lasting hot water solutions – Call our Sales Team today to talk about your requirements and how Excelsior can help!
