Replenishing the internal expansion in unvented water heaters

15 August 2023

As pioneers in stainless steel unvented cylinders since 1960 Fabdec continue to innovate in this field.


Our EXCELSIOR Venturi technology replenishes and protects the internal expansion of the vessel, thus prolonging its service life.

As cold water is drawn through the Venturi device air is infused into the supply, which then settles above the heated water, thus replenishing the air gap.

Heat pump and solar compatible, the system ensures a long life with no moving parts or external expansion vessel. It is WRAS and UKCA approved, designed and manufactured in the UK. We offer direct and indirect models up to 500 litres with market-leading warranty.
