About the Product

Accumulator vessel technology is widely recognised as an efficient and energy-saving alternative to traditional cold water storage and electrically powered booster systems.

Designed to support stable water pressure and optimise water distribution, accumulator vessel systems provide an effective solution across a wide range of domestic and commercial applications.

Applications range from residential properties with combination boilers and unvented cylinders serving multiple outlets, through to larger environments including care homes, sports facilities and other buildings with varying water demand requirements.

By reducing unnecessary pump operation and supporting more efficient water pressure management, accumulator systems can deliver improved performance, reduced energy consumption and long-term operational benefits.

GWS Accumulator Vessels Features

  • Green energy saving alternative to booster sets
  • Suitable for domestic and commercial applications
  • Recommended for mains pressure of 2 bar and above
  • Multiple vessels can be connected for higher capacity
  • Booster pump option for low pressure systems (up to 12 litres per min)

Benefits

  • Can be installed directly on the incoming mains supply - no additional storage tank is required
  • No electrical supply required / consumes no power
  • Minimal maintenance
  • Silent operation
  • WRAS approved product
  • 5 year 'no air loss' guarantee

The only consideration for installing an accumulator system rather than a standard booster set is the physical space required, especially if more than one vessel is required.
