When the mains water flow and/or pressure is low, the water performance from showers, taps and other outlets in the home is disappointing, and multiple outlets can't be used at the same time. The AccuBoost range of accumulator vessels provide a solution by providing additional water flow to improve water performance and allow multiple outlets to be used simultaneously.
Suitable for systems more than 2.0 Bar natural pressure, the AccuBoost 330L accumulator vessel will boost the water flow to an unvented system to deliver up to 24 litres per minute for 7 minutes.

AccuBoost accumulator vessels store mains cold water around a bladder filled with pressurised air. The air is compressed as water is enters the vessel, so when an outlet, such as a shower or tap, is opened, water is forced out of the vessel by the air in the compressed bladder.

• Supplies an additional 24 L/min to the incoming mains flow for up to 7 minutes
• Suitable for unvented cylinders
• Lightweight, composite material
• Link multiple tanks together for additional capacity
• A 'water-on-bag' design reduces strain on the bladder, preventing damage caused by excessive pressure
• Supplied as one unit ready to install
