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.
AccuBoost accumulators with a pump will draw the legally allowed limit of 12 litres per minute from the mains supply, in addition to the extra flow provided by the vessel. This model can deliver up to 24 L/min from the vessel and a further legally allowed limit of 12 L/min from the mains by using a pump to offer up to 36 L/min for 7 minutes.
Suitable for systems with less than 2.0 Bar natural pressure, the pumped AccuBoost 330L accumulator will boost the water flow to an unvented system to deliver up to 36 litres per minute for 7 minutes.

• Boost multiple outlets, across multiple floors, all at the same time
• Delivers up to 80L/min and 3.0 bar pressure
• Very quiet operation
• Easy to install
• Suitable for mains fed systems
