Superstream Accumulator System

Boosted performance for poor mains supplies.

Superstream uses patented accumulator technology to deliver powerful, consistent pressure and high flow rates — even when incoming mains performance is low. Unlike traditional unvented cylinders that rely solely on mains pressure, Superstream stores cold water within a durable virgin butyl diaphragm, ensuring enhanced performance to both hot and cold outlets during peak demand.

Ideal for large homes and commercial properties with multiple outlets.

Key Features

• Boosts performance where mains pressure is poor
