OSO SuperStream - OSI

  - for exceptional flow rate performance

The SuperStream system provides boosted performance for poor mains supply. Guaranteed good flow rates for multi-outlet demand, with very low maintenance. Pre-plumbed package for easy installation, with proven performance over 20 years.

The OSO SuperStream is a unique concept that takes the performance of an unvented cylinder to another level. Traditional unvented cylinders are dependent upon incoming mains pressure and flow rate to produce the high flow rates associated with the product. SuperStream dramatically boosts the flow rate available to the hot and cold water taps by supplementing the mains flow rate with stored water in an accumulator.

The accumulator stores water in a butyl membrane and then delivers it to the cylinder and the cold water pipework when demand exceeds the mains flow rate available.

 

SuperStream is typically used in large properties with multiple outlets or in properties where mains flow rate is poor. The system offers performance unrivalled by any other water heating system. High flow rates to multiple outlets can guaranteed even with an incoming mains flow rate as low as 5 litres per minute.

Key advantages:

  • Boosts performance for poor mains supply.
  • Pre-plumbed package for reduced fitting time.
  • Proven performance over 20 years.
