OSO Dualstream Water Heating System

The OSO Dualstream is a unique concept that takes the performance of an unvented cylinder to another level. Traditional unvented cylinders are dependent upon the incoming mains pressure and flow rate to produce the high flow rates associated with the product. The Oso Dualstream 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.

Concept: The OSO Dualstream is a patented package the contains an OSO 20 series unvented cylinder and a cold water accumulator. The accumulator stores water in a butyl membrane and then delivers the water to the cylinder and the cold water pipework when demand exceeds the mains flow rate available.

The OSO cylinder is supplied as a fully flooded cylinder with the accumulator acting as an expansion vessel in addition to boosting the flow rate to the taps.

Performance: The OSO Dualstream will give 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.
