 Poor Cold Water Flow?For more information click here
GAH Coldstream The Coldstream System The Coldstream systems by GAH Heating Products have been developed as an advanced solution for domestic hot and cold water installations. A Coldstream system will increase the water volume and maintain the mains pressure to both the hot and cold supplies, even when more than one outlet is in use at the same time. Coldstream has been designed to function on the minimum standard for domestic water supply as provided by local water authorities - which is 1 Bar at 9 litres per minute at boundary. Coldstream Accumulators can also be utilised to increase the flow rates to unvented cylinders, combination boilers, heat exchangers, electric showers and other mains fed applications. GAH offer full technical assistance and design service to enable the optimum Coldstream system to be configured to overcome situations where poor mains supply and pressure are considered a problem.
How the Coldstream System Works The system mainly comprises an Accumulator (cold water storage vessel). The Accumulator has an internal controlled butyl diaphragm, incoming cold water is stored within this diaphragm at mains pressure. The air space between the diaphragm and the Accumulator case is pressurised, this balances the supply and maintains pressure to an unvented cylinder or mains pressure appliance and cold outlets. When hot and cold water outlets are turned on, the stored water from the Accumulator supplements water from the incoming mains, this results in consistent pressure and flow to all taps, showers and baths even when outlets are used simultaneously. Pressure will be sustained as long as the Accumulator is of adequate size and is holding sufficient volume of water More than one Accumulator can be linked together to satisfy greater demand. |
