2.6 Mains water supply
The performance of unvented cylinders depends on the available mains water pressure and the pipe size.
In order for the performance of the Flurocyl solar cylinder to be ideal, an appropriate cold water supply must be available. The measured static pressure must be at least 2.0 bar. A corresponding flow rate of at least 20 - 25 l/min should be available.
NOTE: The mains water pressure is reduced during periods of high water consumption.Make sure you take measurements during these periods.
Example: The available flow rate of mixed water at 40°C is 25 l/min (15 l/min hot water of 60°C from the solar cylinder mixed with 10 l/min cold water of 10°C) if the measured static cold mains water pressure is 2 bar.
The solar cylinder operates satisfactorily at a mains water pressure of below 2 bar, but at a reduced flow rate.The unvented solar cylinder should not be installed if the mains water pressure is below 1 bar.You can obtain information on alternative hot water supply systems from
To keep the friction losses at a minimum, a minimum diameter of 22mm is recommended for the cold water supply in the building, satisfactory performances can also be achieved with 15mm pipes however.
