Operating Parameters: Pressures And Flow Rates
Pressures
For optimum performance, maintained supply pressures should be nominally
equal.
Maximum Pressure Loss Ratio: 5:1
Minimum Maintained Pressure (gravity system): 0.1 bar.
(0.1 bar = 1 metre from base of cold tank to outlet of shower fitting)
Maximum Maintained Pressure: 6.0 bar
Minimum Maintained Pressure (gas water heater): 1.0 bar.
Maximum Static Pressure: 10 bar.

Flow Rates

Temperature Control
Minimum temperature differential between hot and outlet temperature: 10°C
Optimum temperature control range: 35 - 45°C
Maximum hot water temperature: 85°C (BS 6700 recommends that the temperature
of stored water should never exceed 65 °C. A stored water temperature of 60 °C is
considered sufficient to meet all normal requirements and will minimise the
deposition of scale in hard water areas).
