Hot water temperature
Maximum temperature 65°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 effects of scale in hard water
areas.
Temperature control
To obtain the maximum performance, this unit
should be installed, operated and maintained as
instructed in this book. The full performance
specification as below for the unit is achieved
with a blend set between 35°C – 40°C and
supplies of 15°C cold and 65°C hot with
nominally equal pressures.
1) The blended water temperature is
maintained within 2°C with a 10°C change in
the hot and cold water supply.
2) The sensor effects a shut down to seepage in
about 2 seconds if the cold supply fails.
3) Shut down to seepage is achieved even if the
hot supply is only 12°C above the blend
temperature.
4) The blended water temperature is
maintained within 1°C when the pressure
between inlet and outlet is halved (defined as
a pressure loss ratio of 2:1) on either the hot
or cold side.
Maximum static inlet pressures
1 bar or 10m (supplies must be gravity fed at
nominally equal pressures).
Minimum static inlet pressure
0.0075 bar or 75mm (required to prime the
integral centrifugal pump).
