7.2 Recommendations before installing
Domestic hot water circuit design
Water pressure
The minimum working pressure to obtain the maximum domestic
fl ow is 0.8 bar.
The maximum working pressure of the domestic hot water circuit
is 10 bar. If the cold water supply pressure exceeds this, then a
pressure-reducing valve must be fi tted in the supply to the boiler.
‘Hard’ water areas
The temperatures within the heat exchanger are limited by the
boiler control system to minimise scale formation within the hot
water pipework. However, in areas where the water is ‘hard’ (i.e.
more than 200 mg/L of calcium carbonate), it is recommended
that the hot water setting is reduced and that a scale reducer is
fi tted, refer to the manufacturer’s instructions or consult the local
water company for additional advice.
Domestic water fl ow rate
The domestic hot water fl ow has a restrictor, factory fi tted, which
reduces the fl ow to a maximum of:
- CaprizPlus 24 ► 8l/min / CaprizPlus 28 ► 10l/min,
Central Heating water fl ow rate
If it is necessary to alter the fl ow rate, the system can be fi tted
with a lockable balancing valve in the main fl ow or return pipes.
