5.1 Water Pressure
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 fitted in the supply to
the boiler.
5.2 'Hard' Water Areas
The temperatures within the heat exchanger are limited by the
boiler control system to minimise scale formation within the hot
5 Domestic Hot Water System
water pipework. However, in areas where the water is 'hard' (i.e.
more than 200mg/litre), it is recommended that the hot water
setting is reduced and that a scale reducer is fitted.
Refer to the manufacturer's instructions or consult the local
water company for additional advice.
5.3 Domestic Water Flow Rate
The water flow rate is restricted to a maximum 8 l/min (24cxi)
12 l/min (30cxi) and15.5 l/min (38cxi) by a restrictor fitted during
boiler installation, see diagram 7.1.
