7 Domestic cold water supply in
The minimum working pressure to obtain the maximum domestic
flow is 1,0 bar.
The boiler is supplied with a pressure reduction valve pre-set to
deliver an inlet pressure of 3.5bar.
‘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
fitted, refer to the manufacturer’s instructions or consult the local
water company for additional advice.
Domestic water flow rate
The domestic hot water flow has a restrictor, factory fitted, which
reduces the flow to a maximum of:
- 35 Store ▸ 16 l/min.
