7.2.3
Functioning as domestic hot water BOILER (DHW)
The BOILER can function as DHW in both seasons – winter and summer.
The DHW request has priority over the heating request in the „winter” mode.
The BOILER can function as instant DHW or as accumulation boiler DHW (the boiler is purchased separately). For the functioning
of the BOILER as an accumulation boiler DHW BOILER please address an authorised service company.
In intant regime, the minimum flow of hot water detected by the BOILER is 2.4 l/min.
For confort in using the BOILER as a DHW BOILER we recommend to exploit the BOILER at a flow of approximately 7-8 l/min.
