Hot water storage tank connection
n
QUADRO DU 750 storage tank
In this installation example, the storage tank (type QUADRO DU
750) incorporates a domestic hot water zone. The boiler starts up
systematically to maintain the domestic hot water zone in the storage
tank or to maintain the independent tank at temperature.
If the storage tank does not have a DHW zone, use an
independent domestic hot water tank.
