9 DHW heating
DHW can be heated up in two ways:
–
With a DHW tank: the energy source of the DHW
tank is the heating boiler or a buffer tank
1)
–
With a fresh water module: the energy source of
the fresh water module is the buffer tank
1)
1)
The upper layer area (=drinking water area) in the
buffer is reserved for supplying the DHW tank/fresh
water module.
