Heat pump with water heater and HGW
technology
Description 6.
Connector is an accessory/system solution for customers with large
hot water requirements�
Connector makes it easy to connect a heat pump, with HGW technol-
ogy, with a separate MBH/DWH water heater to maintain a large hot
water volume�
Both hot water heaters in the heat pump and MBH/DWH are connect-
ed in series so that the MBH/DWH water heater is the primary heater
and the built-in heater in the heat pump acts as a secondary heater�
Most of the important hoses, pipes and connectors are included in
Connector installation kit� Some pipes must, however, must be fabri-
cated at the installation site by the installer�
Installation description 7.
The heat pump and MBH/DWH are connected in series by cutting the
water flow
s
from the HGW shunt
e
and allowing it to flow to MBH/
DWH’s connection for hot water charging
i
� The return from the coil
in MBH/DWH is connected to the heat pump’s heater connection, the
inlet to the heating coil
