Appliance description
The buffer tank and DHW tank with indirect coil are arranged one
above the other and can be separated for easier handling.
The appliance has a plastic jacket with foam insulation and is
equipped with a removable front casing. The appliance is connect-
ed hydraulically and electrically to the heat pump. All hydraulic
connections are made at the top (heating & cooling) and rear
(DHW).
In addition to the DHW tank and the buffer tank, further system
components are integrated:
- Heat pump manager
- Highly efficient circulation pump for a heating circuit without
a mixer
- 3/2-way diverter valve
- Primary tank pump
DHW tank
The tank is steel and coated on the inside with a special direct
enamel and is equipped with a signal anode. The anode with
consumption indicator protects the tank interior from corrosion.
The heating water heated by the heat pump is pumped through
an indirect coil inside the DHW tank. The heat channeled through
the indirect coil is then transferred to the domestic hot water. The
integral heat pump manager (WPM) regulates the DHW heating to
the required temperature.
Buffer tank
This steel tank provides hydraulic separation between the flow
rates of heat pump and heating circuit. The heating water heated
by the heat pump is transferred into the buffer tank by the tank
charging pump. When a demand is issued, the integral heating
circuit pump delivers the heating water to the heating circuit.
Heat pump manager (WPM)
The system is controlled by means of the integral heat pump man-
ager.
Note
The heat pump manager has an automatic summer/win-
ter changeover so you can leave the system switched on
in summer.
Please observe the instructions for the heat pump manager.
