3.3. Limitations of use

The heating of liquids other than heating water is not permitted (see heating water quality). Heat pumps
are naturally subject to pressure or temperature-dependent operating limits (see diagram below). Operation
outside these limits is not permitted.
The maximum heat pump fl ow temperature is the highest temperature that the heat pump can
produce (depending on the heat source temperature), and at this value it is then switched off .
Due to the hydraulic spread via the heat pump and the control-related switching hysteresis, it is
not possible to reach this temperature in the heating circuit or in the water heater.
The maximum possible operating temperature depends on the hydraulic design and the confi gu-
ration and is at least 5K below the maximum heat pump fl ow temperature.
