At the heart of the Vitocal 300-G lies its powerful Compliant scroll compressor. This component stands out on account of its high degree of operational safety and reliability. In conjunction with the large heat exchangers and integral refrigerant manifold, the Vitocal 300-G achieves a high COP and flow temperatures of up to 60 °C.

The Vitocal 300-G is ideal for large detached houses and apartment buildings.
The Vitocal 300-G heat pump (21.2 to 42.8 kW) uses renewable heat from the ground or groundwater
The Vitocal 300-G is ideal for large detached houses and apartment buildings. It utilises heat that's right on your doorstep, either with a single-stage brine/water heat pump from 21.2 to 42.8 kW, or with a water/water heat pump from 28.1 to 58.9 kW – each tailored to the specific heat demand.
For apartment buildings or applications that require very high outputs, the two-stage Vitocal 300-G, based on the master/slave principle, is the right choice. It can deliver a heating output from 42.4 to 85.6 kW (brine/water) or from 56.2 to 117.8 kW (water/water). You also have the choice between the groundwater or the ground as your preferred heat source.
If this output is not enough, up to five master/slave combinations can be interconnected via the cascade function integrated in the control unit, which can increase the output to as much as 589 kW (water/water).
The hermetically sealed casing and particularly clever appliance design enable a reduction in sound emissions in the Vitocal 300-G that far exceeds expectations in this output range.
RCD stands for refrigerant cycle diagnostic system. It provides constant monitoring of the refrigerant circuit in the Vitocal 300-G and, in conjunction with the electronic expansion valve, ensures the highest level of efficiency at every operating point.
Especially for a higher heat demand, the Vitocal 300-G is the first choice, because several heat pumps can be linked via the heating flow and return. This not only delivers the high heating output required, but also increases the operational reliability of the entire system. The modular design, with separate compressor circuits, also ensures particularly high levels of efficiency in partial load operation, and enables simultaneous DHW and central heating.
With three output sizes, as a master or master/slave version, the Vitocal 300-G offers various combinations, which can all be precisely matched to the required heat demand. For a higher heat demand, the Vitocal 300-G can be operated in master/slave mode with another heat pump of the same type or with a Vitocal 350-G. A combined master/slave system, for example consisting of a Vitocal 300-G for the required heat load and a Vitocal 350-G for high flow temperatures for DHW heating, allows the heat pumps to be optimally matched to the property right from the design stage.
The availability of different versions and the ability to size according to demand enables optimised runtimes and economical operation. The master module regulates the slave module. By combining different output sizes, system users have the option of matching the environmentally responsible heating system to their specific heat demand as efficiently as possible by utilising different modules.
The EHPA Quality Label serves as proof of the COP (coefficient of performance). The German EHPA Quality Label Committee has confirmed that Viessmann's Vitocal 300-G heat pump meets EHPA Quality Label requirements.
