Ground source heat pump heat pump with the option of water/water operation.
Heat pump with a high flow temperature of up to 68 °C
The powerful Vitocal 350-G brine/water heat pump is one of the quietest heat generators of its kind thanks to its low vibration design.
Where heat demand is even higher, the Vitocal 350-G can be operated in two-stage mode with an additional heat pump of the same type, or with a Vitocal 300-G in a master/slave system, and can then provide an output of up to 84.6 kW. At an early stage when planning the system, this configuration allows for optimum matching of the heat pumps to the building in question.
The Vitocal 350-G achieves high flow temperatures of up to 68 °C. This results from the use of an EVI (enhanced vapour injection) refrigerant circuit, where the injection of vapour cools the refrigerant so that it can be more densely compressed than is otherwise possible. This means that the Vitocal 350-G is also suitable for modernisation projects involving radiator heating systems.
Master/slave system for DHW and central heating
In a master/slave system, the Vitocal 350-G, as the master, delivers high flow temperatures for DHW heating, while the Vitocal 300-G (slave, without its own control unit) covers the required heat load. The EVI refrigerant circuit enables the Vitocal 350-G to achieve a very high COP of up to 5.0, which contributes to its low running costs.
Operation with self-generated solar power
The Vitocal 350-G heat pump is already prepared for cost effective operation with self-generated power from a photovoltaic system.
