VIESSMANN VITOCAL 350-G (master)
20.5 to 42.3 kW (single stage) 41.0 to 84.6 kW (two-stage) 1 Vitotronic 200 control unit 2 Condenser 3 Large area evaporator for an efficient exchange of heat 4 Hermetically sealed Compliant scroll compressor with EVI (enhanced vapour injection) process 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. As early as at the design stage, this system configuration allows for optimum matching of the heat pumps to the heat demand Master/slave system for DHW and central heating
In a master/slave system, the Vitocal 350-G (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 an extremely high COP of up to 5.0, which contributes to its low operating costs. Vitotronic 200 control unit with communication capability Viessmann uses the convenient Vitotronic 200 control unit to ensure standardised operation for all its heat generators. The many functions of this control unit include operation with user prompts, an integral diagnostic system, control of the instantaneous heating water heater and an additional oil or gas boiler, and of course, natural and active cooling functions. Furthermore, the Vitotronic 200 is capable of communicating, and via the Vitocom 300 module, allows the heat pump system to be set up, monitored and optimised over the internet with the Vitotrol app on a smartphone or tablet. Operation with solar power generated on site The Vitocal 350-G heat pump is already prepared for the utilisation of more affordable power generated on site by a PV system. An intelligent control unit ensures maximum consumption of self-generated power while lowering energy costs. Benefits

The Vitocal 300-G is the specialist for large detached houses and apartment buildings. For applications with higher heat demands, the two-stage Vitocal 300-G, based on the master/slave principle, is the right choice
Cascades up to 589 kW It can deliver a heating output from 42.4 to 85.6 kW (brine/water) with ground as the primary heat source, or 56.2 to 117.8 kW (water/water) when using groundwater. If this is not enough, the integral cascade function enables output to be raised to up to 589 kW (water/water) with several Vitocal 300-G units.
This also assures greater operational reliability for the system as a whole. The modular design, with separate compressor circuits, also ensures particularly high levels of efficiency in partial load operation, and enables simultaneous central and DHW heating.
Powerful and reliable
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 coefficient of performance and flow temperatures up to 60 °C
Quiet operation and great performance are not mutually exclusive
The hermetically sealed casing and particularly clever appliance design enable a reduction in noise emissions in the Vitocal 300-G that far exceeds expectations in this output range.
Benefits
1. Brine/water heat pump
4. Sound power level: ≤ 44 dB(A)
5. Integral energy statement
6. Easier handling through small and light modules
