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).
