Alongside output control, the RCD (refrigerant cycle diagnostic) system enables especially precise and fast control of the refrigerant circuit via an electronic expansion valve. Energy saving high efficiency pumps for the brine and heating circuits reduce energy consumption and costs.

Thanks to advanced inverter technology, the Vitocal 300-G brine/water heat pump is the most efficient solution for new build and the best choice for the replacement market.
High efficiency through advanced inverter technology: Vitocal 300-G
Thanks to advanced inverter technology in brine/water heat pumps, the new Vitocal 300-G is the most efficient solution for new build and the best choice for replacing older brine/water heat pumps. The refrigerant circuit, with output-dependent control, matches the heating output of the heat pump to the current heat demand of the building. This results in fewer start/stop cycles in the partial load range and higher annual efficiency. The Vitocal 300-G is available in three output sizes with a modulation range of 1.7 to 8.6 kW, 2.4 to 11.4 kW or 3.8 to 15.9 kW, and therefore covers a wide range of applications for new and existing buildings.
The heat pump combined with a Vitovent ventilation unit offers a particularly high level of comfort and operating convenience. The integral heat pump control unit, or an optional remote control unit, can be used for convenient operation of both appliances. On hot summer days, the heat pump can also cool the rooms. The optional natural cooling box is required for this.

The small footprint of less than 0.5 square metres and front access to all components requiring servicing ensure space saving installation. With its very quiet operation of 41 dB(A) (sound power level to ErP at B0/W55), this heat pump can also be installed near the living space, such as in a utility room.
