Vitocal 300-A is a high-efficiency heat pump with an air heat source of up to 47.2 kW

Viessmann’s Vitocal 300-A is an air-source heat pump with a power range of 13.2 to 55.8 kW. Up to 279 kW of power is possible with up to five Vitocal 300-A heat pumps cascading.

With a high efficiency of up to 4.3 (A7/W35), the outdoor heat pump meets the requirements of convenient heat supply in offices or commercial buildings. Even with an outdoor temperature of -22°C, this unit reaches a flow temperature of up to 64°C.

Two output stages ensure the efficiency of the Vitocal 300-A. Experience shows that about 70 percent of the annual heat load can be covered under partial load conditions. This means that the heat pump works with only one compressor, which allows the highest COP values to be achieved.

Convenient management

The Vitotronic 200 (WO1C) is wall-mounted inside the building, making it easy to commission and operate the heat pump. In a dual-mode system, such as in combination with a gas or oil boiler, the heat pump control unit can automatically start a second heat generator.

In addition, the Vitotronic 200 heat pump control unit is able to communicate and, via the Vitocom 100 or Vitocom 300 communication module, allows you to configure, monitor and optimize the heat pump system via the Internet using the Vitotrol app on your smartphone or tablet.

If Vitocal 300-A is used in commercial applications, it can also be connected to a building management system using Vitogate 200 KNX.
