With variable output adjustment, the Vitocal 250-A PRO is a heating and cooling solution that can be tailored to individual project requirements in larger residential and commercial buildings and businesses. One appliance generates up to 39.5 kW of heating output. A cascade arrangement with up to four appliances is designed to accommodate larger outputs. Only one indoor unit is required for this.

Vitocal 250-A PRO air source heat pump for an apartment building
Vitocal 250-A PRO – large heat pump for large properties, apartment buildings and commercial applications.
The Vitocal 250-A PRO compact air source heat pump provides heating, cooling and hot water. For this purpose, the sound-insulated outdoor unit quietly and efficiently uses the outdoor air as a heat source. A scroll compressor with variable output adjustment and electronic expansion valves ensure a flow temperature of up to 70 °C with very high efficiency, leading to low consumption costs.
The indoor unit of the Vitocal 250-A PRO has many different functions. Up to three mixed heating/
cooling circuits and a seasonal buffer cylinder are included. DHW can be produced using a cylinder loading system or pump. Instead of a DHW cylinder, the Vitotrans 353 freshwater module can also be used, which conveniently produces DHW according to the instantaneous water heating principle.
If required, an external heat generator can be integrated to cover the peak load.
This enables the heat pump and the hydraulic system to be monitored and controlled from
a central control centre. All essential values can be checked and adjusted from anywhere via a standard BACnet/IP or Modbus TCP/IP connection. Alternatively, hardware contacts are available for external control.
