Ground source heat pump VWF 58/4 flexoCOMPACT - 11.2 kW, 3-phase, 400 V + sensoCOMFORT VRC 720 + passive cooling module VWZ NC 11/4 0010044214

Modern heating and cooling with the Vaillant flexoCOMPACT heat pump

The Vaillant flexoCOMPACT VWF 58/4 geothermal heat pump is an advanced solution for efficient heating, cooling and domestic hot water preparation. This system, combined with the sensoCOMFORT VRC 720 controller and the VWZ NC 11/4 passive cooling module, offers independence from traditional energy sources and year-round comfort. The device is designed for both new buildings and the modernization of existing installations.

Efficiency and flexibility in one device

FlexoCOMPACT is a brine-to-water heat pump, characterized by high energy efficiency – COP of 4.7 at temperatures of 10/35°C and COPd of 3.79 according to the ErP directive. The ability to adapt to different heat sources – brine, groundwater or air – thanks to additional modules (available separately), makes it an extremely versatile solution. The integrated hot water tank with a capacity of 171 liters ensures comfortable use.

Advantages for installers:

• Simple installation and intuitive system operation.
• Versatility – adaptability to different ground conditions and user needs.
• Compatibility with other Vaillant devices, such as condensing boilers or heat recovery units.
• Possibility of remote control and monitoring of device operation.

Benefits for users:

• Low operating costs thanks to high energy efficiency (A+++ class for 35°C temperature).
• Thermal comfort all year round – heating in winter and cooling in summer (passive or active cooling function).
• Ecological solution using renewable energy sources.
• Quiet operation of the device thanks to the Sound Safe System.
• Intelligent system control using the sensoCOMFORT VRC 720 controller and the myVAILLANT application.

Design and technical parameters

The flexoCOMPACT heat pump has been designed with durability and reliability in mind. It uses high-quality components and advanced technologies, such as a compressor with EVI technology (direct steam injection), which ensures high efficiency even at low outdoor temperatures. The device is characterized by a compact design (dimensions: 1868 x 595 x 720 mm) and a weight of 151 kg, which facilitates installation and integration with the existing installation. The maximum working pressure in the upper and lower circuits is 3 bar. The heating power at temperatures of 10/35°C is from 6.32 kW to 6.32 kW and at temperatures of 0/35°C from 5.28 kW to 5.28 kW. The refrigerant is R410A. The sensoCOMFORT VRC 720 controller precisely controls the operation of the heat pump, optimizing energy consumption and ensuring thermal comfort in the home. Additionally, the VR921 communication module enables remote access to the system and monitoring of its operation using the myVAILLANT mobile application.
