Ground source heat pump VWF 197/4 flexoTHERM - 14.4 kW, 3-phase, 400 V + sensoCOMFORT VRC 720 + DHW storage tank VIH RW400/3BR 0010044251

Ground source heat pump – efficient heating and cooling for your home

This system package, consisting of the Vaillant flexoTHERM VWF 197/4 ground source heat pump, sensoCOMFORT VRC 720 controller and VIH RW400/3BR domestic hot water tank, is a comprehensive solution for efficient heating, cooling and hot water preparation in your home. The system utilizes energy stored in the ground, offering savings and user comfort. The heat pump is designed to work with a lower heat source in the form of propylene glycol or ethylene glycol.

Technology and performance for demanding users

The VWF 197/4 heat pump is characterized by a heating power of 23 kW (at 10/35°C) and 19.62 kW (at 0/35°C). A high COP (up to 5.2 at 10/35°C) translates to low operating costs. The Scroll compressor ensures the reliability and quiet operation of the device. Additionally, the integrated cooling function in the pump allows for comfortable use even during the summer. The device is adapted to work with photovoltaic systems (PV Ready function), which allows for further reduction of energy costs.

Intelligent control and user comfort

The sensoCOMFORT VRC 720 controller allows precise management of the entire heating system, including a cascading connection of up to seven devices. Built-in temperature and humidity sensors optimize system operation, ensuring thermal comfort in every room. The ability to control remotely via the sensoNET VR 921 module gives you full control over the system, regardless of your location. The use of the triVAI function allows for intelligent heat management in hybrid systems, adapting the operation of the heat pump to the current energy needs of the building.

Key system features:

• High energy efficiency: COP up to 5.2 ensures low heating and cooling costs.
• Versatility: Possibility of heating, cooling and preparing domestic hot water.
• Intelligent control: sensoCOMFORT VRC 720 controller with remote access function.
• Reliability: Durable Scroll compressor with EVI vapor injection technology.
• Compatibility: Possibility of cooperation with photovoltaic systems and active and passive cooling systems (aroCOLLECT).
• Safety: Maximum working pressure of the upper and lower source circuits is 3 bar.
• Quiet operation: Low sound power level (48 dB(A)).
• Glycol application: Propylene glycol (33%) or ethylene glycol (30%) is recommended for the lower source circuit.

This system is ideal for both new and modernized heating installations, providing thermal comfort and energy savings for many years of use.
