Geothermal heat pump VWF 157/4 - 11.2 kW, 3-phase, 400 V + sensoCOMFORT VRC 720 + DHW storage tank VIH RW400/3BR + passive cooling module VWZ NC 11/4 0010044228

Comprehensive heating and cooling solution – Vaillant flexoTHERM heat pump

This kit is a complete heating solution, utilizing energy from the ground, ideal for both new and renovated buildings. The system based on the Vaillant flexoTHERM VWF 157/4 geothermal heat pump provides efficient heating, cooling and domestic hot water preparation. The kit includes all the necessary components for smooth operation, including the sensoCOMFORT VRC 720 controller, the VIH RW400/3BR DHW tank and the VWZ NC 11/4 passive cooling module.

Efficiency and user comfort

The VWF 157/4 heat pump is characterized by high energy efficiency, confirmed by a COP of 5.37 at temperatures of 10/35°C (according to EN 14511 standard). This allows for significant reduction of heating costs compared to traditional systems. In addition, the integrated cooling function allows for comfortable maintenance of the optimal temperature inside the building also in the summer. The sensoCOMFORT VRC 720 controller enables precise system control, as well as remote management via a mobile application.

Construction and application

The system is designed to work with a lower source in the form of brine or groundwater. The maximum working pressure of the upper and lower circuits is 3 bar. The device operates on the R410A refrigerant. The use of the VIH RW400/3BR tank provides comfortable access to 375 liters of domestic hot water. The VWZ NC 11/4 passive cooling module increases the efficiency of the system in cooling mode, ensuring optimal thermal conditions in the building. The whole is enclosed in a housing with dimensions of 595 x 600 x 1183 mm and a weight of 187 kg.
