Ground source heat pump VWF 157/4 flexoTHERM - 11.2 kW, 3-phase, 400 V, includes sensoCOMFORT VRC 720 controller 0010044244

Geothermal heat pump Vaillant flexoTHERM VWF 157/4 is an efficient heating and cooling solution designed to work with a ground source (geothermal). The device with a power of 11.2 kW, powered by 400 V, is perfect for both newly built and modernized facilities. The set includes an intuitive sensoCOMFORT VRC 720 controller, which allows precise control of the pump operation and optimization of energy consumption.

The flexoTHERM heat pump utilizes energy stored in the ground to heat the building, offering an economical and ecological heat source. Thanks to the high COP (up to 5.37 at 10/35°C) and COPd (4.29), the device provides significant savings in operating costs. The integrated cooling function allows for comfortable maintenance of the optimal temperature inside the premises also in the summer. The ability to remotely control provides full control over the heating system, regardless of location.

Application and benefits:

• High efficiency: COP level of 5.37 (at 10/35°C) translates to low heating costs.
• Versatility: Can be used for both heating and cooling of the building.
• Comfort of use: sensoCOMFORT VRC 720 controller provides intuitive operation and precise system control.
• Ecology: Using a renewable energy source – the ground – reduces emissions of harmful substances into the atmosphere.
• For installers: Compact design (dimensions: 595 x 600 x 1183 mm) facilitates installation and integration with the existing installation. The weight of the device is 187 kg, which should be taken into account during transport and installation. The maximum working pressure of the upper and lower source circuit is 3 bar – important when designing the hydraulic installation.
• Flexibility: Possibility of connection to an open circuit (groundwater) increases the range of applications of the heat pump.
• Active cooling: Provides effective cooling of rooms on hot days, increasing the comfort of using the building.

The Vaillant flexoTHERM VWF 157/4 heat pump uses R410A refrigerant, which is commonly used in such devices. The heating power of the device is from 14.39 kW to 16.68 kW depending on the source and heating medium temperature. Thanks to the solid construction and high-quality components, the heat pump ensures reliable operation for many years.
