Ground source heat pump VWF 57/4 flexoTHERM - 14.4 kW, 3-phase, 400 V + sensoCOMFORT VRC 720 + DHW tank VIH RW300/3BR + passive cooling module VWZ NC 11/4 0010044225

Comprehensive solution for heating and cooling – Vaillant flexoTHERM ground source heat pump

This kit is a ready-to-use solution for efficient heating, cooling and domestic hot water preparation. It includes a Vaillant flexoTHERM VWF 57/4 ground source heat pump with a capacity of 14.4 kW, a sensoCOMFORT VRC 720 system controller, a VIH RW300/3BR hot water tank and a VWZ NC 11/4 passive cooling module. The whole system is designed to work with a lower source in the form of ground collectors, ensuring stable and economical operation for many years.

Efficiency and user comfort

The flexoTHERM heat pump utilizes advanced EVI vapor injection compressor technology, which translates to high efficiency even at low lower source temperatures. This ensures optimal operation throughout the year, regardless of weather conditions. The COP at 10/35°C is as high as 4.7, and the COPd (according to the ErP directive) is 4.07 – this guarantees low operating costs. The integrated cooling function allows for comfortable maintenance of the optimal temperature inside the building even during the summer.

Kit components and their advantages

• Vaillant flexoTHERM VWF 57/4 ground source heat pump: The heart of the system, responsible for extracting energy from the ground and transferring it to the heating installation. It operates on R410A refrigerant and is adapted to work with various types of DHW tanks.
• sensoCOMFORT VRC 720 system controller: Enables precise control of the heat pump and the entire heating system. It offers an intuitive user interface and remote control capabilities.
• VIH RW300/3BR hot water tank: Provides constant access to domestic hot water at the right temperature. The tank design minimizes heat loss and ensures long life.
• VWZ NC 11/4 passive cooling module: Enables efficient cooling of rooms in the summer, utilizing natural physical processes – without additional electricity consumption.

Technical parameters and application

The kit is intended for installation in single-family and multi-family buildings with access to a lower source (ground collectors). The maximum working pressure of the upper and lower source circuits is 3 bar. The device operates at a voltage of 400 V and is characterized by dimensions: height 1183 mm, width 595 mm and depth 600 mm, and its weight is 151 kg. The heating power at temperatures of 10/35°C and 0/35°C is 6.32 kW and 5.28 kW respectively. The ability to remote control increases user comfort and allows for optimization of system operation according to needs.
