Ground source heat pump VWF 118/4 flexoCOMPACT - 8.8 kW, 3-phase, 400 V + sensoCOMFORT VRC 720 + passive cooling module VWZ NC 11/4 0010044216

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

The Vaillant flexoCOMPACT VWF 118/4 ground source heat pump is a comprehensive solution for a modern heating and cooling system. The unit utilizes energy stored in the ground, offering high efficiency and low operating costs. Complete with the sensoCOMFORT VRC 720 controller and VWZ NC 11/4 passive cooling module, it is a ready-to-install package for your home.

This heat pump is not only for heating – thanks to the cooling function, it provides thermal comfort all year round. The integrated 185-liter hot water tank guarantees a constant supply of domestic hot water. The unit is particularly recommended for well-insulated buildings where energy demand is relatively low.

Technology and efficiency

The FlexoCOMPACT VWF 118/4 is characterized by high efficiency, confirmed by a COP of 5.22 at temperatures of 10/35°C. The EVI vapor injection compressor technology ensures efficient operation even at low source temperatures. The unit is adapted to cooperate with various types of lower heat sources, including an open circuit (groundwater).

It is worth noting the seasonal energy efficiency η(s) of 142% for heating at a supply temperature of 55°C and 201% at a temperature of 35°C, which translates into real savings in heating costs. The sensoCOMFORT VRC 720 controller optimizes the operation of the heat pump, adapting it to current needs and weather conditions.

User comfort and installation

The package includes all the necessary elements for the proper operation of the system: a heat pump, a controller and a passive cooling module. This makes installation simple and quick, and the system is ready to operate immediately after installation. The device is also compatible with other Vaillant devices, such as ventilation units or condensing boilers, allowing you to create a comprehensive energy management system in the building. Additionally, remote control provides full control over the heating and cooling system from anywhere.
