Product detailed description
Heat pump Vaillant flexoCOMPACT exclusive VWF 118/4
Vaillant flexoCOMPACT exclusive VWF 118/4 is the most powerful model in the flexoCOMPACT exclusive series – a ground/water (brine/water) heat pump with an integrated stainless steel hot water storage tank of approx. 185 liters in one cabinet. The compressor, heat exchanger, hydraulics and hot water tank are all together in one cabinet with dimensions 1868 × 595 × 720 mm, which takes up approx. 0.35 m² on the floor. The entire device is installed indoors, only the non-freezing brine circuit leads outside to the ground collector or geothermal borehole.
The VWF 118/4 model is intended for larger family homes or houses with higher heat loss, where you still want to benefit from the compact solution "pump + tank in one cabinet", but need a higher performance than with the 58/4 or 88/4 models.

Why the compact "2 in 1" solution
Combining a powerful heat pump and a large hot water tank in one cabinet saves space in the technical room even in a larger house, where a separate tank with a comparable volume would otherwise take up an additional square meter. The shorter connecting pipe between the pump and the tank means lower heat losses and faster, simpler installation.
Controller sensoCOMFORT 720 and internet gateway VR 940f
The equithermal controller sensoCOMFORT (series VRC 720) is part of the delivery and manages performance regulation according to outside temperature, heating and hot water time programs and communication with other components via the eBUS bus (e.g. mixing module when combining radiators and underfloor heating). The internet gateway VR 940f connects the system to the home WiFi and the free myVAILLANT app, through which it is possible to change temperatures, time programs and operating modes from a phone and receive notifications about possible faults.
Summer cooling
The VWF 118/4 model also has active cooling available as standard – in summer, the cooling circuit in reverse mode gently cools the interior via underfloor heating or fancoils, which is a pleasant bonus especially with a larger heated area.
Installation and heat source
For a performance of 11.18 kW, a typical solution is a geothermal borehole with a total depth of approx. 120 – 170 m (or a pair of shallower boreholes), or a sufficiently large ground collector on a larger plot of land. The exact dimensioning of the heat source must be based on the heat loss of the specific house and the geological assessment of the location. Thanks to the absence of an outdoor unit, it is also suitable for densely built-up areas with strict noise limits. Commissioning is carried out exclusively by an authorized Vaillant service partner, which is a condition of warranty validity.
Compatible accessories
- Module VWZ NC for extended passive cooling (optional, purchased separately)
- Mixing module for a second heating circuit
- Remote room control / room temperature sensor
- Set for photovoltaic control (smart grid ready) for priority use of self-generated electricity
For whom is VWF 118/4 suitable
We recommend it for larger family homes with a heat loss of approx. 9 – 11 kW, where monovalent operation without electric boosting is possible with a properly designed heat source even on icy days, and at the same time you want to save space in the boiler room thanks to the integrated hot water tank.
Common questions (FAQ)
What is the difference compared to VWF 58/4 and 88/4?
Same construction and cabinet dimensions, only the compressor power differs – 118/4 is the most powerful stage of the flexoCOMPACT exclusive series (5.28 / 8.82 / 11.18 kW).
Is the hot water tank part of the package?
Yes, the integrated stainless steel tank with a volume of approx. 185 l is part of the device cabinet and is not purchased separately.
Do I need an outdoor unit?
No, the entire device is inside the building, only the brine pipe leads outside to the ground heat source.
Can it handle a larger house without electric boosting?
Yes, if the heat source is properly designed and the heat loss corresponds to the performance of 11.18 kW.
Who ensures commissioning?
Exclusively an authorized Vaillant service technician, who also confirms the warranty conditions.
Quiet operation and Sound Safe technology
Without an outdoor unit and outdoor fan, the device noise practically does not spread outside, so even with a higher power of 11.18 kW, there is no risk of conflict with neighbors due to noise, which is common with some air-source heat pumps. Thanks to the acoustically insulated cabinet (Sound Safe technology), the operation is quiet even directly in the technical room.
Comparison with air-source heat pump
The ground temperature at a depth of several meters is almost constant throughout the year (approx. 8 – 12 °C), while the performance and efficiency of an air-source heat pump decrease with the decreasing outside temperature – precisely when the house needs the most heat. For a larger house with higher heat loss, for which the VWF 118/4 model is intended, this difference is noticeable in practice especially during icy weeks, when the ground pump maintains a stable performance and COP.
Grants and return on investment
Under renewable energy support programs (e.g. Green Home), it is possible to obtain a state grant for ground/water heat pumps in some periods – current conditions are recommended to be verified before purchase. For a larger house, where the annual energy consumption for heating and hot water is higher, the difference in operating costs compared to less efficient heat sources is more pronounced and the investment in a ground pump usually pays off faster.
Technical room requirements
The device needs a dry, frost-resistant room with the possibility of condensate discharge and sufficient space for service access from the side and front. Even at the highest power in the series, it retains a significant space advantage thanks to the integrated tank and space-saving footprint (approx. 0.35 m²) compared to a combination of a separate pump and a large standing tank.
Service and warranty
The heat pump must be commissioned exclusively by an authorized Vaillant service partner, who will perform the connection, set the regulation and check the heat source functionality. A regular annual service inspection prolongs the device life and is usually a condition for claiming an extended warranty. Thanks to the internet gateway VR 940f and remote diagnostics, the service technician can in many cases check operating values or solve a minor fault remotely before a physical visit, which is an advantage especially for larger installations with higher power.
The stated parameters are based on the technical documentation and energy label of Vaillant flexoCOMPACT exclusive VWF 58 – 118/4 (installation instructions, product data sheet according to EU regulation 811/2013). The exact performance in a specific building depends on the dimensioning of the ground source and the heating system.

Easter Bunny in the logo - intended for the success of the company
Pink dwarfs and cute animals stand around and admire the miracle of the egg. Johann Vaillant is fascinated by the scene and decides to buy both the picture and the copyright. For Vaillant, this means the establishment of its brand and an extremely successful story.
Very distinctive brand profile
Since 1899, the motif has adorned all products, catalogs and brochures. In a few short years, Vaillant built an excellent reputation that spread throughout Germany and even beyond its borders. Vaillant gave its logo clear lines and outlines. "The Bunny in the Egg" remains the central theme, but the word "Vaillant" is added.
Many Germans know that the Vaillant Bunny belongs to a company based in North Rhine-Westphalia. Moreover: more than 70% of all Germans have heard of the company Vaillant. In Austria and the Netherlands, the company achieves similar results for its image.
