Product detailed description
Heat pump Vaillant flexoCOMPACT exclusive VWF 88/4
Vaillant flexoCOMPACT exclusive VWF 88/4 is a medium-performance member of the flexoCOMPACT exclusive range – a ground-source heat pump (brine/water) with an integrated stainless steel hot water tank with a volume of approx. 185 liters in one compact cabinet. Like its siblings VWF 58/4 and 118/4, the entire unit is installed indoors – the compressor, heat exchanger, hydraulics and hot water tank are all together in one cabinet with dimensions of 1868 × 595 × 720 mm, which takes up approx. 0.35 m² on the floor. Only the brine circuit leading to the ground collector or borehole runs outside the house.
The VWF 88/4 model is suitable for medium-sized family homes with standard heat loss, where the 58/4 model is no longer sufficient, but the full performance of the 118/4 model would be unnecessarily oversized.

- Heating capacity at B0/W35 (ΔT 5 K, EN 14511): 8.82 kW
- Power consumption at B0/W35: approx. 1.82 kW
- COP (heating factor) at B0/W35: 4.84
- Refrigerant: R410A
- Integrated hot water tank: stainless steel, volume approx. 185 liters
- Dimensions: 1868 mm (h) × 595 mm (w) × 720 mm (d)
- Floor space: approx. 0.35 m²
- Weight: approx. 205 kg (empty unit)
- Energy efficiency class for heating: A+++ at 35 °C / A++ at 55 °C
- Control: equithermal controller sensoCOMFORT (VRC 720) included in the package
- Internet gateway: VR 940f with myVAILLANT app for remote management
- Active cooling: standard integrated for summer cooling of the interior
Why the compact "2 in 1" solution
By combining the heat pump and hot water tank into one cabinet, you save space in the boiler room compared to a combination of a separate pump and upright tank, shorten the installation piping between the units and also reduce heat losses on the short connecting pipe. The tank with a volume of approx. 185 l easily covers the needs of a household with multiple bathrooms.
Controller sensoCOMFORT 720 and internet gateway VR 940f
The package includes the equithermal controller sensoCOMFORT of the VRC 720 range, which controls the pump's performance according to the outside temperature, schedules heating and hot water preparation time programs and communicates with other components via the eBUS bus (e.g. mixing module for the second circuit). The internet gateway VR 940f connects the system to the home WiFi network and makes it accessible via the free myVAILLANT app – setting the temperature, time programs, operating modes (comfort, reduction, vacation) and alerts about possible faults are available directly on your mobile from anywhere.
Summer cooling
The flexoCOMPACT exclusive model has standard active cooling – in summer it can reverse the refrigeration cycle and gently cool the interior via underfloor heating or suitable fan coils, which brings pleasant comfort even during hot months without the need for separate air conditioning.
Installation and heat source
For a performance of 8.82 kW, a geothermal borehole with a depth of approx. 90 – 130 m (according to the geological assessment) or a sufficiently large ground collector is most often designed. An accurate design of the heat source must always be prepared by a professional company based on the actual heat loss of the house. Thanks to the absence of an outdoor unit and low noise, it is also suitable for buildings with stricter noise requirements towards neighbors. 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 the second (e.g. radiator) heating circuit
- Remote room control / room temperature sensor
- Set for photovoltaic control (smart grid ready)
Who is VWF 88/4 suitable for
This model is a good choice for a standard family home with medium heat loss (approx. 7 – 9 kW), where you want to have a performance reserve even on colder days, but without unnecessary overdimensioning and higher initial costs of the largest model in the range.
Frequently asked questions (FAQ)
What is the difference compared to VWF 58/4 and 118/4?
It is the same construction and cabinet dimensions, the compressor power differs – 88/4 is the middle step in the performance range (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 cabinet of the device.
Do I need an outdoor unit?
No, the entire device is inside the building, only the brine pipe to the ground source leads outside.
Can it be cooled in summer?
Yes, active cooling via the existing heating system is a standard feature of the model.
Who ensures commissioning?
Exclusively by an authorized Vaillant service technician, who also confirms the warranty conditions.
Quiet operation and Sound Safe technology
flexoCOMPACT exclusive has no outdoor unit or outdoor fan, so the noise of the device practically does not spread outside and no operational noise from the garden reaches the neighbors. Thanks to the acoustically insulated cabinet (Sound Safe technology), the operation is quiet even directly in the technical room, which is especially appreciated by households with a boiler room close to living areas.
Comparison with air-source heat pump
The temperature at a depth of several meters below the surface of the earth is almost constant throughout the year (approx. 8 – 12 °C), while an air-to-water heat pump has to work with decreasing temperature of the inhaled air on frosty days, and thus also with lower performance and efficiency precisely when the need for heat is highest. The ground-source flexoCOMPACT exclusive, on the other hand, maintains a stable performance and COP throughout the entire heating season, which translates into lower operating costs throughout the year.
Grants and return on investment
Under renewable energy support programs (e.g. Green Home), it is possible to obtain a state grant for ground-source heat pumps in certain periods – current conditions and the amount of the contribution are recommended to be verified before purchase, as they change over time. The high and stable efficiency of the ground-source heat pump compared to a gas boiler or direct electric heating usually means a faster return on the initial investment due to lower annual energy costs.
Requirements for the technical room
The device requires a dry, frost-resistant room with the possibility of discharging any condensate and sufficient space for service access from the side and front. Despite the integrated hot water tank, the cabinet occupies only approx. 0.35 m² on the floor due to its height, which is a very compact solution for a performance of almost 9 kW.
Service and warranty
The heat pump must be commissioned exclusively by an authorized Vaillant service partner, who will perform the connection, set up the regulation and check the functionality of the entire system including the heat source. A regular annual service inspection prolongs the life of the device and is usually also a condition for the extended warranty. Thanks to the internet gateway VR 940f and remote diagnostics, the service technician can often resolve minor faults or check operating values remotely before the physical visit.
The parameters mentioned 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 sizing 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.
