What is flexoTHERM exclusive and why choose it
The flexoTHERM exclusive heat pump flexibly utilizes energy stored in the ground, groundwater or (in combination with the outdoor unit aroCOLLECT) also in the air, depending on which heat source is available on the site. Thanks to the wide power range of the series (from 5.7 kW to over 19 kW), it is possible to choose exactly the model that matches the heat loss of a particular building – the VWF 87/4 model covers medium-sized single-family homes.
The unit carries the Green iQ label – a mark by which Vaillant identifies products with advanced, sustainable and highly efficient technology with the possibility of intelligent internet connectivity. The high proportion of recycled materials in the cabinet construction and the low operating electricity consumption contribute to a lower carbon footprint of heating.
Thanks to the Sound Safe System, which vibrationally separates the compressor and refrigeration circuit from the unit housing, the flexoTHERM exclusive belongs to the quietest heat pumps in its class – suitable even for technical rooms adjacent to living areas.
Control and remote operation
The system controller sensoCOMFORT 720 with a color touch display controls the entire heating system – hot water preparation, equithermal control, multiple heating circuits and summer mode of active cooling. It allows setting weekly time programs and provides an overview of current consumption and system performance.
The internet gateway VR 940f connects the heat pump to the home WiFi network and the internet, allowing the entire system to be controlled remotely from a mobile app – changing the temperature, heating schedule or hot water preparation is thus available from anywhere. An authorized service technician can also remotely diagnose any potential fault via the gateway.
Installation and heat source
The VWF 87/4 model is connected to a low-temperature heat source according to the geological conditions of the site – a ground loop collector, vertical geothermal boreholes or a well system in the case of groundwater use. The indoor unit is installed in a technical room, boiler room or basement with sufficient space for service access and connection to the heating system (radiators, underfloor heating or their combination).
We recommend combining it with an accumulator water heater with a suitable volume according to the number of people in the household for hot water preparation. Installation and commissioning must be carried out only by an authorized service organization with Vaillant training, which ensures correct regulator setting, hydraulic connection and delivery of the warranty card. We also recommend regular annual service, which extends the life of the device.
Compatible accessories
- Accumulator water heaters (e.g. the uniSTOR, actoSTOR series) in volumes according to household needs,
- Separating and distributing modules fluoCOLLECT for connecting multiple heating circuits,
- Buffer tanks for increasing system storage capacity,
- Accessories for ground collectors or geothermal boreholes (distribution pits, antifreeze mixture),
- Room temperature and humidity sensors for individual heating zones,
- Remote control units sensoCOMFORT for individual rooms.
Frequently asked questions (FAQ)
What size house can the VWF 87/4 heat?
With a properly dimensioned heating system (ideally floor or low-temperature heating), the 87/4 model is suitable for single-family homes with a heat loss of approximately up to 8 kW, which in a new build with good thermal insulation corresponds to an area of approximately 160–220 m².
Can the heat pump also be used for cooling in summer?
Yes, the flexoTHERM exclusive has a standard integrated function of active cooling (natural cooling), which can cool the interior in summer in a mild way via the same distribution that is used for heating in winter.
Is a building permit required for drilling or a collector?
For vertical geothermal boreholes, it is usually necessary to report geological work to the relevant authority, while for a ground loop collector, the administration is simpler. We recommend consulting the exact requirements with the implementation company before signing the contract.
What is the lifespan and warranty?
With regular service, the lifespan of the Vaillant heat pump is typically 20 or more years, the SCROLL type compressor is highly reliable. The product is subject to a 2-year legal warranty, an extended warranty can be agreed with an authorized service partner upon fulfilling the conditions of regular service inspections.
Can the heat pump be controlled from a phone?
Yes, thanks to the internet gateway VR 940f and a free mobile app, it is possible to change temperatures, heating schedules and hot water preparation modes from anywhere with internet access.
Operating costs and savings
Thanks to the high coefficient of performance COP of around 4.0, the VWF 87/4 heat pump produces approximately 4 kWh of heat from 1 kWh of electrical energy, which compared to direct electric heating brings significant savings on operating costs. Compared to air-source heat pumps, the ground or water heat source has a more stable temperature throughout the entire heating season, so the pump maintains high efficiency even on the coldest winter days, when air-source units lose performance. The actual savings depend on the quality of the building's thermal insulation, the setting of the heating curve and the type of metering point (we recommend considering a two-tier electricity rate for heat pumps).
Environmental benefits
The heat pump produces no emissions at the installation site during operation – it does not burn natural gas or other fossil fuels. In combination with a photovoltaic power plant on the roof of the house, it is possible to significantly reduce the indirect carbon footprint of heating. Thanks to the Green iQ certification and low noise, the flexoTHERM exclusive also meets stricter requirements for quiet and sustainable operation in residential areas.
The Vaillant flexoTHERM exclusive VWF 87/4 heat pump with the sensoCOMFORT 720 controller and VR 940f internet gateway is delivered including professional advice on selecting the appropriate heat source and accessories. If you are interested in a specific system configuration (collector, boreholes, hot water tank), do not hesitate to contact us – we will gladly prepare a tailor-made quotation for you.
Modern Heating Systems
Modern heating systems are designed to provide efficient and comfortable heating for residential and commercial buildings. These systems can include a variety of components such as boilers, heat pumps, radiators, and underfloor heating. The choice of system depends on factors such as building size, insulation, and local climate conditions.
One of the most common types of heating systems is the condensing boiler, which is known for its high efficiency and low emissions. These boilers recover heat from the flue gases that would otherwise be lost, significantly improving energy efficiency.
Another popular option is the heat pump, which transfers heat from the air or ground into the building. Heat pumps are particularly effective in moderate climates and can also provide cooling during warmer months.
For larger buildings or those with high heating demands, central heating systems are often used. These systems typically include a central boiler or heat pump that distributes heat through a network of pipes and radiators.
When selecting a heating system, it is important to consider factors such as energy efficiency, initial cost, operating costs, and environmental impact. Consulting with a qualified heating engineer can help ensure that the most suitable system is chosen for the specific application.
Regular maintenance is also essential to ensure the system operates efficiently and safely. This includes checking for leaks, cleaning components, and verifying that all safety devices are functioning correctly.
With the increasing focus on sustainability and energy efficiency, many new heating systems are being designed to use renewable energy sources such as solar or geothermal energy. These systems not only reduce energy bills but also help to minimize the environmental impact of heating.
Overall, the right heating system can significantly improve the comfort and energy efficiency of a building. By understanding the different options available and their respective benefits, building owners can make informed decisions that meet their specific needs and goals.
