Q-Tech presents invisible VIESSMANN, ISH 2023 preview.

A compact heating and ventilation system that allows for optimal use of the home's space and free use of the building's interior.  The narrow building houses a complete heating and ventilation system.  The devices and system elements are hidden behind individually selected decorative panels and remain invisible.

Valuable surfaces.

Real estate prices are constantly increasing.  Every square meter of living space becomes even more valuable.  The new Invisible heating and ventilation system from Viessmann already offers an innovative solution that allows you to optimally develop and use your valuable space and organize it freely.

New space

State-of-the-art heat pump, ventilation module with heat and moisture recovery, service water tank and complete accessories: Viessmann Invisible integrates all these components into a compact system, thus creating space for new room design concepts.

Also, 1/3 of the usable surface.

Heating, cooling and ventilation in a single, modular and complete solution: the shallow depth and freedom of positioning allow you to create an additional third of free usable space in a room of 11 m².  See page 14/15.

Invisible technique.

Efficiency can be discreet: Perfectly coordinated Viessmann Invisible devices work invisibly and inaudibly behind individually selected decorative surfaces.

Versatile application possibilities.

Benefit from Viessmann's innovative All-in-One solution for single-family homes up to 200 m²: Viessmann Invisible's standardized and pre-configured components make it versatile and simplify the planning and design process.

Slim build.

With a construction depth of only 275 mm, the system takes up very little space.  The various arrangement variants of the modules, in series, in blocks or in corners, always allow for optimal integration into the building.

Individual surface finish.

You can choose between a version in a noble pearl white lacquer and a version for individual front finishes in the Manufactureline version.

Consistent independence

With the Viessmann Invisible system, you not only gain freedom of organisation.  This system, complemented by photovoltaics, reduces residents' dependence on electricity and changing prices.

Gain space, up to 1/3 more usable space: the home laundry room of the future.

The example shows that in a technical and service room with separate devices and connections, only a small usable area remains free.  Its use is limited to washing machines and dryers.  The Viessmann Invisible system, on the other hand, can create new space, for a much larger usable area and two rows of cabinets with integrated appliances.  For natural lighting and aesthetic surface finish.  The air distributors and lines are hidden in the false ceiling.

Manufacture, T as individual as their projects.

Experience freedom of choice when choosing the finish: you can choose the Basis version in a noble pearl white lacquer, or choose the Manufaktur version for individual finishes of the fronts selected by the investor.  Wood, kitchen furniture surfaces or mirrors – when implementing such surfaces, you have maximum freedom of arrangement and a stable base guarantees a secure installation.  Please note that the Manufaktur design is intended for the use of material with a thickness of 16 mm.

Inside, u a new generation of modular devices.

Compact and perfectly adapted to each other.  The heat pump, hot water tank and ventilation combine maximum efficiency with quiet and reliable operation.
