Q-Tech presents invisible VIESSMANN, preview of the next ISH 2023.

A compact heating and ventilation system that allows optimal use of the space in the house and the free layout of the interior of the building.The narrow building houses a complete heating and ventilation system.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

Latest generation heat pump, ventilation module with heat and humidity recovery, service water tank and complete accessories: Viessmann Invisible integrates all these components into a compact system and thus creates space for new ventilation concepts. space design.

In addition, 1/3 of the useful surface.

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

Invisible technique.

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

Versatile application possibilities.

Take advantage of 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.

Slender build.

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

Individual surface finish.

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

Consistent independence

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

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

The example shows that in a technical and service room with independent devices and connections, only a small usable area is left 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.

Make, as individual as your projects.

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

Inside, aa 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.
