Q-Tech presents invisible VIESSMANN, ISH 2023 preview.

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

Valuable surfaces.

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

New space

State-of-the-art 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 space design concepts.

In addition, 1/3 of the usable surface area.

Heating, cooling and ventilation with 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 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: the standardized and pre-configured components of Viessmann Invisible 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 arrangement options for 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 varnish and a version for individual front finishes in the Manufactureline version.

Consistent independence

With Viessmann's Invisible System, you not only gain freedom of organization. This system, complemented by photovoltaics, reduces the residents' dependence on electricity and fluctuating 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 independent devices and connections, only a small usable area remains free. Its use is limited to washing machines and dryers. Viessmann's Invisible system, on the other hand, can create a new space, for a much larger usable area and two rows of cabinets with integrated appliances. For natural lighting and an aesthetic surface finish. The air distributors and lines are hidden in the false ceiling.

Manufacture, Tan individual as their projects.

Experience the freedom of choice when selecting 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: when implementing such surfaces, you have maximum freedom of arrangement and a stable base ensures a safe installation. Remember that Manufaktur's design is intended for use with material that is 16 mm thick.

Inside, ora new generation of modular devices.

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