With Viessmann Invisible, the building services disappear behind a compact pre-wall installation…

Viessmann has surprised the experts at ISH 2023 with a groundbreaking climate solution. Viessmann Invisible combines a heat pump, ventilation module, hot water cylinder and the complete hydraulics in a pre-wall installation just 28 centimeters deep. This gives users a unique space advantage.

The modular system is designed for homes spanning up to 200 sqm of heated living space. It combines the latest-generation Vitocal heat pump, an optional ventilation module, a DHW cylinder and the full set of accessories, including all of the piping, in a compact pre-wall installation that is only 28 centimeters deep. The standardized, factory-configured modules allow for versatile installation options, giving architects and builders alike new freedom when designing the floor plan for a house.

The modules for the Viessmann Invisible are installed without any housing. This gives customers the option of having the front and side wall design customized, choosing from a wide range of materials, such as wood or kitchen surfaces. They can even opt for mirrored surfaces.

The central element of the innovative climate solution is the Vitocal 200-SI heat pump module. The air/water heat pump features a split design and has an output of between 2.6 and 9.0 kW. It is highly efficient with a COP (Coefficient of Performance) of up to 5.0 (at A7/W35 based on EN 14511), giving it an energy efficiency rating of A++. The ventilation module ensures that the ambient air is always clean.
