The Vitoair CT ventilation system is characterized by its space-saving design and particularly quiet operation. It impresses with its flexible installation, user-friendly control and high efficiency. With outputs of 300, 450 and 600 m3/h, rooms from 280 to 750 m2 can be ventilated. Vitoair CT features the Viessmann One Base platform. This enables seamless integration into a Viessmann energy system at any time. The enthalpy heat exchanger regulates the recovery of heat and the exchange of room air and humidity. This prevents rooms from drying out in the winter months and reduces the risk of infection. In summer and during the transitional period, excess moisture is removed from the living spaces to the outside, preventing moisture damage and an unpleasant indoor climate. Collecting pipe components with a nominal diameter of DN 200 enable further applications with increased air volume requirements while maintaining the same air velocity requirements - from the outdoor and exhaust air ducts to the air distribution boxes with Click-and-Go connection plate.

The Vitoair PRO family is the powerful ventilation solution for offices, daycare centers, stores, places of assembly and apartment buildings. The strengths of the Vitoair PRO units include above-average heat recovery and versatile installation options. With air outputs of 600 to 4,000 m3/h, the Vitoair CT PRO has the smallest dimensions and is ideal for niches or corners. Viessmann products can be connected across systems. With the Vitoair PRO Mobile app, the Vitoair PRO ventilation units can be conveniently commissioned using a smartphone. The ventilation solution scores highly with specialist partners thanks to its simple installation. Devices from a size of 2,000 m3/h can be split.

Viessmann Energy Management reduces energy costs and at the same time fulfills the wish of many customers for the intelligent use of self-generated photovoltaic electricity to reduce climate-damaging emissions. The system optimizes the electricity consumption of the heat pump, the charging of electricity storage systems and electric vehicles and guarantees the highest possible level of self-consumption while simultaneously reducing the amount of electricity drawn from the public grid. Energy suppliers have been offering dynamic electricity tariffs since January 1, 2025. Every electricity customer can benefit from low or even negative electricity prices. To do this, electricity must be consumed when it is cheapest. Viessmann Energy Management takes over the control and makes optimum use of the electricity tariffs available at the time.

Users can now choose between the Vitocal 250-A with the best efficiency and maximum convenience or the more economical Vitocal 150-A with an eye on the wallet. Regardless of the Out Door Unit (ODU), the new components always fit together with the In Door Unit (IDU). This high level of flexibility means significantly shorter installation times for tradespeople and users only pay for what they actually need for their heating system. The new hydraulic interface also saves valuable time during installation.
