Viessmann is a leading company in residential, commercial and industrial
climate comfort technologies. Founded in 1917 and now part of the Carrier Group, Viessmann specialises in the development of systems for heating, air conditioning, domestic hot water production, controlled mechanical ventilation and renewable energy. Its portfolio integrates high-efficiency energy solutions designed to support the decarbonisation of buildings and intelligent energy management through an approach focused on the integration of building systems, digital technologies and renewable energy sources. The company's vision is centred on creating more sustainable and comfortable living spaces by developing solutions capable of meeting the needs of contemporary construction and the ongoing energy transition.
Viessmann: heating, air conditioning and renewable energy systems
The Viessmann catalogue includes a comprehensive range of technologies for indoor climate comfort. Alongside the
Vitodens family of condensing boilers, developed primarily for the residential sector, the company manufactures
Vitocal air-to-water heat pumps designed for both new-build projects and energy renovation works. The portfolio also includes hybrid systems, heat pump water heaters, biomass boilers fuelled by wood and pellets in the
Vitoligno range, and combined heat and power (CHP) systems for commercial and industrial buildings. Viessmann is also active in the
renewable energy sector with photovoltaic modules, solar thermal collectors, energy storage systems and inverters developed to maximise self-consumption while enabling seamless integration between energy production, storage and intelligent management. The catalogue is completed by the
Vitoclima air conditioning range, Vitoair and
Vitovent controlled mechanical ventilation systems, and underfloor radiant heating systems designed to ensure outstanding comfort, superior indoor air quality and reduced energy consumption. The continuous evolution of the product range is supported by advanced digital control systems that allow the monitoring and optimisation of the entire installation, ensuring seamless integration between all technologies.
The history of Viessmann and innovation in climate technologies
Viessmann's history began in Germany in 1917 as a manufacturer of
heating systems. Over more than a century, the company has progressively expanded its expertise, evolving into a provider of integrated indoor climate and energy efficiency solutions for buildings. This technological development has been driven by continuous investment in research, product innovation and the development of increasingly efficient systems designed around renewable energy. A significant milestone in the company's recent history was Viessmann's integration into the
Carrier Group, creating an international platform dedicated to HVAC technologies. In Italy, this integration is reflected in the "Power Play as One Team" initiative, through which Carrier and Viessmann combine complementary expertise and technologies to offer an even broader portfolio for HVAC and construction professionals. Today, the brand continues to develop climate comfort technologies with a strong focus on energy efficiency, digitalisation of building systems and environmental sustainability, contributing to the transformation of buildings towards increasingly sustainable models.
