product range

Energy-efficient heating, cooling, and ventilation – Viessmann offers system solutions based on renewable and fossil fuels for all applications. From heating systems for single-family homes to large industrial and commercial systems. An overview of the various product groups is available here.

Heat pump

Viessmann heat pumps use energy stored in the ground, ambient air, and water for heating or cooling. Used as the sole heat generator, in combination with solar thermal systems, or in conjunction with oil or gas heating as a hybrid system, heat pumps conserve valuable resources, reducing CO2 emissions and heating costs

Hybrid heating

Viessmann's compact hybrid heating systems combine renewable and fossil energy sources. Photovoltaic systems can also be integrated into the system.

Solar thermal systems

Viessmann solar thermal systems utilize readily available solar energy to generate hot water and backup central heating. This reduces the use of fossil fuels, thereby lowering CO2 emissions and heating costs.

Solid fuel boilers

Viessmann log and pellet boilers use wood, a renewable resource, as an energy source and provide efficient, clean heating.

Photovoltaics

To convert free solar energy into electricity, Viessmann offers photovoltaic systems with perfectly matched components.

Ventilation technology

Viessmann ventilation equipment reliably and exceptionally quietly ensures a pleasant indoor climate. By removing excess moisture, it also prevents mold growth.

Fuel cell

Fuel cells use the principle of combined heat and power (CHP) to simultaneously generate electricity and heat from hydrogen. Viessmann Vitovalor fuel cells only require a gas connection to achieve this.

Energy management

Viessmann sets new standards in energy management with energy storage systems and power and heat management centres.

Connection and control

Transform your system into a digital heating system and control it from anywhere using an app on your smartphone or tablet.

Accessories

Reliable components for your heating system, already optimally matched to Viessmann ex works systems.

Gas heating

Modern Viessmann gas boilers combine proven technology with innovative solutions. Thanks to condensing technology, up to 98 percent of the energy contained in natural and liquefied gas is converted into heat.

Oil condensing boilers

Viessmann oil condensing boilers impress with their high operational reliability and optimal fuel efficiency. This, coupled with the ability to use "green fuel," makes Viessmann oil heating systems promising.

Low-temperature gas boilers

For use in large buildings, commercial and industrial facilities

Low-temperature oil boilers

Economical oil heating systems for large buildings, commercial or industrial properties.

Water heaters

Viessmann water heaters can be combined with various heating systems, including solar thermal systems. They provide convenient and efficient centralized hot water.

Electric heaters

Viessmann electric heaters provide decentralized heating for residential spaces. They complement existing heating systems or quickly deliver heat where it's needed.

Cogeneration units

Viessmann combined heat and power (CHP) plants, fueled by natural gas and liquefied gas, use the principle of combined heat and power (CHP) to simultaneously produce heat and electricity.

Large boilers

For economical hot water and steam production in industrial, commercial, and municipal settings, Viessmann offers Vitomax industrial/commercial boilers. Decades of experience ensure high operational reliability and a long service life.
