Viessmann offers tailor-made system solutions for all energy sources for use in detached houses and apartment buildings. Our comprehensive range includes condensing boilers for oil and gas, micro CHP units with PEM fuel cells and combined heat and power plants.

The range of renewable energy systems features solar thermal systems for heating domestic hot water and to provide central heating backup and cooling. There are also heat pumps that exploit energy from the ground, from groundwater or from the ambient air, plus photovoltaic systems.

The Viessmann modernisation compass – guiding you to the optimum modernisation solution for your heating system

Modernising a heating system is worthwhile. With our modernisation compass, we show you which technical options you have and how these can pay off for you in terms of heating cost savings and subsidies for the respective energy sources.

Product range

Below you will find an overview of Viessmann's extensive product range. Click on a heading to learn more.

Heat pump

Heat pumps are the first choice for those who want to lower their heating bills and generate heat in a more environmentally responsible way. After all, the environment provides the heat pump with the unlimited and free supply of the energy it needs. This fully-fledged heating system needs very little power for its drives and pumps in order to make this energy available. A heat pump makes you independent of fossil fuels, and in addition, actively contributes towards reducing CO₂ emissions and protecting the climate.

DHW heaters

Water heaters

The inner surface of a water heater is crucial for hygienic DHW heating. For this reason, Viessmann relies on two high quality materials: Ceraprotect enamel coating for safe, lasting protection against corrosion in the Vitocell 100 range, and stainless steel in the Vitocell 300 range for outstanding hygiene standards. The Vitocell cylinder range offers you the right DHW cylinder for your specific requirements.
