Power and heat – moving toward a greener future with Viessmann

When it comes to sustainable energy systems, there is an inextricable link between power, heat, and mobility. From power generation to storage and consumption, Viessmann offers everything from a single source.

The success story of the Vitovalor PT2/PA2 fuel cell appliance continues:

The fourth generation is the first fuel cell heating system on the market that can be operated with a hydrogen content of up to 20 percent. This makes Viessmann the innovation leader in the use of hydrogen in conjunction with fuel cell technology.

Power and heat are evolving together

With use of fuel cell heating systems, heat pumps, photovoltaic systems, and power storage units, the electrification of heating technology is helping to create holistic energy systems which, when combined, offer considerable benefits to homeowners.

Vitocharge VX3 – here's how it works

We present the latest generation of power storage units – Vitocharge VX3. Discover why and how the future is electrifying us, how heating systems and power generation are evolving together, and most importantly, what makes our new power storage unit so special.

At Viessmann, we offer a complete range of electric heating systems, electric domestic hot water heating, and photovoltaic power storage units. Everything from a single source.

Ecological and economical – supplementary heating systems

Viessmann's comprehensive range now also includes electric DHW heaters and heating systems. The user receives everything from a single source: Efficient energy systems for power generation, power storage units, and intelligent use for heating, cooling and ventilation.
