Generate power while you heat

The energy transition and rising electricity prices make the decentralised generation of electricity ever more important. Combined heat and power (CHP) is an important supplement to central power stations.

The government target is to increase the share of power generated by CHP plants from the current 16 percent to 25 percent by 2020. In addition to micro CHP units with Stirling engines, this puts fuel cell boilers at the forefront of decentralised power generation.

Unusually high energy efficiency: Combined heat and power generation

Generating electricity also generates heat, which in central power stations is lost as waste heat. CHP plants using this waste heat for DHW and central heating lets them attain a level of overall efficiency which is twice as high as that of the separate generation of power and heat.

Design & Technology

Our cutting-edge heat and power generation units are the result of more than 25 years' experience in this product area. The Viessmann range offers homeowners efficient gas operated systems for combined heat and power generation. Alongside standard products, we also manufacture combined heat and power units tailored specifically to customers' individual requirements.

As well as being exceptionally efficient, our CHP units use proven technology that ensure maximum reliability, a long service life and user safety.

In addition, our CHP units are also designed with smart homes in mind and come ready for convenient operation by tablet or smartphone, giving you total control from wherever you happen to be.

For industrial applications, we also offer a range of powerful and flexible commercial wood burning systems that are suitable for power generation in biomass CHP units.

Anticipates your needs: self-learning energy manager

Our cutting-edge Vitovalor fuel cell heating appliances are heat led and power-optimised. The integrated energy manager is adaptive and responds to your individual requirements. This means that it only starts the natural gas/hydrogen driven heating appliance when it is worthwhile – when sufficiently long runtimes are expected and therefore corresponding power generation and on-site utilisation.

Independent power generation

Turning away from nuclear power, reducing power generation from coal-fired power stations, expanding the use of renewables...

Whatever your energy objective, innovative heating technologies like the Vitovalor fuel cell boiler bring these goals within reach.

For industrial and commercial applications, a more powerful range of wood burning systems is available, allowing customers to benefit from a renewable, CO2 neutral energy source that is completely independent to the grid.

Vitovalor Fuel Cell renewable heating system.

Efficient heating for larger homes

The Vitovalor offers sufficient thermal output to cover the entire heat demand of a detached or semi-detached homes – on a footprint of just 0.65 square metres. The maximum amount of electrical energy generated over the course of a day (16.5 kWh) is enough to cover the basic needs of an average detached or semi-detached household. The integral gas condensing boiler switches on automatically when the heat generated by the fuel cell module is insufficient, such as at peak times or when a lot of hot water is required for a brief period.

Additional power storage systems

The Vitocharge power storage system from Viessmann raises the on-site consumption rate in a household significantly. If the fuel cell heating appliance generates more power than is currently required, the surplus is generally exported to the grid. However, by combining the Vitovalor with the Vitocharge power storage system, this power can be stored and used at a later time. This translates into a reduction of additional, expensive power drawn from the grid. For more information, go to Energy systems for the Vitovalor.

Benefit from Domestic MCS eligibility

Our Vitovalor fuel cell CHP unit is currently even more attractive due to the availability of payments under the Domestic Micro Generation Scheme (MCS) for small installations.

Benefits of the Viessmann fuel cell heating appliance

  • Up to 30% lower energy bills compared with gas condensing technology
  • Increasing independence of electricity prices by generating power on site
  • PACE funding – making the costs of purchase comparable to those of a gas condensing boiler or solar thermal system
  • Compact design with a small footprint
  • Efficient and environmentally responsible technology of the future
  • High operating convenience via tablet or smartphone
  • Energy efficiency class: A++
  • Energy efficiency class, DHW heating: A
