Biomass wood heating systems

The rising cost of fossil fuels and growing environmental awareness are creating an ever increasing demand for renewable forms of energy. Today heating with wood is an environmentally friendly and economical alternative or addition to conventional heating systems for fossil fuels.

Viessmann advanced wood heating systems achieve emission ratings similar to those of leading heating systems using fossil fuels and meet the strict regulations set out in European clean air legislation.

Design & Technology

Our advanced biomass systems are fully automated and equipped with control and safety devices for reliable, efficient and safe operation with clean combustion.

Wood heating systems are just as safe and reliable as oil and gas heating systems. Equipped with advanced safety equipment and a digital control unit, the system is closely and extensively monitored and regulated – from the supply of fuel through to heat transfer and ventilation.

Thanks to innovative technologies, our advanced wood heating systems achieve emission ratings similar to those of leading heating systems using fossil fuels. What's more, heating with wood is CO2 neutral. Viessmann wood heating systems meet the strict regulations set out in European clean air legislation, making them not just a perfect choice for today, but also a futureproof solution that will continue to perform within the strictest limitations for years to come.

Wood fired boilers

Fuelled by biomass

Biomass is less prone to severe price fluctuations than fossil fuels and, being sustainable and CO2 neutral, makes a significant contribution to preserving quality of life for future generations.

High operating efficiency

With a biomass system, approximately 50 percent of the total operating costs are accounted for by the fuel. Therefore, choosing a high performance wood boiler and using high quality, affordable wood fuel are critical factors when it comes to optimising the economy of your system.

Although the initial outlay for a biomass system can often be greater than for a conventional heating system, the savings made on fuel costs per thermal unit lead to payback of the higher investment outlay within a relatively short time. Your biomass system will operate as efficiently as a heating system for fossil fuels. However, since your fuel is home-grown and sourced independently, your fuel costs will fluctuate less severely than those of conventional fuels.

the Vitoflex family

Versatile and flexible

Our range of wood boilers is ideal for commercial and industrial use, such as in schools, hospitals, district heating networks, wood-processing plants, etc. The heating energy they supply either covers the entire heat demand of the facility or covers the base load when operated in conjunction with an oil or gas boiler for peak loads.

Integrated technology

Thanks to our comprehensive range of technology, it is easy to create a fully integrated system with Viessmann solar thermal collectors, oil or gas boilers and an individual control technology, helping you to optimise your system performance and maximise efficiency.

Fuel flexibility

Wood boilers can be operated using a wide variety of wood fuels with different net calorific values, storage requirements and costs.

The type of fuel chosen depends on the available storage capacity, the system's requirements and the availability of the different fuel types. Since the fuel quality influences the efficiency and service life of the system, good quality, untreated wood with a low moisture content should be selected.

Our range of wood heating systems support a range of wood fuel types including:

  • Pellets
  • Wood shavings
  • Wood chips
  • Mixed wood
  • Wood dust

Sustainable, CO2 neutral heating

When wood is harvested in sustainable forestry, it is a renewable and environmentally responsible source of energy and an important part of sustainable resource management. When wood is burned, only as much CO2 is released as the trees actually absorbed during the course of their life. That's why heating with wood is CO2 neutral.
