Good reasons to use a wood heating system

Fluctuating costs of fossil fuels and growing concern for the environment have led to an increasing demand for renewable energy. Modern wood heating is an eco-friendly and economical alternative (or addition) to conventional fossil fuel heating systems.

Sustainable and CO2-neutral

When harvested in conjunction with sustainable forestry, wood is a renewable and environmentally-responsible form of energy and an important part of sustainable resource management. Burning wood releases as much CO2 as trees absorb in their lifetime. Heating with wood is therefore CO2-neutral and does not contribute to climate change.

Economical, local and independent

As a local energy source, wood is affordable and independent of wide price fluctuations. In times of volatile energy prices, wood remains stable and highly competitive. Wood is harvested with minimal energy input and contributes to the regional economy.

High-tech and reliable

Modern biomass systems are fully-automatic, equipped with advanced control and safety devices and feature state-of-the-art wood heating technologies that ensure reliable, safe, clean and economical operation of the entire wood heating system.


What type of wood can be used?

Viessmann wood heating systems can use a variety of untreated, high-quality wood fuels that vary in heating value, required storage capacity and cost. What fuel type you choose will largely depend on your storage capacity, system requirements and the availability of the fuel in your area. As the quality of the fuel impacts the efficiency and life expectancy of your system, it is best to choose a good-quality, untreated wood fuel with a low water content.

How economical is it?

In a biomass system, the fuel cost is an estimated 50% of the total lifecycle cost. Choosing a high-efficiency wood-fired boiler and high-quality, cost-efficient wood fuel is thus key in optimizing the economy of your system.

Compared to traditional fossil fuels, the average cost per heat unit of wood fuel is significantly lower in most areas in North America. So while the investment cost of a biomass system may in many cases be higher than a conventional heating system, the fuel cost savings per unit of heat can offset the investment in a relatively short timeframe – making your biomass system as economical as or better than a fossil fuel heating system. Plus, with a fuel source that is local and independent, your fuel cost is less volatile than with traditional fuels.

Is it safe?

Absolutely. Today's wood heating systems are as safe and reliable as leading gas/oil heating systems. Equipped with advanced safety and fire protection devices, and a digital control, the entire system is closely monitored and controlled – from the fuel feed right to the heat transfer and venting. Viessmann wood-fired boilers are built to ASME Section IV requirements, are CRN registered, and have been tested to CSA/UL Safety Standards (including all safety controls).

Is it clean-burning?

Yes! Modern wood heating systems, when professionally operated and maintained, reach similar emission levels to leading fossil fuel heating systems. Better yet, wood heating is CO2-neutral. Viessmann wood-fired boilers meet the stringent regulations of the European Clean Air Act.

What applications can it be used for?

Our wood heating systems are ideally suited for commercial and industrial applications, such as schools, hospitals, community heating systems, wood processing plants and more. They are designed to carry either the entire heating load of your system or the baseload, when combined with an oil-/gas-fired boiler for peak times. Our comprehensive product portfolio also allows you to expand your biomass installation into a fully integrated system, complete with Viessmann solar, oil/gas boiler and custom control technology.
