Questions regarding wood boilers

Köb Holzheizsysteme is aware of its responsibility for the sustained protection of the environment. Its company philosophy and products focus on this.

What types of wood can be used?

Köb wood heating systems can be operated using a wide variety of untreated, high quality wood fuels with different calorific values, required storage capacity and costs. The type of fuel you choose depends primarily on the amount of storage capacity available, the facility's requirements and the availability of that type of fuel in your area. Since the quality of the fuel influences the efficiency and life expectancy of your system, you should choose good-quality, untreated wood with a low moisture content.

How economical is wood heating?

With a biomass system, approximately 50 % of the total operating costs are accounted for by fuel costs. Therefore, choosing a high performance wood boiler and using high quality, affordable wood fuel are crucial 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 heat unit lead to an amortisation of the higher investment outlay within a relatively short period of time. Your biomass system will operate as efficiently as a heating system for fossil fuels. However, since your fuel is from an independent and home-grown source, your fuel costs will fluctuate less severely compared with conventional fuels.

Is wood heating safe?

Absolutely! Today's wood heating systems are just as safe and as reliable as oil/gas heating systems. Equipped with advanced safety and protection features and digital control, the system is closely and extensively monitored and regulated – from the supply of fuel through to the heat transfer and ventilation.

Do wood heating systems provide clean combustion?

Yes! Advanced wood heating systems achieve similar emission ratings as the leading heating systems for fossil fuels. What's more, heating with wood is CO2 neutral. Köb wood heating systems meet the strict regulations set out by the European Anti-Pollution Act.

Where can wood heating systems be used?

Köb wood heating systems are ideal for commercial and industrial use, such as in schools, hospitals, district heating networks, wood-processing plants, etc. They supply either the entire heating energy for your site or the base load if it is being operated together with an oil/gas boiler for peak loads. Thanks to our comprehensive product range, you can expand your biomass system to create a fully integrated system with Viessmann solar thermal, oil/gas boilers and individual control technology.

Can anyone heat with a wood boiler?

The advanced wood boilers from Köb are so convenient to use that they can supply practically any detached house and apartment building with heat. One important requirement is a dry storage room, as the residual moisture in the wood is one of the crucial factors influencing combustion quality. Conversions, for example, of the chimney stack, are generally not required. Wood heating systems from Köb are also a perfect companion for oil and gas heating systems. You can then determine for yourself when to use which fuel.

What is better – heating with logs or pellets?

Logs are an ideal choice for those who can acquire the fuel themselves, e.g. from local forestry operations. The wood needs to be dried correctly, in other words stored until it has the lowest possible residual moisture content. In addition, a heating water buffer cylinder is required to ensure a continuous heat supply. Pellets are created under pressure from sawdust and offer a high calorific value because of their low residual moisture content. Pellets are also easy to deliver and store. Dispensing and supply to the wood heating system is automatic and convenient.

Where can I obtain wood fuel?

Wood fuel, primarily pellets, are today a standard fuel for most fuel merchants. As
with fuel oil, they are "pumped" into the storage room. This is accomplished quickly
and without major effort. Many sawmills and wood processing enterprises also offer
pellets. You can obtain logs at favourable prices from forestry operators or farmers with forestry enterprises attached.
