Reason no.


Sustainable heating

Pellets are a renewable natural product and, unlike oil and uranium, they will still be available to future generations.

Conclusion: Wood pellets are future-proof!

Reason no.


Environmentally responsible heating

Pellet combustion is CO2-neutral. During the course of their growth, trees absorb CO2 that is released again during combustion – just like natural rotting in the forest.

Conclusion: Wood pellets are a CO2-neutral fuel!

Reason no.


Economical heating

The price comparison makes it clear: Wood pellets, the ecologically clean way to heat, are also economically attractive. Compared with fossil fuels such as fuel oil and natural gas, wood pellets are significantly cheaper. They are not only good for the environment, but also your wallet.

Conclusion: Wood pellets save money!

Reason no.


Resource-saving heating

No additional trees are felled to make pellets. Residual wood from wood processing is used for this purpose. Furthermore, more wood grows back in Austria and Europe every year than is taken out of the forests.

Conclusion: Wood pellets make optimum use of the raw material wood!

Reason no.


Independent heating

Pellets are a home-grown natural product. With wood pellets, you are independent of international crises and global developments.

Conclusion: Wood pellets are always available regionally!

Reason no.


Heating with regional fuel

When purchasing wood pellets, the added value remains in the country. This boosts the domestic economy and creates new jobs.

Conclusion: Wood pellets strengthen our economy!

Reason no.


Convenient heating

Pellets are extremely easy to handle. They can be delivered conveniently by lorry. Charging of the boiler takes place automatically by auger or vacuum suction system and operation of modern pellet boilers is completely maintenance-free.

Conclusion: Wood pellets are the convenient way to heat with wood!

Reason no.


Compact storage

Pellets require only half as much space as logs and only a quarter of that for wood chip. A year‘s supply for a modern detached house can be stored in an area of approx. 4 m².

Conclusion: Wood pellets are a genuine space miracle!

Heating with pellets

Everything depends on the right settings – in two respects: Firstly, you heat with little impact on the climate or the environment and, secondly, a correctly calibrated pellet boiler really saves money.

What do I do for the environment?

Two essential things: Firstly, you protect natural resources, because pellets are a renewable "waste product" of the wood processing industry. Secondly, you protect the climate, because pellet combustion is CO2-neutral.


In other words, you only emit the CO2 that was absorbed during growth. For example, a household burning 4000 litres of fuel oil a year releases 10,442 kg of CO2. An ÖkoFEN pellet boiler only releases 360 kg over the same period. For further details, see Facts & figures.

How do I heat correctly?

Avoid overheating the rooms. Set the thermostat to the most comfortable temperature for you. Info: Increasing the room temperature by only 1 °C consumes about six percent more energy.
Lower the temperature in the building at night. Recommendation: approx. 3 °C lower room temperature between 22:00 and 6:00. This saves heating costs and ensures a good night's sleep!
Ventilate properly. Preferably intermittent ventilation several times a day by opening two windows on opposite sides of the room/house for a duration of approx. three to five minutes. During this period, close the thermostatic valve on your radiator.
Insulate your house well and also rely on the sun for your heat supply. This assures you the lowest possible heating costs for decades to come.



Think about a solar thermal system that can be integrated directly, when laying a new roof covering. A larger system will cover a good quarter of the heating costs.

Maintenance is a prerequisite for highest efficiency for every technical appliance A typical heating system needs to operate at full load for approx. 1500 hours every year. Compared with a car, this corresponds to a distance travelled of approx. 100,000 km. Cars are serviced up to five times over this distance. So treat your heating system to an annual service by a heating contractor and it will repay you with reliable heat.



Pellet boilers are very well-suited to all types of building. Electric heat pumps, on the other hand, are more suitable for highly insulated buildings (<50 kWh/m2 a), exclusively with either underfloor or wall heating. For buildings with 50 to 100 kWh/m2, heat pumps are only suitable to a certain extent and not at all for even higher heat demands. In general, irrespective of the heating method, the combination with solar thermal systems is highly recommended.
