Pellets are by far the cheapest energy source. In terms of their energy content, they cost up to 54.2 percent less than extra light fuel oil and 44.8 percent less than gas.
Prices from October 2012: Extra light fuel oil 10.38 cents per kWh, pellets 4.76 cents per kWh.
Objects of comparison:
Heating systems with similar structural prerequisites and comfort.
Basis for calculation:
An average household with an annual energy requirement of 30,000 kWh. The calculation is based on so-called "heating degree days", i.e. the energy demand curve over the winter months. The cellar contains stocks of heating medium to the value of € 1,500. (electricity and gas are available from the mains).
Electricity: until 4 December 2012
LPG: until 26 December 2012
Extra light fuel oil: until 30 December 2012
Gas: until 30 January 2013
Pellets: until 11 March 2013

The most efficient way to save heating costs is to replace the existing oil boiler with a pellet boiler. You need to reckon with a total investment of approximately € 15,000. However, very attractive subsidies are available.
• Energy for drying pellets: approx. 12% of the pellet energy content (using biomass)
• Electricity required for pelleting: approx. 2% of the pellet energy content
• Transport to customer (100 km): approx. 1% of the pellet energy content
• CO2 saving compared with oil heating: 97%
Pellet boilers are recording strong growth in all Austrian states. Here are a few figures from the annual survey of the Lower Austrian Chamber of Commerce, Herbert Hander.
• Worldwide production 2010: 14 million tonnes
• Production in the EU: 9 million tonnes
• Austria is the third-largest pellet producer in the EU
Stimulated by sunlight, trees produce oxygen essential for life. On subsequent combustion, CO2 emissions are just as low as those for natural rotting in the forest. The sensitive equilibrium of the CO2 cycle is preserved by heating with wood.
