Forty-seven per cent of Austria is covered by forests so heating using wood is a natural environmentally friendly alternative. Danfoss Nopro has developed and produced a district heating station and surveillance systems for bio-mass systems and has taken part in 250 projects concerning bio-mass heating in Austria. Heating using wood is not only an energy source for large power stations. Nopro has delivered products to projects which supply district heating to only ten end-users in a network. The systems have an extremely high efficiency – as much as 99% which is only feasible because of Danfoss’ thoroughly tested regulation.
