Fürstenfeld

Fürstenfeld
Fürstenfeld heats households and all public buildings with thermalwater Thermalwater can’t be only used for swimming and recreation, this proves Fürstenfeld. It produces hot water from approximately 1.950 meters of depth with about 80 degrees and uses this spring for the public “short-distance heating”.

The heat delivery to the short-distance heating pipeline is made by two heat exchangers made of titanium. The thermalwater is used in a special form, which is called “cascade use” for most diverse purposes and brought in back afterwards again in a reinjectionssonde into 1800 meters of depth. The short-distance heating net is on approx. 10 km long in the central area of the city of Fürstenfeld. This corresponds to a thermal output of 8,5 MW for 150 attached buildings and approx. 100 households.

Inside the earth incredible energy quantities are present. They constant heat flow in direction to the top of the earth correspond to the sun exposure of many millions years. This energy originates from two sources:
1. approximately 30 % of the origin warmth from the birth of the earth about 4.5 billion years ago
2. and approximately 70 % from the decay of natural radioactive isotopes

Energy concept avoids pollutants
The energy concept of Fürstenfeld stands for the improvement of the air quality. Thus an annual reduction of the sulfur dioxide missions, which are responsible for the ozone problem and the acid rain, takes place by 17 tons. That dust content of air, the main reason for pollutants and the connected breath way illnesses, lowered around 4 tons, as well as reduced the carbon dioxide responsible for the greenhouse effect by 7.400 tons. Thus the climatic alliance city Fürstenfeld placed its role of the pioneer in environmental questions under proof and the heat supply of the city on one far into the 3. Millenium handing technological standard posed. The city Fürstenfeld operates also further "solar power plants", like a hydro-electric power plant and starting in 2005 also a biogas plant.

The traffic concept was also referred into the concept of environmental protection. For the improvement of the smell and pollution impact, against high noise disturbance and for the well-being of the resident population in the entire local area the 30-km/h-Zone was introduced.
