In the first construction phase in 1987, the main line was installed. The connections were prepared through butt-welding, and installation was done by trained welders. The excavation/drainage was organized by the cooperative. Meanwhile, with even more conviction from the local community, 18 more homes have been connected.
A long-term solution to make an efficient use of locally produced clean bio-energy for the communal heat supply so that the return on investment could be maximized; that was the main goal for the village of Lichtenegg. They wanted to replace the individual boilers and rely on wood in the form of woodchips instead. Additionally they wanted to improve air quality.
The network has now been operating successfully for 28 years and has expanded since. The last expansion was the connection of 18 houses to the network. The high flexibility of the pipes allowed for a simple and quick installation. 400m and 18 house connections were installed and connected within 8 days. The biomass-fuelled district heating of Lichtenegg sealed by our tried-and-trusted Flexalen system – its excellent, and clearly proven durability being one of the many reasons why it was the best choice.
The high-quality insulation material meant that heat loss could be sustainably minimized. Thanks to the extensive program of dimensioning, pre-insulated fittings, and accessories, the assembly of the system could be realized in a short time with only a few connections.
