To minimize energy losses during heat transmission, and to ensure long-term reliability, the client and the designers opted for our tried-and-trusted district heating technology - the pre-insulated, flexible Flexalen pipe system. This proved an ideal solution for the unique challenges to be met. Thanks to the system’s comprehensive range of dimensions, pre-insulated, moulded parts and sophisticated accessories, more than a kilometre of single and double Flexalen pipes were laid. The heating system in the first building and the 14 transmission stations were installed in no time.
Goals
Firstly, the buildings were staggered up the hillside and had height differences of up to 25 metres. Additionally, the pipes had to be laid in cellar arches that were hard to access without disrupting the use of the existing networks. This demanded a high degree of flexibility. The brief from the consultant designers was clear: to build an energy-efficient, corrosion-free, and maintenance-free district-heating network capable of delivering 715 kW of heating power.
Results
The Fuldablick Property Owners’ Association in Kassel had taken on a formidable project. The underground steel pipe network on their 1970s-built residential estate with its 15 buildings and 105 apartments was in need of an overhaul due to the high heat losses that occurred. Replacing the district heating and drinking water network with a system of flexible PB pipes enabled them to reduce heat losses by more than 26%. With the use of our innovative Flexalen pipe system we could support the Fuldablick Property Owners’ Association in achieving energy savings of around 780,000 kWh per year – that’s equivalent to the average annual power consumption of 80 houses!
