During the District Heating and Cooling Symposium 2010 in Tallinn Thermaflex presented 5 papers addressing the benefits of flexible pipe systems and tailored prefabricated solutions over the entire network lifetime, exemplified by the pre-insulated piping system Flexalen 600. Since that time Thermaflex achieved a global acceptance of the introduced solutions as they have been successfully implemented in numerous District Heating and Cooling network applications all over the world. This formed the basis for further developments since 2010. Production facilities have been up-scaled to meet an increasing demand and quality level. The cooperation of R&D with key stakeholders focused on responding to their challenges with new and improved solutions.

Awareness of the total costs of heating & cooling networks is rapidly increasing. Optimisation and smart designs offer more options and choices to important added value. Thermaflex focusses on minimizing “total cost of ownership” and maximizing the speed of implementation of these networks. A support program for innovative network design, available to all professional designers/engineers, offers the right solution/tool in combination with Flexalen network concepts.

Heat loss tests are performed on different samples of the Thermaflex Flexalen 600 series and one ST-PUR-PE sample with the Thermaflex heat loss equipment and at two recognized test facilities, both using different test methods. The results of the institute using the same, guarded end method comply with the Thermaflex heat loss equipment’s results. The results of the institute using the calculated end method differ considerably from the Thermaflex results. In this paper a comparison of these methods and results and a verification of the Thermaflex heat loss equipment is given.
