The <strong>12th</strong> <strong>International</strong> <strong>Symposium</strong> on District Heating and Cooling,September 5 th to September 7 th , 2010, Tallinn, EstoniaPhoto no.: 9 Installation of Flexalen T-LinkPhoto no.:12 Welding of T-Link to the next sectionAll experiences so far have been very positive andhave led to further applications already.RENOVATION IN PURMERENTPhoto no.: 10 Installation of Flexalen T-LinkThese 2 photos (no 8 and 9) demonstrate how easy itwas to slide the connection into the duct under thehouse.Also further connections between the pre-fabricatedsections were made before sliding the entire systemunder the house. Only the last connection had to bemade in the duct. See also photos no.:11 & 12.The situation of the current district heating network inPurmerend (Energy supplier StadsverwarmingPurmerend) is very critical. Due to higher ground waterlevels than expected the current metal pipe systemshave corroded and need to be replaced.As the network has been installed under the basementof the attached housing schemes, the space for theinstaller is very tight and it is not allowed to use anysteel welding process in these circumstances. FlexalenT-Link has been identified to be the ideal solution.Purmerend has ordered this system for 300 houseconnections for 2010 already.For the renovation market in the Netherlands, thissolution has shown big advantages. This solution isnow available for Energy Provider worldwide not justfor renovation, but also for new networks.PRE-FABRICATED NETWORKS FOR NEWPROJECTSPhoto no.: 11 pipes under the buildingThe conditions in new building situations are mucheasier and this solution can help to reduce theconnection costs.Both Dutch Energy Provider, Eneco and Nuon areinvestigating this new solution for new building projects.264
