With this in mind, REHAU have improved its RAUTHERMEX range to keep up with industry demand and demonstrate its commitment to net zero progress. The bonded polyurethane (PU) foam of this pre-insulated pipe now achieves a best in class lambda value of 0.0199W/mK, improved from 0.0216W/mK, which equates to around 7-8% heat loss improvement across the RAUTHERMEX range. In addition, the new more profiled outer jacket of the latest generation reduces the bending radius by up to 30% and less force is needed to bend the pipe on site.
This improvement comes as part of a number of developments by the supplier in efficient polymer district heating solutions. With current initiatives like the Heat Networks Investment Project and the Green Heat Networks Scheme set to replace it in 2022, low carbon district heating is fast becoming a viable choice for heating the nation’s building stock. To remain in line with sustainability targets while keeping up with exponentially growing demand for housing, specifiers and developers must be equipped with suitable solutions for delivering entire networks.
Suited to fourth-generation networks supplied by low carbon heat pumps or waste heat sources, specifiers and contractors can utilise a full range of polymer solutions for the entire network. As district heating infrastructure grows across the UK, REHAU has developed solutions applicable to every aspect, including large diameter PP-R pipework for main spines and the NEXUS hot tapping device for reliable connections to existing networks.
