REHAU’s popular RAUTHERMEX pre-insulated district heating pipework has been installed in the latest phase at the award winning Bluestone holiday resort in Pembrokeshire. More than 1500m of REHAU’s highly thermally efficient pipework is now delivering heat and hot water to 65 new eco-friendly timber frame lodges installed on the site.
RAUTHERMEX was specified on the project after REHAU’s technical design team demonstrated how the pipe sizes required could be cost effectively reduced, just by optimising the flow and return temperatures within the heating and hot water system.
In general, the greater the difference in flow/return temperatures, the smaller the pipe sizes which are required on a heat network project and, at Bluestone, REHAU was able to show how the pipe could be reduced from 125mm to 90mm in places. This made a real impact in terms of the capital cost of the installation and contributed towards reductions in thermal losses.
