Rehau has installed an underfloor heating system for a new lifeboat station in Ireland that uses a heat pump to extract energy from sea water. The project at Kinsale has its energy collectors installed with structural concrete caissons built to support the boathouse. More than 1200 m of Rehau Raugeo pipework has been installed in eight of the 18 caissons, which are each 3 m deep to use the tidal flow of the sea.
