Architects Morgan Sindall was charged with creating a state-of-the art, energy efficient building including the hot water distribution system. A specific requirement was for the system to be able to raise temperatures monthly, for the prevention of legionella. A single-pipe solution was designed, using 1.8km of nVent RAYCHEM HWAT-R self-regulating cables to maintain 60°C. Supported by 15 nVent RAYCHEM HWAT-ECO smart controllers, the necessary legionella prevention cycles could be met, pipe temperatures could be varied (to provide setback temperature savings) and thermal boosts to 65°C implemented during times of non-occupancy.
