Andrews solar water heating reduces carbon footprint of new university building
21 m2 of evacuated tubes are part of the DHW installation for a new building at the University of Plymouth.
Andrews Water heaters has supplied a solar-thermal system with 21 m2 of evacuated tubes for the new £11 million Nancy Astor Building at the University of Plymouth. The system is supported by two Maxxflo direct-fired storage water heaters. The building is the new home of the Faculty of Health & Social Work. Hoare Lea selected the Andrews equipment as part of the requirement to achieve a ‘very good’ BREEAM rating. Andrews was able to supply the whole package, which made the design much more straightforward that combining water heaters and solar system from different manufacturers. Hot-water outlets comprise 17 showers, 28 wash hand basins and 10 sinks in the sports facility, academic teaching area, the cafe and includes all WC, cleaners’ and tea-point facilities in the 4-storey office accommodation. The Solarflo evacuated tubes are mounted horizontally on the flat room of the north core plant room about 28 m above the energy centre, which houses the storage water heaters, a 1500 l stainless steel pre-heat unvented cylinder and the other components of the solar-heating package. The complete Solarflo package includes solar controls, pump station, expansion vessels, first fill of heat-transfer fluid and collector mounting accessories.
