“Energy Minister Fergus Ewing officially launched the UK’s first SHARC energy recovery system. It intercepts waste water from near a Scottish Water treatment works and uses a heat pump to then “amplify” its “natural warmth”. The system has been estimated to provide 95% of the heat needed by the Galashiels campus.“
