The RELaTED concept for Ultra-low temperature district heating


RELaTED  will define ultra-low temperature district heating systems as: district heating systems that supply heating to the customers at a temperature level where production of domestic hot water requires a supplementary heat source to deliver satisfactory domestic hot water temperatures.
