Grey water heat recovery (GWHR) is one of the significant opportunities for energy savings in student dormitories and seeks to meet the EU environmental strategy. This article performs the results of temperature and flow rate measurements carried out for domestic hot water consumption for two student dormitories in Wroclaw. An energy analysis was carried out for the measurement data with and without circulation system to assess the energy savings from grey water. Results ensure that GWHR system allows to save 53% of the energy in these buildings.
