Short summary
During a shower, a shower heat exchanger from Dutch Solar System can recover more than half of the thermal energy from the heated drinking water. Under a positive condition, installing shower heat exchangers might lead to a reduction of 54 kton CO2 per year in Amsterdam. The research proves the efficiency and potential of the shower heat exchanger, by carrying out experiments in the laboratory and collecting data from the Uilenstede project site, a student housing estate near Amsterdam.
