DUWO is the largest corporation in student accommodation in the Netherlands and operating in the urban agglomeration (Randstad) and middle of the Netherlands.The student accommodations located in the centre of the university city of Leiden was identified by DUWO to install their first two Q-ton CO₂ heat pumps from Mitsubishi Heavy Industries.
The building consists of identical blocks, each accommodates 160 students and consumes 10,000 litres of sanitary hot water per day.One part is still utilising a gas boiler, while the other part is using the MHI’s Q-ton system to supply the domestic hot water to the students.
DUWO’s main reasons to install a highly efficient system was to make sustainable solution instead of using gas and to improve the efficiency and reliability.The Q-ton solution from Mitsubishi Heavy Industries was installed by Vink installers. Q-ton is not only used for the supply of the sanitary hot water but also to reheat the distribution circuit in the respect of the local anti-legionella regulation.
DUWO in the city of Leiden is very pleased with the results as the efficient stand alone MHI Q-ton solution produces enough hot water at all times of the day under cold climate conditions making this convenient for students
