Private heating units are not allowed since individual heating is provided in each room. Radiators must not be turned up higher than “3”. Three times per day, the window must be fully opened for between 3 to 5 minutes and then closed, to prevent mold from forming. Cooking units, except kettles and coffee machines, are not permitted in individual rooms. Students are not permitted to tamper with any of the central heating and electrical controls, including fuse boxes unless instructed to do so by the maintenance supervisor.
