Apartment temperatures

The target indoor temperature during the heating period is 20-22°. If your flat feels cold, first measure the room temperature. If the indoor temperature is above 20° and below 23° during the heating period, a fault report may not be necessary. The thermometer in front of the window does not tell the whole story. Instead, measure the temperature in the part of the room you spend time in, about a metre above the floor (at least 60 cm from windows, outer doors and walls).

How to ensure that your indoor temperature and air stay at the desired level:

• Check your radiator thermostat. The radiator thermostat must be open for the radiator to heat the room. If the flat feels cool, check the position of the thermostat, and open it if it is closed. By turning the thermostat down you can reduce the temperature of the flat if it is too warm inside.
• Check that there are no barriers in front of the radiator. For the radiator to heat the room effectively, there must be no furniture, curtains or other barriers in front of it. You cannot tell how well the radiator is working just by touching it, because the human body has a temperature of about 36°, and temperatures below that feel cool. The heating temperature of a radiator is measured with a thermometer.
• Check that the windows are firmly closed and the seals in good condition.
• Check that the air exchange vents of windows and outer walls are in the correct position. The vents should always be open; in winter, they should be in the winter position, if available. If the vents are fully closed, air exchange becomes difficult. In this case, make-up air comes via incorrect routes, such as the letterbox and pipes, and too quickly, causing draughts.

The vast majority of TOAS buildings uses a predictive heat adjustment system. The system controls the heating by taking the indoor temperature, outdoor temperature and weather forecast into account. The system balances the indoor temperature and tries to minimise the effect of weather conditions and seasons. For residents this means a steady room temperature. Especially in spring and autumn radiators are warm in the evening and at night but cool in the morning and daytime. This is because during the day the system predicts the daily high temperatures and the effect of the sun’s heat. Room radiator thermostats can reduce the overheating of flats. Residents may adjust the thermostat and the desired room temperature themselves.
