- The room temperature of an office should not be above 21 °C. This usually corresponds to the setting 3.5 on the thermostat switch. Every single degree of temperature increase raises heating costs by 6 percent.
- If the room is too warm, please don’t regulate the temperature by opening the window; instead just turn the thermostat down. Please also check that the thermostats on all heaters are set to the same level.
- Regular ventilation must be carried out in order to ensure the exchange of humid air with fresh air. However, please do not continuously let heat escape through open windows. Please try to avoid tilting windows during the colder seasons, as this only serves to cool the walls near the windows thus engaging the thermostat, but barely serves to provided the desired fresh air. Instead, open the windows as wide as possible for 3-5 minutes in winter in order to sufficiently ventilate the room. During this time, turn the thermostat to ‘frost-free’. This way, the room surfaces only lose a minimal amount of warmth and exchange of air in winter takes place very quickly anyway. The room quickly returns to a comfortable temperature once the windows have been closed and the thermostat is once more at the original setting, due to the fact that the walls also emit some heat.
- In order to avoid unnecessary energy consumption outside of working hours, you should turn the thermostat to 2 or 2.5 when you are away from the office for long periods. This ensures that the room temperature remains between 15-17 ° C overnight. This makes it easy to quickly heat the room to the desired temperature at the beginning of the next work day
- The use of an electrical heater should be avoided at all costs, because the use of electricity for heating purposes brings with it considerable costs, as well as environmental pollution. If heating problems arise at your place of work, please inform the technical department.
- Please take care to ensure that radiators are not hidden behind pieces of furniture or other objects / pieces of clothing. This reduces the effectiveness of the radiators and increases the time taken to heat the room. Air must be able to circulate uninterrupted around the radiators.
