• Between September 1, 2022, and February 2023, stricter energy-saving regulations were in place for public properties against the backdrop of the energy crisis (room temperature set to 19 degrees). All heating systems were reset to their previous basic settings at the end of these regulations in the first quarter of 2023.
• The optimal temperature is 20 degrees. This typically corresponds to setting 3 on a thermostat scale. However, you can save even more energy by turning down the thermostat when leaving your room. Overnight or on weekends, temperatures of 18 or 16 °C (setting 2.5 to 2) are sufficient. The normal temperature is quickly restored the next morning. This is particularly applicable to rooms where multiple people gather, such as seminar rooms.
• If you plan to be away for several days, you can also reduce the thermostat valves to position 1 or 1.5 (= 12 to 14 °C). In this case, it's advisable to coordinate with your colleagues to ensure the thermostat is adjusted back to a higher setting before your return.
• Avoid placing furniture directly in front of radiators, as it disrupts air circulation in the room.
• Wearing warm clothing in winter helps prevent rapid cooling.

• Keep windows and doors closed - especially when the ventilation is running. This keeps the heat in the room.

How the Heating System Works

The heating water temperature varies depending on the outside temperature. This means that radiators are not as warm when the outside temperature is higher compared to lower outside temperatures. You can set your desired temperature with the thermostat control on the radiator. A temperature sensor in the thermostat compares this with the room temperature and heats the radiator accordingly. Once the temperature is reached, the thermostat valve shuts off the flow to the radiator. The settings on the thermostat only represent the target temperature: your room will not warm up faster if the thermostat control is turned all the way up.

Example: If the room temperature is 16 °C and your desired temperature is 20 °C, it doesn't matter whether you set the valve to 3 or 5; the temperature of 20 °C will be reached at the same time. Setting it to 3 helps avoid unnecessary overheating of the room.
