It's hot 24 degrees

Basically, the optimal room temperature depends on the purpose of the room itself and the needs of the individual residents. As a rule, it can be cooler in the hallway than in the living room, in which you spend much longer. In addition to your own well-being, ecological and economic factors also play a role in finding the optimal temperature for you. You can find out exactly what makes the ideal room temperature here.

Room temperature and room temperature: what's the difference

Finding the right temperature for you is often not that easy, because the perception of temperature is ultimately individual. Nevertheless, reference values ​​can be set at which most people feel comfortable indoors, not too cold but not too warm either. The room temperature describes this specific guideline value. It is around 20 to 23 degrees Celsius. At these temperatures, people feel comfortable indoors in appropriate clothing.

The room temperature must be distinguished from this in that it describes the value that a thermometer measures. It is made up of the room air temperature and the heat radiation from the surrounding surfaces. A temperature of 18 degrees Celsius can be measured in the hallway, which is below room temperature. You can read in the following sections why this can still be ideal for a space that is only used for a very short time, such as the hallway.

What is the optimal room temperature?

The optimal room temperature cannot be generalized as it depends on numerous factors. The decisive factor is how many people stay in the room, how long and whether they are active. In addition, structural aspects can also play a role: less well-insulated living areas require more heating and a higher room temperature, as it may cool down more quickly.

Optimal indoor temperatures for the different rooms in the house or in the apartment

Basically, it can be cooler in less used rooms than in the rooms in which you spend long and often. The exception is the bathroom. After showering or bathing, it is much more comfortable to be in a warm room. The temperature should be between 23 and 24 degrees Celsius. Choose 22 degrees Celsius for the living area. This means that the rooms are adequately heated without wasting energy. If there are babies or toddlers in a household, these rooms should have a higher temperature; around 24 degrees Celsius. For older children, the normal room temperature can be selected, which is also in the living room.

It is advisable to turn the heating down during the day, especially when you are not at home. Basically, it is best to close the doors to adjoining, rather cold rooms. In this way you do not unnecessarily heat several rooms and less heat is lost.

Reaching these temperatures can sometimes be difficult in summer. Here it is advisable to keep the windows closed during the day and to darken the room so that as little heat as possible can get from the outside to the inside.

Special feature: the right sleeping temperature

The optimal room temperature for the bedrooms is between 16 and 19 degrees Celsius. As a rule, most people only use this room for sleeping. If the workplace is also located here during the day, the temperature must be adjusted accordingly.

The bedroom does not have to be permanently heated. As in all areas of the house, the room temperature should not drop below 14 degrees Celsius to prevent mold from forming. In this context, it is important to ventilate additionally in the morning and in the evening. In this way, especially in the morning, excess humidity can be transported to the outside.

But why should the optimal sleeping temperature be below room temperature? If the temperature is too high, you sweat, sleep becomes restless and many wake up. The air can then also become too dry and mucous membranes dry out. On the other hand, if the temperature is too low, permanent muscle tension can occur. Many will be able to do so, if it is too cold, muscle cramps sometimes occur after getting up. It is best for everyone to test for themselves which sleeping temperature is optimal.

How can the optimal room temperature be achieved?

The appropriate room temperatures can be set differently. This depends, among other things, on your own level of comfort and the technical conditions of the heating system. Basic heating phases and weather-dependent settings are made via the heating control. Individual adjustments for individual rooms and time windows are made using thermostats: room or radiator thermostats.

The classic way that many are familiar with is via the thermostatic head. You will find five levels on most. The following table shows which temperature is behind each. Make sure that this is the target temperature, i.e. the temperature that should prevail in the room. Once this has been reached, no new heating water initially flows through the radiator. The small thermostatic valve regulates this flow.

Save costs and health benefits

The room temperatures recommended by experts have a number of advantages.

  • health: Overheated and dry rooms quickly lead to the mucous membranes drying out. Optimal room temperatures in the range of around 20 degrees Celsius, on the other hand, are good for the airways.
  • save energy: You also make a valuable contribution to resource conservation in the form of adapted room temperature control. By carefully using heating energy, you can protect both the environment and your wallet. In existing buildings that have not been renovated or have not been renovated, one degree less can mean cost savings of around six percent.
  • Reduce the risk of mold: Those who avoid temperatures that are too low counteract the formation of mold. If moisture from the air condenses on cool wall surfaces, the spores could settle on the surfaces. The colder the air in the room, the earlier this happens. Because cold air can carry less water with it than warm air.

Room temperature and comfort

When it comes to the optimal temperature in a room, so-called thermal comfort also plays an important role. Because the term stands for warmth indoors and describes the relationship between different sizes. This is how people perceive the normal room temperature depending on their activity, their clothing, the temperature of the surrounding surfaces and the relative humidity in the room. Researchers have linked all of these factors and developed so-called comfort criteria. The optimum temperature at different degrees of humidity in the air can be read from a special comfort zone. The diagram shows that people feel comfortable in rooms with high humidity even at lower temperatures. The lower the degree of relative humidity, the higher the room temperature should be.

Conclusion by Philipp Hermann

Overall, the optimal room temperature is of enormous importance for a variety of reasons. The acquisition of precisely adjustable thermostatic valves and the definition of individual guide values ​​for individual rooms promise the best results. According to statistical studies, a temperature reduction of one degree already means a cost reduction of around six percent. These figures underline the importance of an ideal room temperature and motivate you to act!
