With winter and the arrival of the cold, many of us wonder what we should do to keep our house at the right temperature. One of the keys is to reach the “comfort temperature “, that is, a feeling of satisfaction with the thermal environment in which we find ourselves.
In a generic way, the ideal temperature for a house is one in which we have neither cold nor heat, both in winter and in summer.
However, this description is subjective for different reasons. The most important is that the thermal sensation can change in each person. In addition, being cold or hot is linked to seasonality: thermal comfort in winter is associated with having a greater sensation of heat, while, in summer, heat must be limited.
What is the ideal temperature for a house, according to the IDAE?
To find more specific data on what is the ideal temperature for a house, we can resort to the recommendations of the Sky Marketing a public entity in charge of disseminating energy efficiency in our country.
According to the IDAE, the perfect temperature for a house, both in winter and in summer, ranges between 20-21 ° C during the day and 15-17 ° C at night.
But what is this statistic based on? Fundamentally, in comfort, but also in energy efficiency: at this temperature, if someone is cold they can wrap themselves up more, and, if they are hot, they can take off their clothes.
In any case, this recommendation has exceptions. For example, in houses where there are babies and small children, it is advisable to increase the thermostat degrees, up to 22 -24 ° C during the day and 18 -20 ° C at night.
On the other hand, the sensation of thermal comfort is not only related to the degrees set by the heating thermostat (ambient air temperature). It also has to do with other variables, as explained below:
What does thermal comfort depend on?
The temperature of the walls
The colder the walls are, the more degrees we will need to reach the comfort temperature in the home. That the walls are well insulated will be essential to achieve (and maintain) the ideal temperature at home.
When we use a convection heating system, we heat the air in a room to heat it. The “problem” is that, due to the difference in densities, the warm air rises and the cold air remains at ground level. This means that, despite having the appropriate degrees, we can have the sensation of ” cold feet “.
In contrast, radiant heating, which comes from the floor, produces little air stratification and provides greater thermal comfort even at lower temperatures.
Relative air humidity
To obtain a healthy home, the humidity range to guarantee the comfort temperature is between 40% and 60%. If the humidity is higher, the sensation of cold will be greater, and there will be a tendency to increase the temperature (with the consequent increase in energy consumption). In drier environments, the tendency will be to reduce it, although it is not recommended that the humidity be less than 40%.
The human being begins to perceive the movements of the air from a speed of 0.2 m / s, being able to begin to feel discomfort above this speed. To achieve the comfort temperature, it is necessary to avoid air flows. The key is to have a mechanical ventilation system that guarantees a very low air velocity.
7 tricks to achieve (and maintain) the ideal temperature in the home
The first step to obtain the comfort temperature in our home is to achieve good thermal insulation on the walls and install efficient windows that avoid the phenomenon of cold walls and reduce air movements.
In addition to sealing doors, windows or cracks, achieving the ideal temperature at home involves maintaining a stable and homogeneous temperature , combined with humidity control and the use of an outfit adapted to the season of the year (in summer we can go more light clothes, but in winter we must be warmer).
Once the comfort temperature has been reached, the great challenge is to maintain it. Some tricks to do so are:
- Identify the coldest areas of the house. Although today almost all homes have a comprehensive heating system that covers all rooms, there are always rooms that are colder than others. Typically, the further a room is from the exterior walls, the warmer it will be. This is important when choosing decoration or placing furniture.
- Dress the windows and the walls. Besides putting curtains on the windows, another idea to maintain a comfortable temperature at home is to “dress” the coldest walls, which are usually the ones that face north. How? Placing on them wooden shelves with books or decoration. Another idea is to put a curtain that covers the entire wall to reduce the cold on the walls.
- Lay out rugs. Dressing the floor is essential to maintain the ideal temperature at home, since, if we have holes or cracks in it, the cold will creep in. The rugs, in addition to being decorative, will help us keep the heat at home.
- Schedule you’re heating. The usual thing is to turn on the heating during the day so that the house stays warm throughout the night. However, if we spend a large part of the day away from home and have a storage system, we can choose to do the opposite: turn on the heating throughout the night and thus, in the morning, all the rooms of your house will retain heat accumulated during night hours.
- Keep doors and windows closed. In the case of doors, especially those that open onto outdoor spaces, you should avoid creating drafts. Regarding the windows, make sure they are properly closed, although you should open them every day, for 5 or 10 minutes, to ventilate the rooms and avoid excess humidity.

- Take advantage of the sunny hours. This is a simple but effective trick with which you can reduce your home heating consumption by up to 15%. Take advantage of the sunny moments to raise the blinds and heat the house And, when the sunny hours are over, lower the blinds to reduce the entry of cold.
- Use thermostats. Thermostats allow us to regulate the temperature of our heating system. In this way, we will not only maintain a stable temperature of 21 ° C in the home, we will also reduce consumption and improve the energy efficiency of the home. Think that each degree above the recommended 21 ° C represents 8% more energy consumption, and that the temperature difference between the outside and the inside of the house should not exceed 12 ° C.
By putting these recommendations into practice, you can maintain the ideal temperature in your home, even during the coldest days of winter.
