In winter, maintaining an ideal interior temperature without weighing down the energy bill is a subtle balance. A too cold house exposes health risks, while excessive heating leads to costly overconsumption. However, certain habits, well anchored, harm both comfort and wallet. The thermostat ill -adjusted, insufficient ventilation or poor distribution of heat: these common errors can be avoided by adopting some simple, but essential adjustments.
The first is to adjust the thermostat too high, thinking that a higher temperature will heat the house faster. However, excessive heating only increases consumption unnecessarily, without accelerating the rise in temperature. Each additional degree represents between 5 and 10% more energy expenditure, according to the Institute for energy savings and energy diversification (IDAE), relayed by Jeuxvideo.com.
Another frequent error: poorly manage ventilation. A house must be ventilated daily, even in winter, to avoid the accumulation of humidity and improve the efficiency of heating. A humid part requires more energy to be heated, which directly impacts consumption.
Finally, poor heat distribution can create cold areas and encourage the thermostat. A radiator obstructed by furniture or curtains does not properly diffuse heat. Likewise, not adapting the temperature according to parts is a source of waste.
An interior temperature ideal for your well-being
The optimal heating adjustment does not only concern thermal comfort, it also plays a crucial role on health. According to the World Health Organization (WHO), an interior temperature below 18 ° C increases the risk of respiratory and cardiovascular diseases, especially in vulnerable people.
Cold air can irritate the lungs and cause vasoconstriction. This reaction increases blood pressure and the risk of vascular accidents. In children and the elderly, cold also weakens the immune system, making infections more frequent.
To maintain a healthy environment, WHO recommends at least 18 ° C for healthy adults. For infants, the elderly and chronic patients, the ideal temperature is between 22 and 24 ° C. At night, it can drop slightly, but without going down under 16 ° C in the rooms.
The humidity also plays a key role. It must be maintained between 40 and 50% in winter to avoid the proliferation of bacteria and mold. Too dry air can dry up the mucous membranes and promote respiratory infections.
How to adjust your heating without waste?
It is possible to reconcile ideal interior temperature and energy savings by applying some good practices. First, programming your heating according to its lifestyle is essential. The recommended temperature varies depending on the use of parts:
- 21 to 23 ° C in living rooms like the living room, where we spend the most time during the day.
- 18 to 20 ° C In the rooms, a lower temperature favoring better quality sleep.
- 16 to 18 ° C in the kitchen, where the heat of the cooking devices compensates for the need for heating.
- 22 to 24 ° C in the bathroom, but only during use.
A programmable thermostat adapts these settings according to schedules. It is recommended to lower the temperature at night and in the event of prolonged absence, without however descending under 15 ° C to avoid the risk of condensation and humidity.
Insulation also plays a key role in thermal regulation. A poorly insulated house lets out a large part of the heat, forcing to compensate by excessive consumption of heating. Installing double glazed windows, isolation of the attic and checking the waterproofing of doors and windows helps reduce heat losses and improve comfort without overconsumption.
Finally, the use of intelligent equipment, such as connected thermostats or automatic regulation radiators, facilitates room temperature control by part. These solutions optimize heating while avoiding unnecessary temperature differences.
