Should We Really Heat to 19°C? Here’s the Ideal Temperature According to Experts

20°C is a better compromise between thermal comfort and controlled consumption.

Why choose 20°C?
At 19°C, some people still feel a sensation of cold, especially when standing still.
At 20°C, we avoid shivering while maintaining reasonable energy consumption.
For the bedroom, it is better to choose 16 to 18°C.

Maintaining an ideal temperature without increasing your bill is possible with a few simple tips:

Optimize insulation: Close the shutters and use thermal curtains to limit heat loss.
Ventilate daily: Good air circulation helps prevent humidity and improve heating efficiency.
Regulate the temperature according to the time of day:
19-20 °C during the day in living rooms.
16-18 °C at night in the bedroom.
16 °C in rooms that are rarely used (entrance, hallway).
Invest in a programmable thermostat to automatically adjust the temperature.
