Heating is the largest energy expense for households. Therefore, it's essential to choose an optimal temperature that balances comfort and energy costs. Making the right choice can have a significant impact on your energy bills and overall home comfort.
According to the Institute for the Diversification and Saving of Energy (IDAE), the ideal temperature for most people during the day is 21ºC. This is considered the most comfortable temperature, offering a pleasant environment without excessive energy consumption. Achieving a comfortable atmosphere is possible without losing control over your heating bills.
Ideal temperature at night
At night, the body needs cooler surroundings to sleep well. Experts recommend lowering the temperature by about 2 degrees from daytime, bringing it to a range of 19ºC to 20ºC. This temperature promotes deeper sleep and reduces the risk of dry air, which can affect sleep quality and the respiratory system. However, experts advise not to go below 17ºC, as extremely low temperatures can be uncomfortable and potentially harmful.
Avoid turning off the heating completely
A common habit is to turn off the heating completely when going to bed, but this isn't recommended. Sudden temperature changes can disrupt the comfort of your home, and restarting the heating in the morning leads to extra energy consumption. It's more efficient to maintain a steady temperature, even if it's a bit lower, to manage both energy use and comfort.
Ideal temperature for children and the elderly
If you have young children at home, you might want to raise the temperature slightly, as children are more sensitive to the cold and spend more time on cold surfaces, like floors and walls. Keeping a warmer temperature ensures their comfort.
For the elderly, who may have a weaker circulatory system, a warmer environment is necessary to help maintain body temperature. During the day, it's best to set the heating between 21ºC and 23ºC for their comfort.
