How to set the ideal radiator temperature? The comprehensive guide to comfort and savings

Good insulation of the rooms.
Knowledge of the optimum temperatures for different rooms.
Method of preparation:

Adjust the optimal temperature: It is recommended to maintain the temperature at 20-21oC in the living rooms and at 17-19oC in the rooms.
Adjust the temperature according to your lifestyle: lower the temperature at night or when no one is at home.

Make sure you purge the air regularly: if your radiators heat up unevenly, it may be necessary to purge them.

Do not cover radiators: curtains, furniture or dry linen limit the circulation of heat.
Service and conservation advice:

Regular maintenance of the system: Have your heating system inspected by a professional each year.
Optimize your consumption: when you are not using the rooms, lower the temperature, but avoid cutting it completely: the reheating requires more energy.
