Answer: yes, a thermostat allows energy savings of 10 to 25%.
On the one hand there are thermostats built into the radiators, they all have them by default including the oldest, which allow you to regulate the temperature of each radiator. And there are also room thermostats for the entire home that must be installed. Both versions offer you the possibility of modulating the temperature of the accommodation according to your needs. Rather than constantly providing the same temperature regardless of the time of day or night, your heating system adapts at all times according to the chosen commands. So yes, a thermostat allows you to save energy. To give an order of magnitude, you can save at least 10% to 25% on your energy bill. You too, send us your brico question
