Green star	Saving energy at home
Green star Claim	A room thermostat controls the heating in your home. If the room's temperature drops below your chosen temperature, the thermostat will switch on. Once the room has reached the chosen temperature, the thermostat will turn the heating off, preventing overheating and reducing energy consumption. This can help reduce your home's energy consumption.
