To save on heating costs, aim for an optimal indoor temperature between 18 and 22°C, preferably not exceeding level 4 on the thermostat valve. Level 3 is often sufficient for most cases, potentially leading to up to 20% energy savings when properly regulated.
For optimal comfort, the room you frequent the most should ideally be heated to 19 or 20°C. During sleep, consider lowering the temperature to 16 or 17°C. Additionally, activate the frost protection mode when away from home for an extended period.
Note that the thermostat valve serves as a mini-thermostat on each individual radiator, detecting ambient temperature and regulating the device’s power by adjusting the hot water flow. The valve opens wider as the temperature difference increases, gradually closing as the gap diminishes. This independence allows the radiator to reduce heat input until the desired temperature is reached, leading to water circulation interruption and radiator shutdown.
In conclusion, mastering the art of thermostat adjustment not only ensures a comfortable living space but also contributes significantly to energy efficiency and cost savings.
