Trójka na grzejniku to nie moc grzewcza. Co tak naprawdę oznaczają numery na termostacie?

Resumen del corpus

The numbers on a radiator thermostat do not indicate heating power but rather the target air temperature the device aims to maintain. For instance, a '3' setting generally corresponds to about 20°C, while a '5' setting is around 28°C. Adjusting the setting higher than necessary can lead to overheating and increased energy consumption, as the valve only opens when the room temperature reaches the set level. Experts advise letting the device regulate the temperature automatically for optimal comfort and energy savings.
