Thermostat settings guide for reducing heating costs

Many households misunderstand thermostat settings, leading to unnecessary heating costs. The numbers 1 through 5 on most thermostats do not represent direct Celsius temperatures, but rather define a valve opening that corresponds to a specific temperature range.

According to the Verbraucherzentrale, the temperature intervals between levels are approximately four degrees Celsius. Level 1 corresponds to about 12 degrees Celsius, while level 2 is roughly 16 degrees, which is recommended for bedrooms. Level 3, a commonly misunderstood setting, represents approximately 20 degrees Celsius, the standard for living and working areas. Level 4 is around 24 degrees, and level 5 reaches approximately 28 degrees, which is considered excessively warm.
