Half-truths about heating costs are popular in times of high energy prices. We have taken a closer look at current heating saving myths and revealed which measures consumers actually use to save energy and which do not achieve the desired result.
Myth 1: Turn off the heating completely when leaving the apartment
Turning down the heating when no one is in the apartment saves a lot of energy. However, living rooms and bedrooms should not cool below 16 degrees to prevent mold. Residents should therefore set the radiator thermostat to level 2 when leaving the apartment. This corresponds to a room temperature of approximately 16 degrees. This means that the heat release is not completely interrupted and mold formation is prevented.
In addition to the night reduction, additional times can be set up on the heating system in single-family homes during which the heat supply is reduced. This makes sense, for example, if you are regularly absent for a long period of time. The heating should then be programmed back to normal heating mode in good time before returning home.
Myth 2: When the heating is turned on fully, a room warms up faster
Would be nice. A heater with a thermostat set to level 3 heats up just as quickly as with level 5. The scale does not indicate the heating output, but rather represents the room temperature reached. On common thermostats with a 5-level scale, level 3 represents a room temperature of 20 degrees Celsius.
The temperature sensor built into the thermostat measures the ambient temperature. As soon as the set temperature is reached, the valve interrupts the heat supply - and only opens it again when the room temperature has fallen below the target value. If you choose the level carefully, you will not only be doing something for the climate, but you will also be saving money. For every degree higher in the room temperature, heating costs increase by around six percent. We therefore recommend not setting thermostats higher than level 3.
Myth 3: Save energy by heating all rooms with just one radiator
Radiators are designed differently for each room and its heat needs. The radiator in the living room is not designed to heat adjacent rooms such as the hallway or kitchen. In order to save energy, it is still tempting to forego the heat output of individual radiators. However, this is a fallacy. If there are several radiators in a living area, all radiators should be set to the same level.
The Bavarian Consumer Center also recommends closing the doors between living rooms with different temperatures and setting the desired room temperature on the thermostat. “Not only does this save energy, it also prevents mold. Otherwise, it easily forms when warm and moist air gets into cooler rooms, such as bedrooms,” says the energy advice from the consumer advice center.
