If it’s not underfloor heating, radiators are often located directly under the window. Placing a desk in front of it not only provides plenty of daylight for work but also keeps your feet warm. While this may be true, it also increases heating costs. This small mistake in setting up can have a big impact on heating the apartment.
Avoid Setup Mistakes and Save on Heating Costs
When setting up an apartment, it’s not just about aesthetics. You should always consider the room as a whole, including planning for the heating. Placing large furniture, such as a sofa, bed, or desk, in front of the radiator significantly impairs heat output. This simple setup mistake can lead to higher heating costs.
Furniture Blocks Air Circulation
When furniture is placed directly in front of the radiator, it restricts heat distribution. The warm air emitted by the heater cannot circulate freely in the room. As a result, the heater has to use more energy to reach the desired temperature, increasing energy consumption and heating costs.

Cold Apartment and Mold on the Wall
If furniture blocks the radiators, the room temperature remains lower than it should be, even with the heater turned up. This can have health consequences. Temperature fluctuations in areas where heat accumulates can weaken the circulatory and immune systems.

If air cannot circulate adequately in the room, humidity levels typically drop, while moisture accumulates behind the furniture. Dry air can lead to dry mucous membranes, coughing, sore throats, or irritated eyes over time. At the same time, damp and cold air is an ideal breeding ground for mold.
Place Furniture Correctly and Save Money on Heating
According to the Federal Ministry for Economic Affairs and Energy, up to twelve percent of energy costs can be saved by sensibly arranging furniture in the room. It’s important to maintain a distance of about twenty centimeters between furniture and radiators. Ideally, large furniture should not be placed directly in front of the heater. A side placement is best, allowing heat to circulate freely in the room.
