Saving Energy

The cost of living is increasing - including electricity and gas prices. We have put together some tips on how to save energy at home:

Correct heating and ventilation

  • Do not set the radiators too high (usually level 3 with room temperature around 19 to 20 degrees); in the bedroom it can even be cooler (level 1 or 2). Do not regulate the room temperature by opening the windows.
  • Ventilate properly: in the morning and in the evening, open all windows for about 5 minutes wide and ideally, ensuring a draught. Do not leave the windows tilted, as the rooms will cool down quickly.
  • Never let the rooms cool down completely.

Fridge, freezer, chest freezer

  • Set the temperature correctly in the refrigerator (7 °C in the upper compartment) and in the freezer (- 18 °C).
  • Do not keep the doors of the refrigerator and freezer open for too long but close them again as soon as possible.
  • Defrost your freezer when ice has accumulated. An appliance that is too full promotes ice formation.


  • Load your dishwasher as full as possible to save water and energy.
  • Use the Eco programme of your dishwasher or low temperatures from 45 °C to 55 °C.

Cooker and oven

  • Cook and fry with a lid. This saves time and electricity.
  • With electric cookers (except induction), the cooker can be switched off earlier and the residual heat can be used. This also applies to the oven, because the residual heat is often sufficient for the final preparation.
  • Baking with circulating air saves about 15 % energy compared to top and bottom heat.

Other kitchen appliances

  • Only fill your kettle with the amount of water you actually need.

Washing machine and tumble dryer

  • Wash at low temperatures of 30 °C to 40 °C. This is quite sufficient for normally soiled everyday laundry and also has the advantage that your clothes will last longer.
  • Make sure to fill the device sufficiently.
  • Set a high spin cycle on the washing machine if you are using a tumble dryer. This saves time in the dryer because the laundry is less wet.
  • Even better than a tumble dryer: simply let your laundry air dry. This also works in winter!
  • Use eco programmes: They take a little longer but use less electricity and water.

Other electrical appliances

  • Stand-by mode: Some appliances are always "under power", so it is better to unplug them or use switchable power strips.
  • Replace incandescent and halogen lamps with economical LEDs. They consume up to 90 % less electricity.
  • Don't forget to switch off the light when you don't need it!
  • Do not leave chargers in the socket any longer - they could be secret power guzzlers.


  • Use cold or lukewarm water when washing your hands or brushing your teeth.
  • If you shower at only 37 degrees instead of 40 degrees Celsius, you reduce the energy consumption required to heat the water by 10 percent.
  • Do not leave the tap running continuously when showering or brushing your teeth, but turn it off in between.
