Autumn time: How to reduce the energy consumption of your home


Saving energy does not just mean putting a lot of money into a heat-insulating cover for the house. There are plenty of other ways you can cut heating costs without much ado during the cold season, most of which do not even require a lot of money. Which energy consumption is normal? And how do you get there?

Which energy consumption is considered "normal"?

Of course, the energy consumption of a home depends on many different factors, including the number of residents, the type of heating and the number of square meters. Therefore the following numbers are only approximate values.

  • low energy consumption: less than 120 kWh per square meter of living space per year
  • average energy consumption: 120 to 200 kWh per square meter of living space per year
  • High energy consumption: more than 240 kWh per square meter of living space per year

With average energy consumption, additional energy-saving measures can make perfect sense. However, if your kilowatt-hour number is high, you should also think about structural improvements.

Ensure tight windows and doors

Are your windows and doors quite old? Porous seals, badly closing window sashes and front doors with draft crevasses increase energy consumption significantly.

Take care of the leaks, dip rubber seals, re-adjust window sashes and install draft stopper under the doors. In the entrance area, you can easily create an effective windscreen by hanging curtains.

Keep the radiator free

The fact that radiators supplied by furniture are much less effective than freestanding room heaters is well known, but this mistake keeps cropping up. So if your sofa is in front of the heater, move it away at least 20 cm.

Cabinets and chests of drawers are not at all in front of the radiators, and drying clothes should not be left lying on the radiator for too long. Overall, the more freely the heated air can be distributed in the room, the better.

Do not forget heating maintenance in autumn!

With regular heating maintenance, energy consumption can be reduced by up to 10% in the long term. The specialist cleans the inside of the heater, restores the technology correctly and replaces wear parts.

Heating expectancy also increases the safety of your system and reduces the risk of total failure in the middle of winter. Those who enter into a maintenance contract with a locally based company often receive emergency help on weekends.

Airing: short and effective

Ventilation is very important in the cold season to carry the increased humidity out of the rooms to the outside. But permanently tilted windows have a very negative effect on energy consumption:

Not only the room air cools off, but also the walls are getting colder. To heat against it, a high energy consumption is needed. In addition, the risk of mold increases in the damp-cool walls.

Ventilate quickly and effectively, a powerful passage of two minutes is enough. Turn off the radiators during this time and then turn them on again immediately. You will see that the room is warm again almost immediately.
