Heating and cooling

Heating, cooling and hot water

Heating is responsible for the largest portion by far of the total energy consumption in households. Consequently, the largest saving potential can also be found here, both in terms of energy and money. Energy saving possibilities are numerous.

Save on heating

Small changes, big effects

As is the case in other domains, minimal changes in everyday habits can help save energy also in space heating.
Such changes of habits don't usually cost a penny, don't affect the quality of life or the standard of living - but they can have surprising effects.

Consider these pieces of heating advice:

  • Often, rooms are much to warm. 22 or 23°C are more than enough to feel comfortable. Lowering the room temperature permanently by just one degree cuts energy consumption by 5%.
  • Lower the temperature at night or during the day, when nobody is home.
  • Use thermostats to regulate room temperature.
  • Make sure you air efficiently: shock-air your rooms by opening the windows wide and then closing them again instead of permanently tilting them.
  • Make sure your radiators are not blocked by furniture.
  • If you know your consumption you can control it better and take the necessary steps.
  • Insulate your home e.g. at windows and doors, or even by using curtains in open rooms or rooms with a draft.
  • Do keep up with maintenance, servicing and cleaning of heating systems, e.g. venting radiators, servicing your gas boiler, regulating the boiler correctly, etc.
  • Insulate heating systems, e.g. insulating tubes, using a protective foil when the tubes run along outer walls.

When cooling, try this:

  • Keep the heat out. This is best done by putting up blinds or shades outside.
  • No unnecessary heat sources. Switch off any screens and computers you don’t use at the moment.
  • Moisturise. There is no need to put up an electric humidifier. Spray a little water in the air every once in a while. This will immediately cool your home down.

Please note: if you decide to take measures and change your habits, make sure you stick to your resolutions and carry them through consistently. Just doing it once is not enough.

Saving energy on heating water

Heating water also requires a lot of energy. Simple measures can yield substantial savings. Here are a few recommendations:

  • Use your hot water boiler efficiently. Read the instruction manuals and use the controls to better set and regulate appliances.
  • Maintenance, servicing and cleaning of the hot water boiler, e.g. regularly decalcifying, are important.
  • Use water-saving shower heads and flow regulators on faucets.
  • Turn off hot water when not needed, e.g. while brushing your teeth or before and after showering.
  • Even if it sounds unlikely, an efficiently used dish-washer consumes far less energy than is needed for washing your dishes by hand.
