calculations and analyzes by Stiftung Warentest show which savings tips actually make a difference and how much savings are achieved overall . The example family saves 1,074 euros per year.
Where the most energy is consumed, the most savings can be made: when showering and heating.
The example family of three switches to an energy-saving shower head. Only 7 instead of 14 liters per minute flow through it. The shower time is also shortened by a few minutes. In total, this saves 2,633 kilowatt hours of electricity per year. Everyone showers a degree cooler and with these measures the family saves 707 euros per year.
To reduce heating costs, the example family uses programmable thermostats. At night and when no one is home, the temperature is reduced. By temporarily lowering the temperature by 4 degrees, you save 7 percent of your heating costs, which is around 95 euros. This change is even more worthwhile in an uninsulated apartment than in an insulated new building. Together with other measures such as using the washing machine's eco program and baking with convection air, the family ultimately saves 1,074 euros a year.
Further savings tips and calculations can be found in the October issue of test magazine and online at www.test.de/energiesparen .
Shower calculator
The consumer advice center has published a “shower calculator” as a helpful tool. With this you can quickly and easily find out how much the shower costs. The calculator also analyzes where and how costs can be saved.
