Using the heater properly: tips for saving energy during winter
70 percent of household energy consumption and 60 percent of CO2 emissions are attributable to heating. To heat properly is the best way to save heating costs and protect the climate. Simple measures can help to create a healthy indoor climate and at the same time save money and energy. Here are 5 simple tips on how to heat properly in winter.
The best way to save energy is to insulate the roof and exterior walls as well as windows and doors. But it is also possible to effectively save energy and save money through conscious heating and ventilation. We demonstrate how to do so.
1. How to set the ideal room temperature
Proper heating often means less heating or a more conscious approach to heating. Even a few degrees can make a big difference in energy consumption. According to the consumer association Verbraucherzentrale Bayern energy savings of up to six percent per degree room temperature are possible. A temperature of 20 to 22 degrees Celsius is usually sufficient for the living areas. Often appliances such as cookers and refrigerators heat up the other rooms, so that lower temperatures are sufficient. A bedroom temperature of 17 to 18 degrees ensures a good night's sleep. But it should not be colder than that, because then the risk of mould increases. The heating should not be switched off completely overnight, as otherwise too much energy is required for reheating.
2. Preserve the warmth during the night
Windows do not have the same insulating effect as walls. To heat properly means to let as little heat as possible escape to the outside. If roller blinds are closed at night, heat loss at the windows can be reduced by up to 20 percent. Closed curtains and proper sealing of window and door frames reinforce this effect reducing the heating costs.
3. Regular shock airing
Regular airing during the heating season reduces the humidity in the living rooms and ensures good air quality. The most effective method is so-called shock airing. The most effective method is to ventilate the rooms several times a day (3-6 times a day) with completely open windows for 5 minutes. This allows the air in the room to quickly circulate without the walls cooling down inside. However, continuously partially opened windows hardly provide any air exchange, they cool the walls down. In comparison to permanently partially opened windows, shock airing reduces energy consumption by 30 percent and is also good for your health. Even more energy can be saved by automatic ventilation systems. Smart ventilation with heat recovery can save up to 50 percent of the heating costs.
4. Bleed the heating
If there is air in the radiator, the heater must be bled. Otherwise the warm water cannot rise into the radiator and the heating remains cold. It pays off: If you bleed your radiators once or twice a year, you can save up to 15 percent energy. For information on how to correctly bleed the heater, click here.
Setting the temperature controls
Intelligent as well as networked thermostats are integrated in a so-called Smart Home, which can also be controlled remotely over the Internet. It helps to keep the room temperature at a constant level. It also helps to adjust the heating so that it is ideally regulated according to your needs and circumstances. With Smart Home technology, the heating output is reduced while the window is open, or the sun is shining in. You can save 4 to 8 percent heating energy with modern thermostats. The advantage of adjustable thermostats is that rooms automatically heat up to the desired temperature at the pre-set times. Online weather forecasts and empirical values for room heating can also be integrated into the intelligent heating control system. Smart Home can reduce energy consumption by almost a third. This is not only good for your purse, but also protects the environment and resources.
