Heating costs are rising and at the same time we all want to live more sustainably. Saving energy when heating is therefore an issue that is becoming increasingly important. With a few simple measures, you can noticeably reduce your heating costs and do something good for the environment at the same time. Here you can find out how to heat more efficiently - and still stay cozy.
Why is saving heating energy so important?
Heating accounts for the majority of energy consumption in many households. According to studies, around 70 % of all household energy is used for heating. This means that any savings in this area not only have a big impact on your wallet, but also reduce your carbon footprint.
10 tips for saving energy when heating
1. maintain the optimum room temperature
Every room has its ideal temperature. Too much heating costs money unnecessarily, too little can be uncomfortable
Info: Just 1°C less reduces your heating costs by up to 6 %!
2. bleed radiators regularly
Are your radiators gurgling? Then the heat distribution is not working optimally. Air in the heating system blocks circulation and increases energy consumption. Bleed your radiators at least once a season - this not only saves energy, but also ensures even heat.
3. seal windows and doors
Heat often escapes through leaky windows and doors. You can prevent this heat loss with simple sealing strips or a draught excluder. Thermal curtains or roller shutters additionally increase the insulation effect.
4. use smart thermostats
Modern, programmable thermostats are real savings wonders. You can set them to automatically lower the temperature when you are asleep or not at home. This way, you only heat when you really need to.
5. lower the heating at night
Lowering the temperature at night is ideal: set the temperature in the living rooms to around 15 °C when you are asleep. You save energy without the rooms cooling down.
6. furniture and curtains away from the heating
If you block your radiators with furniture or heavy curtains, the heat cannot circulate properly. Leave enough space for air to circulate to increase the efficiency of your heating.
7. use curtains and shutters
Keep the curtains open during the day to let the sun's heat in and close them in the evening to keep the heat in. Roller shutters also help to keep the cold out.
8. maintain the heating system
A well-maintained heating system uses less energy. Have your heating system checked annually by a professional to make sure it is working efficiently.
9. insulate walls behind the heating system
Reflective insulation foils behind the heating system help to direct the heat into the room instead of losing it into the wall. This measure is inexpensive and can be implemented quickly.
10. energy-efficient refurbishment
If you are planning major changes, think about modern windows, thermal insulation or replacing old heating systems. Sustainable solutions such as heat pumps or solar thermal energy are particularly worthwhile investments in the long term.
