The bedroom should be cooler than the bathroom, a child's room warmer than the kitchen. But what temperatures should we aim for to feel cosy and warm and, at the same time, keep heating costs and CO2 emissions low? We summarise the recommendations.
Do you know the rule of thumb that lowering the room temperature by one degree cuts heating costs by about six per cent? So, with one action that you are unlikely to notice in everyday life, you reduce your CO2 emissions and make your housekeeping money go further.
If you are one of those people who have so far heated all rooms to the same temperature, the savings are even greater.
Optimal room temperature for each room
Heating experts, consumer organisations and the Federal Environment Agency therefore recommend that rooms should be heated to different temperatures. Keep the room doors closed in winter to create different temperature zones.
How warm should it be? The guide temperatures are:
- living room: 20 degrees
- dining room: 20 degrees
- child's room: 20+ degrees
- bathroom: 23 degrees
- kitchen: 18 degrees
- bedroom: 17 degrees
Even though every degree lower means you save heating energy and CO2, the aim is always to feel comfortable in your own home. If you feel cold easily, you can and should heat more to reach your own comfort temperature.
Savings potential depending on the time of day
Planning different temperatures for different rooms does not, however, mean keeping them constant round the clock. Quite the contrary:Then the apartment or house does not cool down too much and the temperature can be easily adjusted again after work. Even at night or when you are away for a few days, it makes sense to reduce the temperature: around 16 degrees is usually enough. If you are going on a winter holiday, you can turn down the heating even further. The frost protection function is enough.
