To heat your house as well as possible and thus avoid an excessively high bill, it is necessary to manage the circulation of heat between the rooms well.
As winter approaches and in a context of energy crisis, the heating bill can quickly climb. For a household heated by electricity, this represents up to 40% of total consumption in the early evening or during a cold spell, according to data from the French Environment and Energy Management Agency (ADEME). To limit the amount spent, it is necessary to use its heating well. In this case, it is a practice that is debated. Should the interior doors be closed or not so that the whole accommodation is better heated? It all really depends on the type of installation and your goals.
The first question to ask is that of the interest of heat all rooms to the same temperature. In a small apartment in which you will be moving around a lot, we will seek more uniform heat. It will then not necessarily be necessary to close the doors to keep one room warmer than the other.

Electric heating or wood heating
On the other hand, in a large house, heating can be turned off in unused spaces. In this case, the doors must be closed to prevent a single radiator from overconsuming to heat an area that is too large. This will also allow you to maintain perhaps a higher temperature in the living room than in the bedroom or bathroom.
But above all, the doors must be closed or not depending on your type of heating. In a classic electrical installation with a radiator in each room, it is better to keep them closed. But if you warm up in the woodstove or fireplace, it will be better to open them so that this single source of heat diffuses it throughout the space. To limit energy expenditure and save energy, it is recommended to set the temperature between 14 and 16°C in rooms such as the guest bedroom or the storage room. You can also lower the thermostat to 16°C in the bedroom at night, when you are warm under your covers.
