Causes of low temperature in the basement.
Content
Many residents of private houses are interested in why it is so cold in the basement, this place with the lowest temperature in the house. In this article we will tell you why this is happening.
Why is the basement the coldest place in the house?
The fact is that the density of cold air is much greater than warm, so it is harder. Its mass is larger, and accordingly it is heavier, accumulates below. Warm air, due to low density, rises. In addition, convection occurs. The fact is that any air that enters the house goes down, due to its high density.
Therefore, during ventilation, most of the cold air enters the basement, where due to thermal insulation, it warms up a little, gradually rises up. This is a natural process on the basis of which the windows are placed in the basements or in the apartment at the top, and not below. This is necessary in order to release hot air through the windows, stimulating the ingress of cool air into the room, its accumulation in the lower part.

In addition, it is not in vain that convectors are placed not at the top, but below, on the floor. Because it is in this area that the air is the coldest, it requires heating. If you measure the temperature in the room, in the ceiling, and below, it will differ slightly. The air that is at the ceiling will be much warmer than the one that is at the floor. These are physical processes that indicate convection occurring in the room. That is, heat exchange.
Most often, the basement is below the ground level, that is, directly underground. It contains thermal insulation, and the air retains its initial temperature for a long time. There are usually no heating sources in the basements, so the temperature there is quite low. This rule is often used when building houses on the slopes. It is in the lower part of the slope that they often build a corridor, pantry or some utility rooms.
Already with an increase in the level of the slope, place the kitchen, as well as living rooms. Most often, the bedroom, nursery, is placed in the highest place of the slope, closer to the surface of the earth or on it. This is done in order to make it easier to warm up the room. Because the rooms that will be below the ground level, that is, in the very lowland of the slope, will be the coldest. They will be cold enough and dampness will constantly accumulate. Therefore, it will be necessary to spend a lot of gas, electricity in order to warm the room.
Initially, these features are taken into account when designing. In the lower part of the slope, utility rooms are equipped, as well as a cellar to spend as little energy as possible for warming these rooms.
