QUESTION: Heating: how to ventilate in winter without cooling the apartment?

Proper ventilation of an apartment in the winter period ensures the inflow of fresh oxygen while completely preserving the heat accumulated in the rooms. The answer regarding heating is always built on compliance with the principles of basic safety and engineering, where the features of ventilation are taken into account, and only then are the elements of decoration and comfort selected to minimize any hidden problems.

The first and main principle of winter ventilation is abandoning the slotted or micro-ventilation mode for long hours. When a window sash is left slightly ajar from the top for a long time, the walls and slopes around the opening manage to cool down, furniture is covered with cold air, and radiators begin to work at maximum capacity, trying to compensate for the constant heat loss.

The second step is the method of fast and intensive cross-ventilation, often called the shock ventilation method. Open the windows wide throughout the apartment simultaneously for just two to three minutes. During this time, the air in the rooms will be completely renewed, but massive interior items, walls, floors, and furniture will not have time to cool down, so the heat will return to the room within minutes after closing the frames.

The third stage before opening the windows is recommended to slightly turn down the thermostatic valves on the heating radiators so that the batteries do not heat the street at the time of ventilation. After completing the procedure, return the regulators to their previous position. This approach guarantees clean air in the house, the absence of drafts, the health of family members, and real savings on your finances.
