The earth's energy reserves of fossil fuels are becoming ever scarcer and the prices ever higher. This applies above all to the cost of oil and gas or even coal, the fossil fuels we need for heating.
Here are some tips on how you can save energy and thus money:
Ventilate several times a day (approx. 3 - 5 times) and open the windows fully.
Turn down the thermostatic valves during ventilation. With this airing, air is exchanged and walls and furniture do not cool down. The fresh air that flows in can absorb the heat from the radiators more quickly. It thus ensures a pleasant room climate. This type of ventilation also saves energy.
If you only leave the windows tilted, the room temperature is permanently lowered. Walls and furniture cool down and the radiators constantly reheat. The heat thus generated is drawn outwards by the air suction and does not remain in the room. This is especially true for radiators that are mounted below the window sill.
But the right furniture is also important. Do not place any furniture in front of the radiators. Ensure unhindered heat transport through optimal air circulation. Try not to place walls of cupboards or other large pieces of furniture against outside walls; if this is not possible, leave a space between the furniture and the wall to allow air to circulate. Curtains or drapes should also not cover the radiators; if possible, let curtains close off above the radiators.
Do not dry damp laundry in the flat, use the drying rooms provided for this purpose, even if the way there is sometimes arduous. Your heating system will try to absorb the additional moisture by further heating, and the humidity in the flat will also increase and you will have to ventilate more.
This is a simple way to save money and help conserve the earth's energy reserves.
