Energy-saving tips for the cold season

When temperatures drop, energy consumption increases – often unnecessarily. With a few simple measures, you can keep the heat in the house without sacrificing fresh air. LIMODOR shows how efficient ventilation works in winter and which technical solutions help to save energy.

Shock ventilation instead of tilt ventilation

Short, intensive airing several times a day (5-10 minutes with the window wide open) ensures the rapid exchange of stale air. It also prevents heat-radiating heating elements such as floors or radiators from cooling down too much. For physical reasons, the warm air flows towards the cold outside environment by natural convection. Permanently tilted – and often forgotten – windows, on the other hand, are real energy guzzlers.
Shock ventilation of a home is also possible with individual ventilation elements, for example in the bathroom or WC. Many ventilation control systems also have a time-controlled summer mode. Of course, shock ventilation is no substitute for protection against insects, pollen and allergens or noise. Decentralized home ventilation systems, which can also be retrofitted, are therefore an energy-saving alternative for ventilation in living areas or home offices in times of climate change and urban living spaces. They pay for themselves quickly.

Switch off the heating when ventilating

During ventilation, the heating control or the radiator should be turned down or switched off briefly to prevent unnecessary heat loss. This often happens because the heating is turned up to full power during ventilation due to the falling room temperature. Compact decentralized domestic ventilation units from LIMODOR are a convenient technical alternative. They use a heat exchanger to feed most of the energy from the extracted stale room air back into the fresh air that is drawn in. They also work continuously and do not cause draughts. Some of them can be retrofitted very easily. A core hole drilled through the wall and a power connection are all that is needed.

Cross ventilation accelerates air exchange

Make sure you use it: The ventilation effect is improved and can be achieved in a much shorter time if a draught can be created by opening several windows. However, turn down any radiators under the windows during ventilation! However, it is counterproductive if the windows are left open for too long. This is because not only does warm, stale air flow out of the room, but the draught also draws cold air into the room. Even in larger rooms, this causes very rapid cooling and therefore a high loss of energy. Draughts are also unpleasant.

Plan a fixed ventilation unit in the WC

It doesn’t always have to be a complete home ventilation system. But an efficient ventilation unit in the WC pays for itself in a short time. A toilet window, which is usually very small, hardly ensures efficient removal of odors even if it is opened for a longer period of time. At the same time, the room cools down considerably, especially in winter, due to its usually small size. This is very unpleasant for users.
Axial fans or the much more efficient single-pipe ventilation systems, a LIMODOR patent, are therefore widely used in apartments and houses. They lead the odorous air either directly through the wall or outside via a ventilation pipe, to which several devices can be connected. The extracted – small – volume of air is replaced by tempered air flowing in from the living area. This prevents frostbite on the WC.

Prevention of bathroom moisture through energy-efficient ventilation

Steam builds up quickly, especially in the bathroom, which causes unpleasant humidity after condensation. This only disappears to a limited extent by simply opening the window. In the cold season, the cooling in the room even causes particularly rapid condensation. In addition, cold in the bathroom is of course undesirable. Without technical support, such as a single-pipe ventilation system, it is not possible to achieve truly satisfactory dehumidification while retaining heat for these physical reasons.
It is important to locate the air extraction system close to the source of the moisture – in the shower area, for example. In addition, an unhindered flow of tempered air from the living area should be ensured from the direction of the bathroom door. Blind spots for the fan installation – such as behind the door or partition walls – should be avoided. Most bathroom fans have their own humidity sensors, which switch on automatically when a limit value is exceeded and prevent too much humidity from occurring in the room.

Conclusion

Correct ventilation saves energy, protects the building fabric and ensures a healthy indoor climate. Those who rely on efficient technology can perfectly combine comfort and sustainability.
