Discover the Brilliant Firefighter Trick: How to Keep Your Apartment Cool Despite the Heatwave!

Perhaps you place your fan directly in the room and let it just swirl the warm air around. Or you position it right in front of an open window and expect miracles. The problem is: This usually doesn't bring the desired effect. You don't really cool the room this way, you just create a slight circulation of the already hot air. It's like the proverbial drop in the bucket.

The Fire Department's Secret: How to Turn Your Room into a Cool Oasis

The solution is surprisingly simple and is based on a clever physical principle that is even used by the fire department for ventilating buildings. Imagine your fan not as a blower of air in, but as a puller of air out!

Instead of letting the fan blow inward, position it in front of an open window and direct it so that it expels the warm air from the room outside. Yes, you heard right: It actively blows the heat out of the apartment! This works best during the cooler evening and night hours when the outside temperatures drop.

Why This Trick Is So Brilliant

By pushing the warm room air outside, the fan creates a slight negative pressure in your room. This negative pressure is the key! It magically draws in cooler outside air through other open windows or doors. This way, your room is not only flooded with fresh air, but the stuffy heat is simultaneously transported away. It's a kind of natural ventilation system, just with a little helper.

The Perfect Setup for Maximum Freshness

For the fire brigade trick to work optimally, the correct positioning is crucial. Do not place the fan directly in the window opening. It is important that the fan is positioned so that its airflow covers the entire window frame. The rotor should be approximately at the height of the window. This way, the resulting negative pressure can work most effectively and draw significantly more warm air out of the room than if the device is placed directly in the window.

A Second Window is the Game Changer!

Very important for the success of this method: You absolutely need a second, opposite window or an open door. If only one window is open, no effective airflow can be created to draw in the fresh air. Imagine a draft system: The heat is pushed out on one side, and the coolness flows in on the other side. It works best if the second window is diagonal to the fan window.

So, forget everything you knew about fans and try this fire brigade trick! Your home will thank you.
