Close Curtains and Windows
British Gas advises keeping windows shut during the hottest part of the day to maintain cooler indoor temperatures. “Tempting as it might be to throw your windows open during a heatwave, leaving them shut when the day is at its hottest will keep rooms cool in summer,” the energy supplier wrote on their blog. They recommend only letting in air early or late in the day.
Create a Cooling Effect with Simple Tricks
To “really cool a room down” with a fan, place a deep dish of ice in front of it to chill the airflow. Alternatively, direct a box fan outwards through an open window during evening hours to expel warm air rather than simply circulating it inside.
Encourage Air Flow
If your aim is to cool a room with a fan, shutting off unoccupied rooms throughout the day will help maintain a cool home during summer. Opening interior doors when you open windows in the evening promotes air circulation. British Gas suggests: “A good strategy is to open windows on opposite sides of your home in the early morning or late evening when the outdoor temperature is lower. This encourages airflow by letting the warm air inside escape and be replaced by cooler air from outside. If that's not an option, for example, if you live in a flat that only has windows on one side, open internal doors and use a fan to get the air moving.”
Install Reflective Window Film
An economical and “super effective” method for maintaining a cool home is fitting reflective window film. British Gas states it can be fitted yourself and can cut heat and glare by up to 99%. Some households have even experimented with using tin foil, which they already have in their cupboards.
Make Smart Use of Extractor Fans
The experts explain: “Extractors don't just get rid of smells and steam from cooking and showering, during hot weather, they can be put to double use. Open your internal doors and leave your bathroom and kitchen extractor fans running for a while to create airflow to help remove warm air. It's best to do this after cooking or showering, which can both increase humidity and heat. Make sure to open windows and vents elsewhere so that fresh cooler air can come in to replace the warm air expelled by the extractor fan.”
Keep Yourself Cool, Too
During a heatwave, taking a lukewarm shower can help regulate your body temperature and reduce energy consumption and costs on your bills. After stepping out of the shower, opt for loose, breathable garments made from natural fabrics to help regulate body temperature. Wearing looser clothing allows air to circulate more freely, helping your body cool down even in the slightest breeze.
