Simple Bathroom Change to Lower Indoor Heat
An energy expert has revealed that a five-second adjustment in the bathroom can help keep homes cooler during a heatwave without increasing energy costs. Angus Struthers, managing director at boiler and air conditioning installation firm BOXT, explained that using the extractor fan while showering removes warm, humid air, preventing it from spreading throughout the home. This simple step can reduce the need for costly cooling appliances.
Struthers stated: "Even something as simple as using your extractor fan during a shower can help remove warm, humid air instead of letting it build up inside the home." He also recommended using fans alongside cooler evening air for natural ventilation, rather than running them in sealed, overheated rooms where they only circulate warm air.
Everyday Appliances That Raise Indoor Temperature
Many households unknowingly make their homes hotter by using certain appliances. Struthers highlighted four common offenders: tumble dryers, dishwashers, ovens, and gaming PCs. These devices generate significant heat, especially in smaller homes or flats, making it harder and more expensive to stay cool. He noted: "A lot of people don't realise how much extra heat everyday appliances generate during a heatwave."
For those using air conditioning units, Struthers warned that portable units can be costly if undersized for the room or improperly vented. Fans, while providing a cooling effect, do not lower room temperature and work best when paired with proper ventilation during cooler outside hours.
Prevention Is Cheaper Than Cure
Struthers emphasised that blocking heat from entering the home is the most cost-effective strategy. He advised keeping blinds closed during the hottest part of the day, opening windows strategically, and preventing heat buildup indoors. "One of the cheapest ways to keep your home cool is by stopping the heat getting in to begin with," he said.
According to BOXT, these simple measures can significantly reduce the energy needed to maintain a comfortable temperature, helping households avoid high energy bills during summer heatwaves.
