As the UK braces for another heatwave, with temperatures expected to reach approximately 35°C this week, households are seeking simple ways to stay cool indoors. While opening windows during the coolest parts of the day, using fans, and taking cool showers are common strategies, experts highlight a crucial step that can also reduce energy bills: unplugging heat-generating appliances.
Why Unplugging Matters
According to specialists at Ideal Home, certain appliances emit residual heat when plugged in, even when not in active use. Katie Lillywhite, appliance specialist at AO.com, explains: "Many people underestimate how much heat everyday electronics generate, even in standby mode. Smart TVs, games consoles and streaming boxes continually draw power and release low-level heat which can subtly raise room temperature when combined with other appliances." Spending a few minutes unplugging these devices can keep your living space cooler and save money.
Five Appliances to Unplug During a Heatwave
Air Fryers and Countertop Appliances
Worktop appliances, regardless of size, produce residual heat. The kitchen is already one of the warmest rooms due to ovens and washing machines. Lillywhite advises: "Start with smaller worktop appliances, like microwaves, kettles, toasters and coffee machines. Some more modern varieties feature digital displays which can generate more heat alongside internal components. Switching them off at the outlet when they're not in use can keep the space cooler." Air fryers, in particular, are popular but should be unplugged when not in use.
Tumble Dryers
With warm weather ideal for line-drying laundry, there is no need to use a tumble dryer. These appliances generate significant heat, making your home feel more stifling. Line-drying not only keeps the house cooler but also cuts costs, and clothes, sheets, and towels come away smelling fresh.
Games Consoles and Electronics
Any electronics left on standby, from games consoles to televisions, produce heat. Lillywhite notes that many people underestimate this effect. Unplugging these devices when not in use can prevent your living room from feeling unbearably warm.
Chargers
Phone and laptop chargers generate surprisingly intense heat when plugged in, even when not charging. They are often hot to the touch. During a heatwave, avoid leaving devices on charge for extended periods unnecessarily. This saves energy and reduces heat output.
Lights
Light bulbs, especially older incandescent or halogen types, emit considerable heat and waste energy if left on during daylight hours. With abundant natural light, there is little reason to have lights on. Lillywhite recommends: "Be sure to keep lights switched off as much as possible throughout the day and consider swapping incandescent or halogen bulbs for LEDs."
Additional Tips
Beyond unplugging, simple habits like opening windows only when it's cooler outside, using fans strategically, and taking cool showers can help. By unplugging these five appliances, households can create a more comfortable indoor environment and potentially lower their energy bills during the heatwave.
