As temperatures are set to spike to 34C in parts of the UK this week, appliance specialists at AO.com have identified five household gadgets that generate significant residual heat when left plugged in. Unplugging them, they say, can make homes feel more bearable – and cut energy bills.
The warning comes as Wales braces for highs of around 30C, with experts at Ideal Home urging residents to take a few minutes to walk around their homes and unplug devices that are not in use.
“Brits urged to unplug five heat-generating appliances as temperatures hit 34C.”
“Start with smaller worktop appliances, like microwaves, kettles, toasters and coffee machines,” said Katie Lillywhite, an appliance specialist at AO.com. “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.”
The kitchen is already one of the warmest rooms in any home due to ovens and washing machines, so removing residual heat from countertop appliances can make a real difference.
Beyond the kitchen, chargers for phones and laptops are a hidden culprit. Heat radiates from chargers when they are plugged in, often leaving them hot to the touch. Experts recommend avoiding leaving devices on charge for longer periods than necessary, especially during hot weather.
Electronics left on standby are also a problem. “Many people underestimate how much heat everyday electronics generate, even in standby mode,” Lillywhite said. “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.” And with light bulbs generating significant heat when left on for long periods, switching to LED bulbs or turning them off can also help.
In Wales, where good weather has arrived, another simple step is to ditch the tumble dryer. The weather is warm enough to hang laundry outside to air dry, which not only keeps the home cooler but also leaves clothes smelling fresh and cuts costs.
While the advice is squarely aimed at comfort and savings, the cumulative effect could be significant as the UK enters its third heatwave. With temperatures reaching 34C in some areas, every degree cooler indoors can make a difference.
Lillywhite’s message is clear: unplug when not in use. It may not sound obvious, but it could be the simplest way to beat the heat.
