HOT WEATHER has left many Britons spending the night in hot and stuffy rooms.
With temperatures expected to hit a staggering 43C in parts of the country this weekend, many people are scrambling to find some cool gear.
But many heatwave devices are increasing your electricity bills.
And a single tool can cost you a few bucks to use every week.
Mattress pads that spray cold water on your floor while you sleep are a great way to help you feel better on a hot night.
Some of these devices can reduce the temperature below you to a cool 13C, which can provide welcome relief from extreme heat.
You can buy one online from anywhere between £30 to £220. Remember to always shop around to get the best price.
But running one isn’t cheap.
Sarah Broomfield, electrician at Uswitch.com, said: “These appliances use around 140W of power, which would cost you 32p a night or £2.22 a week if you use it for eight hours a night.”
This means that if you use one in this way for 12 weeks in the summer, you could save £26.64 just keeping your mattress cool.
It may sound like a lot but it can add up quickly when you factor in the cost of your other heatwave equipment.
Most people don’t realize how much it costs to run a fan all night, or that the drinks fridge is one of the biggest energy users in your home.
“Water-cooled mattresses are cheaper, so it’s worth considering other options unless you’re struggling to sleep,” said Uswitch’s Sarah.
Some ways to reduce heat in winter
There are many ways to keep cool in high temperatures that should save you a lot of money.
“A cheap way is to put a bowl of ice in front of a fan, which gives you a cool breeze while you sleep,” says Sarah.
“With many fans using 40W of power on average, this only costs nine bucks for eight hours of sleep.”
Solar has also developed other ways to cool down the heat that won’t break the bank.
Using your fan properly is important. For example, there is a perfect place for fans to keep rooms cool and airy.
“Put it in a corner or on the floor where the air is cooler,” one man said in a video on the Earthtopia TikTok account.
There are also some smart tips that can help you reduce the heat.
Energy supplier Ovo said you can create a cool breeze through the house by placing a fan to point at the window.
This may seem counterintuitive, but it works by drawing in cold air from outside, and pushing out hot air.
And if you don’t want to use any equipment to cool your home, that’s fine.
You can use tin foil to protect your home from cooking heat.
All you need to do is cover your windows with reflective materials, especially those that are sensitive to the sun.
You can do this by wetting the shiny side of the foil and placing it on your windows.
The U.S. government encouraged the scam – it said that window screens like aluminum-coated cardboard reflected the heat outside.

And after the extreme heat, John Terry, Steven Gerrard and Declan Donnelly’s holiday homes have been threatened by wildfires.
