The thought of how much it would cost to power a floor fan during the energy price crisis can be enough to send anyone into a cold sweat.
However, advice from moneytransfers.com on how to cost-effectively cool your home during the heat wave will put your mind at ease.
Research has shown that the average 110 watt floor fan consumes 2p per hour, or 40p per day if it is on for 20 hours.
This would add just £12 a month to your bill.

An air conditioning unit is the most expensive way to beat the heat. It costs 23p per hour, or £4.60 per day.
This will hit you with a utility bill that is £138 higher than usual.
Ceiling fans are not common in the UK, but they are extremely economical, consuming just 6 cents per day or £1.80 in energy per month.
If you don’t have a fan, you can keep your home cool by being tactical about how you use your windows.
Open your windows and keep blinds open in the morning and evening when it’s cool (also keep the windows open all night if it’s safe) and keep out the warm air and sunlight during the heat of the day.
A temperature of 40.3C (104.5F) was recorded in the Lincolnshire village of Coningsby on Tuesday – a new all-time British record.
