How much electricity does a fan use overnight?

It’s been a hot week, and the heat doesn’t look like it’s going to be going away any time soon.

This heat means one thing. Everyone is plugging their fans in.

I myself was up in the loft this weekend hunting for the fan that makes an appearance in the house once or twice a year.

We leave the fan on overnight and it left me wondering – how much electricity am I using?

Here’s the maths

– Average fan wattage: 60

– Average time on overnight: 8 hours

– Average price per kWh: 0.28p

– Total cost to run a 60-watt fan for 8 hours overnight: £0.13p

So, at 13p per night – it’s not costing us very much whatsoever.

Whilst 13p isn’t much, that cost can add up over time especially if you’ve got multiple fans in the house.

There are a couple of other things you can do around the house to reduce the need for a fan at night:

Keep blinds and curtains shut throughout the day to reduce direct sunlight coming in
Shut internal doors
Use cotton bed sheets
Open windows
Turn off the lights (non-LED bulbs get very hot!)
