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.

Alternatives to fans

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!)
