Dehumidifier usage cost

[Deleted User]

Good afternoon,

I know this board has a wealth of members with wonderful knowledge so I hoped you could help me.

Since the temperature has dropped a lot here and the rain has arrived, I am running a Meaco dehumidifier in my daughter’s room - we get damp here and until financially we can deal with the damp proofing and get the repointing done we desperately need, the dehumidifier will help. It’s an old house (around 250 years) so nothing is cheap or quick to fix! 

The Meaco says it has a Rated Power of 180W on the label. My question is, how do I work out how much electricity it uses in 24 hours so I can budget accordingly? As a household we are very very careful and tend to stay on or under the 8KW/h mark for every 24 hour period. 

Many thanks xx

The Meaco 12L Low Energy Dehumidifier uses just 157 watts of electricity.

So a peak load would be 180*24=4.3kw per day.

In reality it will cycle on and off as needed depending on humidity. So a rough rule of thumb would be 50%. Or to be more accurate use an energy monitor plug over a 24hour period. I would guess 92p per day.... peak load would be £1.80

Hope that helps.

Simple, if you have a 180W appliance - and it is on constantly - then it will consume 24*180 or 4320Wh. This is equates to 4.32kWh or 4.32 units on your bill.

That's not how dehumidifier work as they don't keep working when that get humidity had been reached.

Our dehumidifer has a humidity level on its display - opening the window for 10-20 minutes in the morning makes it drop like a stone.

Don't forget that if it is cold and it's a compressor based dehumidifier it will run defrost cycles too when it won't be dehumidifying.

A compressor dehumidifier is able to extract some latent heat from the humidity, which will offset its running costs slightly.

My ancient Argos 'Value' unit is rated @ 250W

It consumes:- 0.114kw/H

Measured with a plug-in power meter.
