Will using a dehumidifier make home cheaper to heat?

applepad

Been thinking of getting a dehumidifier as we have condensation on my windows and small bits of mould in corners of rooms.

I have also read that as it will make the air in my house dryer, this will in turn make it cheaper to centrally heat my home as the air will be dry?

Can anyone confirm this?

I can't help thinking that this is one of those things that 'a man in a pub' would say!

no not really.

they are expensive to run, yes having one will help but as electric is more costly than gas, you'll maybe save a little of heating but spend more on the dehumidifier.

If you need one you need one, if you don't then getting one would not save you anything.

You'd be better off addressing the causes of the mould and condensation

We have one due to the amount of washing we have drying in the house over winter, we only need to run it a couple of hours a day but it fixed a major issue in one of the bed rooms.

I don't agree. I can run mine for 10 hours straight for less than 40p on my tariff. I wouldn't class that as expensive.

I doubt it would be economical to help heat your home though.

true, not expensive but not cost effective to save on heating whichwas the point i was trying to make...as said if you need one get one but to buy one and spend £10 a month to try and save on heating costs would be daft, if you need one because of condensation etc then they can be useful.

Heating on its own will not cure condensation. You need to insulate cold walls and window so warm moist air doesn't condense, and ventilate to get the warm moist air out of the house.

A dehumidifer can help remove the damp clammy feeling, which can help the house feel warmer and dryer even if the temperature isn't actually higher.

Nuaire Drymaster might be a better idea

We live in a 1959 semi, it's made of concrete brick, it already had cavity wall insulation when we bought it 16 years ago, we redid the upvc double glazing 14 years ago. All guttering and fascia boards have been replaced.

So I don't know what more we can do? We do need to put more insulation in the loft.

It's been raining today and you can see the wet soaked into the bricks.

We have the window open when we shower and for a bit after, same for cooking.

There is condensation on the bottom of the windows in a morning.

Do you have extractor fans in the kitchen and bathroom? If not that should definitely help.

We do have a dehumidifier and it helps clothes dry faster when they're inside on racks in wet weather. It doesn't cost much to run, £10 or £20 a month in the winter when we run it overnight most nights, but I don't think it really reduces our heating costs.
