You are not going to get 18kg of laundry dry using a tumble dryer for anything close to that I don’t think.

No, you’re not. Heat Pump driers seem to be just under 2kwh for a full load of cottons – maybe 8kg.

Stuff dries really well in our house anyway – we’ve got a ‘sheila maid’ type thing in the utility room and the house has a heat recovery ventilation system (and the utility has a high extract rate) so most washing dries overnight or sub 24 Hours anyway. Tumble drier generally just gets used for towels and bedding.

I wonder what the impact is on your heating costs? Evaporating water from clothes in heated house has a cooling effect – it’s not actually ‘free’ but it’s a much more complex thing to try and measure.

I don’t know about their methodology but this https://thriftyparent.co.uk/home-household/cheapest-way-to-dry-clothes-indoors/ reckons dehumidifier much more expensive.

My 2peneth.

We had a condenser in an unheated garage and it created lots of condensation.

We now have a relatively cheap vented one (in the garage still).

Isnt a dehumidifier just a condensing tumble drier that’s trying to dry your whole house? Technology is the same but it’s going to be slower and more expensive to run.

The other benefit of a dehumidifier is that it helps rids the house of moisture from bathrooms/cooking etc which we find particularly useful as we have a daughter that seems to suffer a bit with chest infections when the damper, cooler months set in and she certainly seems better with one in the house.

If it’s going in the garage get a second/ex display model of whatever ilk, massive discount, well worth keeping an eye out , we got a tumble dryer ,tiny dent in front panel( I couldn’t see it) half price ! Looking for a washing machine for utility room, salesman says ‘what you looking for sir?’ I say ‘one like that’ as man in brown coat is shifting one in shop, he says if you’ll take it as seen no box just instructions it’s yours 30% of marked price. Result.

We have done that once – a built-in washer-drier at our old house bought for a massive discount as it had a big dent in the side of it. But it’s built-in FFS!!! I was very happy.

We have a Bosch heat pump. Our electricity bill is about £200/year lower than with the vented one

And what about your gas bill. How much has that gone up?

According to the manufacturers, Meaco, it costs about 15 pence an hour to run a similar product. Like the heated airer most people leave it on overnight for 8 hours to dry a load of washing. This works out at £1.20 per load, quite a lot more than the other two methods mentioned.

15p an hour would need a machine to consume 1200w when running. Ours uses half that in max turbo mode. Normal laundry mode used 500W. Also they say ‘most people leave it on overnight for 8 hours to dry a load of washing’ – for ‘most’ I suggest they substitute in the word ‘stupid’! Yes, if used badly I guess it would use more energy.

A heat pump one will not work in the garage. Too cold. https://www.appliancesdirect.co.uk/content/tumble-dryers-buying-guide

It hasn’t changed. Why would it?
