Heated clothes driers.

Marelli my daughter has her Tumble drier in the corner of her bedroom, hose goes out of the small window and she covers it with a colourful throw when she isn’t using it, it’s very light so getting it upstairs was no problem.
Are you sure you can’t find a space somewhere?

Did the one your daughter have come with a cover, BlueBelle?

I bought one for my daughter she didn’t want to offend me but said it wasn’t useful and she showed me why it literally warmed the bits of the clothes that touched the rails the rest stayed as damp as when you put them on I sent it back and got my money returned It took me ages to get my money back too
We had a Flatly many many years back and they were much better as with a lid the enclosed heat swirled around all of the clothes but these ones only warm the bits on the actual rails

Too dry to iron.

Oopsadaisy, I used to have one of those when the family were young. It did cost a lot to run, but was very good.
Apparently, to tumble dry a load costs 35p an hour. Also, having the hose stuck out of the kitchen window, letting more freezing cold air in (especially with the high winds we've been having) is making the house colder than need be!
I don't have much room either, though.

My MIL had a ‘Flatley’ back in the day, she just hung the clothes inside it and they dried, a bit stiffly though from hanging over the wooden slats. I think she used to leave it on overnight and she couldn’t have managed without it with 4 children, football kits etc.
I’m sure the modern ones are far more efficient. But I think one tumble dried load costs about 50 p, I only dry 2 loads a week, so with the cost of the airer I don’t think I would recoup the cost very quickly. Plus I don’t have the space for one and it would depend on how quickly the clothes would dry in an airer.
It would be interesting to hear how you get on though.
