...than using a tumble dryer, cost-wise?
I'd like to reduce our tumble dryer usage but need something to replace it so I can get clothes dry over night.
In your experiences would you think a heated airer is a good option?
Or that Dry:Soon Drying Pod thing?
It'll only be for cotton items I need to dry overnight, nothing bulky like jeans and having trouble finding clear guidance online.
The heated airers seem to be cheaper to run but if you have to use them for longer then maybe not?? 
This thread is quite old now so some of the suggestions may be out of date, but if you’ve landed here looking for product recommendations, we’ve recently updated our guide to the best heated airers with lots of options, as tried and tested by Mumsnet users and editors. We hope you find it useful.
