Yeah, I know. Another heated clothes airer thread, sorry 
I have two boys in cloth nappies (2yo - nowhere near to potty training, and an 11wo) so I have quite a high nappy turnover. Obviously they dry fastest outside, but that's increasingly no longer possible due to the weather. The heating is not really on much yet either, but even when it will be, I can see myself running out of radiator space. The nappies take a good 24 hours to dry if not right near the radiators or outside on a warm day.
Is a heated clothes airer as environmentally/financially troublesome as a dryer or hard on the nappies in some way, or worth the outlay for keeping nappies going?
TIA!
