i.e is there such a thing as a A rated tumble dryer?

Yes, ours has an 'A' rated cycle.

AFAICS it does it by not heating (or if it does, just warming it a bit)
the air. So of course the drying cycle runs for ages (about 8 hours for
a load)- I do use this sometimes and this in itself isn't an issue for
me. But I wonder about the extra wear and tear on motor, bearings, belt
etc.
