Are heated airers worth it in a small student flat?

[ssd]

In Scotland, so cold damp and wet a lot of the time. Student sons room is small and he struggles with getting washing dry. I want to buy him a heated airer or dri buddy but he can't have anything too big.

Any ideas?

'17. Reasonable Care

The Tenant agrees to take reasonable care of the Let Property and any common parts, and in particular agrees to take all reasonable steps to:

keep the Let Property adequately ventilated and heated;'

I'm sure they turn it on sometime but as little as possible I think
