As our HW cylinder is under the house, and we'll eventually move to gas HW - what are the other options around keeping a level of heat/ventillation in the laundry cupboard? I got a new towel out this morning for my shower and it was musty and cold.

I had opened the cupboards and ran the dehumidifier by it, but that's not an elegant solution.

What are some of the options that people know of?
