If you've got UFH then these are perfect for heating the towels. But as someone else said, this will not sufficiently heat a average bathroom.
Jacket boiled or mashed?
Be aware this is tiny as you lose 4cm on each side for the vertical bars so you have about a foot for towels.
Good price but unless your Bathroom is the size of a shoebox this will not heat the room. I've found the BTU very low on Chrome Towel Rails unless you buy a massive one. White ones is a rate comparable with normal Radiators.
Picked a couple up yesterday, nice little rads for the bathroom/kitchen
