Crosswater Air Towel Warmer

[kostic2000]

Hi,

The description of this towel warmer,
https://ukbathroomstore.co.uk/crosswater-air-towel-warmer-500-x-1630-brushed-brass-effect-ar50x1630f, mentions this:

"Crosswater Air rails feature innovative manufacturing technology that injects air at a very high pressure into the cross rails, this expands the cross rails to allow more hot water to circulate to generate excellent heat output."

Air at a very high pressure? What on earth does this mean? It's basically a radiator, and a hydronic one.

 

[Why Not Indeed]

I assume that's about how its manufactured, not how it operates. They inflate it with air, whilst they're making it? They're obviously very proud of this, for whatever reason.
