Is it likely to get any hotter than the 80°C of many traditional
radiators or wet towel rails?

Well that's what I thought too.
The whole story is...
The bathroom currently has a smallish towel radiator that is part of the
central heating system (combi boiler). It is mounted far closer to the
floor than 600mm, and the pipes run vertically from the floor directly
to the rad.
Obviously, in summer when the heating is not on, then the towel rad will
not get hot.
I know I can convert this rad to operation with an electrical element
too (a little plumbing I don't fancy doing), but I don't want to get
into a situation where the element fails and I have to remove the
plumbed-in rad just to change said element. Changing an element on an
all-electric rad is simpler.
So, for simplicity, I was just going to remove current plumbed-in rad
and cap off the pipes, and then install this electric one.
The house is going to be a rental property v.soon.
I'm not sure why you can't fit an element after closing the 2 valves on the current towel rail.
The current piping runs vertically from the floor, through a rad valve,
then into the rad. This is the same position as where the element needs
to go, so I'd have to add a right angle somewhere to allow the pipe to
enter the rad horizontally.
I'm not aware of any wiring regs reason to not have a low towel rail, but the item should be suitable for the task & the mfr says it isn't, though why I'm not clear. There is also the safety assesment, but I'm not sure why that would flag a hazard in this case.

What happens when the element fails? You can't just unscrew it 'cos all
the water will gush out. So you have to remove rad, invert, then
replace. This must be the same for the all-electric rads too (which may
be filled with oil).
Close valves, place tray under where the element is. Loosen element, and once rad empty, change it.

Sounds simple.
When you refill the rad, close the valves, then turn on the element, is
there a potential expansion problem?
