In my house we've just got a really old radiant strip heater on the bathroom wall. A bit like this but wall mounted:

It works OK but I get a bit nervous using it as it's really old and it's easy to forget to turn off. I worry I might burn the house down one day!
Now it's getting colder in the mornings I'd love to replace it with something more modern. In-floor heating is not an option unfortunately.
What bathroom heating do you have and could recommend?
TIA for any ideas.
