I have Creda Storage heaters with two dial settings each in them. Any
idea why?

Many years ago when in a shared house with storage heaters I came to the
conclusion that these very simple beasts are just too complicated for
the great unwashed. Apart from a complete inability to comprehend their
fairly simple function, nobody seems able to think more than 2 minutes
ahead and attempts to use them in the same way as an ordinary electric
heater.

One dial controls how much hot the bricks inside get overnight, one dial
controls how much hot air comes out during the day.
