See, it's not all about efficiency directly but questioning *if* there
were any *other* improvements that could be made that *could* have
other benefits ... like faster recovery-time or reduced scaling.

A larger (surface area) element at lower temperature may result in
slightly less scaling.

Ok.

It should not make much difference to the
recovery time though since the limit is usually the rate of heat input.

Understood ... the fact that it might make *some* difference though
(then) could be of interest to some. ;-)
