 Thanks for the info, Robert.  How long have you been doing this,
 as I'm curious if there's long-term effects on the longevity of the
 system if it's cycled regularly.  I'd speculate that it would be a
 negligible effect .. as the things tend to leak or blow up often
 enough on their own.

 If cycling it each day used less power, then I wonder why this
 approach isn't promulgated more widely.  Maybe the power companies
 have enough trouble dealing with the surges of a million kettles
 being turned on each ad break .. without having to worry about the
 overloads they'd get if everyone fiddled with their hot water system.

 Jedd.
