The advice to "wire across the built-in stat and add an external stat strapped to the tank" seems extremely iffy and completely contrary to current regs requiring a manually-resettable over-temperature cutout to be incorporated into the stat.
I think it would be good for an article on immersion heaters to reference this regulation.

The bit about burning smell etc, talks of checking the flexible cable and that has a link to the "Cables" article.... which only discusses wiring cables, not high temperature insulated flexes.
Sounds like we need a "Flex" article.

Yes, I reckon we still could do with lots of articles. Not sure whether flexes might be best dealt with in a separate article or the same one as fixed cables. NT 09:37, 16 June 2007 (BST)
On the basis that I've seen many dozens of installations with immersions controlled by on/off switches (or just 13A plug & socket) and none with timers, I've changed the wording of the appropriate part of this article --John Stumbles 18:02, 29 February 2008 (GMT)
