I couldn't agree more. Far too many people in this country will make a big fuss over things in their houses which are of a purely convenience or cosmetic nature, yet when it comes to the electrical system they apply the ostrich-style "out of sight, out of mind" approach, and only get somebody in when something stops working or the smoke starts to rise.

check the Hot Water Cylinder temperature(good for homes with small children!),
As a matter of curiosity, what temperature would they specify for the hot water?

I seem to recall seeing somewhere that the latest codes in California (or parts of CA?) require the 'stat to be set at no more than 120 degrees. Could any of our West Coast members confirm that? I generally set 'stats to around 140 here.
