The sparky came and sorted out things a bit, shifting the stuff that didn't work off the power circuit that was out to one that did work. A few minutes after everything was swapped another bloke came and replaced the fuse in the transformer, which is still working, apparently it blow due to some wet fuse boxes on houses shorting out - they just needed extra time to dry out.
So last night, after 8:30pm, we had lights and the hot water tank was heating water - finally had hot showers at home!
