where´s the light gone?

All of a sudden the lights of the flat went out with a pop. "The husband" being clever and a scientist told me that it was a general light failure in the city. However and as far as we could see from our balcony, everybody else has the lights on, including our next door neighnour. So, after a bit of fiddling around "the husband" figured out that it was a fuse that has blown and he promptly get us out and about. But the heater was gone.

The weather is nice enough but we´re very spoiled people who like our showers warm, so we have to figure out this pretty soon.
