There still is none.
Today the plumber appeared and did some magic that got the heater burbling away again.
But then there was an exciting pop and the breaker flipped itself off.
More tweaking and it seemed to be working.
And then another pop.
Another reset. Another pop.
Something's definitely not right. The likely culprit seems to be the thermostat, so its number is just about up now.
Hopefully we will have some hot water before we lose use of our backup shower, or else things might start to get a little fragrant.
