So, it's 3am and we're running every hot tap in the house...

[panik]

Oh yes indeedy, damn stove played the same damn trick on us the old one would occasionally and, though thoroughly damped down as low as it damn well goes, churned out so much hot water the tanks boiled and the pump started screaming like a prize sow in labour. Only one option when that happens and that's to get up and drain off the hot water - scaldingly hot it was too, almost boiling. Made me weep to throw it away rather than magic it into a soothing bath but it was 3am, you know?

Never really got back to sleep.

Shattered.

Damn.
