The coldest week we’ve had this month was probably the worst possible time for our hot water heater to stop working. Thankfully, due to our granny flat we have a separate hot water heater. Unthankfully, this means we have to dash over to the other building in the freezing dark every morning to shower. And I can never find my slippers.
o frabjous day! 
Sounds like the perfect time to install a solar hot water system and reduce your carbon footprint.
Yes, it might have been Mama, but fortunately with a little research and discovery of the reset button on the heater, it is fixed! Thank goodness.
