She had found this to be a good scheme when living on her own in a
house with a very poorly insulated hot water tank, and insisted on
sticking to the strategy in a house with a double insulated hot water
tank that had an thermal time constant of three days.

She was right, in the sense that her strategy did save us about ten
dollars a year, but it meant that if I came back from hockey practice
soaked with sweat, I had a significant chance of getting stuck with a
cold shower. No amount of arguement would persuade her that my
calculation of the magnitude of the saving involved was to be relied
on.

Ah, so her plan was indeed implemented. How unfortunate.

Any chance of installing an on-demand electric water heater for when
you come home from hockey?

Or maybe a solar water preheater...? (On second thought, the capital
cost for that would be significant.)

I liked your comment so much that it's now part of my sig collection.

Thanks,

Or do like a lot of people in Florida and put their well 100 feet
from the house. You rarely have to turn the water heater on, all summer,
and you have all the hot water you can use.
