What significant advantage is there to wasting hot water
going down the drain? A tank type hot water heater is
going to keep the water hot, close to it's target temp,
regardless of whether you draw water or not. That idea
is like opening windows in winter so the furnace will run
to keep the house warm..... If you want to do something
to increase the amount of hot water that you'd have
available after the power goes off, then turn up the temp
on the water heater. Also, if it's a basic gas water heater,
they run without power. The power vented types or electric
ones obviously need power.


If the water heater has electric ignition, then a power failure can
switch it to pilot light mode. It depends on the exact technology in
the heater whether it depends on wall power.

The new one we had installed 5-6 years ago had a thermocouple to
power their thermostat and pizeroelectric effect to ignite so they
click. That made the heater immune to power losses.

Of course it sat next to the sump that had an electric pump. ;^)
