All I was trying to say was that the word "hot" in the phrase "hot
water heater" is redundant. You don't heat hot water, you heat cold
water. So saying hot water heater is saying it over again another time
after you've said it once. About the only place where I know there are
such things as "hot water heaters" would be in the industrial world of
superheaters, for instance. Maybe, in the application of heating an
engine above its' ambient (at that instant) temperature you'd want to
heat water that was already hot -- but then you get to the point where
you need to define "hot" by specifying the number of degrees a
thermometer would show before heating and describe said reading as
"hot", and the result would be "hotter" water.
As for preheating an engine, yup, I understand what you're saying. I
can show you dyno runs on my motor at room temp and at 185 degrees --
about 5% more hp at the higher temp. We pre-warm the motor before runs.
As for a timer on the water heater at the house -- yeah, have one, and
have taken other measures in that part of the appliance world, too,
like putting the water heater directly below the bathroom/kitchen
faucets, so the piping run to the spigot is short -- hot water arrives
quickly, and without appreciable cooling as it is on the way there.
