How close is the shower to the water heater?
If the hot water hasn't been run in a while, the hot water stored in the

AC cools off water pipes??????

It cools off *everything* in the house.

Not enough to penetrate sheetrock and cool off water pipes. I guess if

Of course it does. It just takes longer to cool the inside of walls
than to the stuff in the middle of the room. It also takes longer to
cool the middle of the room than to cool the AC ducts and the louvers
where the AC air comes out.

But with enough time, it all gets cooled. Under a day, I'll bet, and
then it stays that way until you let it get hotter in the house.

you have the capability of cooling your house to 60 degrees or so, you
might have a point. My home never gets below 78 degrees in the
summer.

I don't use AC at all but most of those who do keep it cooler than
that. Why are you using your unusual house as an example that's
supposed to apply to every eles's? In addition, if you keep your
house at 78, that's the temp inside the walls.
