Then perhaps you can explain to me while during the summer (expect at
night) when I turn on the cold water I get warm and then HOT water? I
have to let it run for over a minute just to get cool water. My
neighbors that don't had direct shade on their roofs from trees have
the same problem. A friend of mine that had his house re-plumbed (so
his pipes are now in his attic) has the *same* problem.

Let me try to explain this so even you could understand it.

Let's assume the following temps to be true:
Wall temp ~80°
Attic temp (daytime) ~120°
Outside temp (daytime) ~80°
Water Heater Temp ~140°
Ground temp ~60°

When cold water is first called for during the day you get 80°(From
the wall area pipes) then 120° (From the attic pipes) then 80° (from
the outside pipes) and finally 60° (from the ground pipes).

See how simple that was?

Now at night the temps in the attic and outside will be cooler. Plug
those values into the above explanation and see how it changes.

I know that's a lot of information for you to comprehend but give it a
try.
