LOL. You forget about the spur runs to other water appliances that are
usually split off and contribute to the thermal drain. The other item
is the plumbing always goes in 90 degree angles if done by a
professional.

Cripes! My laundry tub and HW heater are more than 50' (well, maybe
40') apart the way the crow flies, let alone all the take offs in
between. I can fill my machine quarter full of cold before the hot
hits the tub. My ensuite bathroom is even worse as it is over top the
laundry room and has another 20' of pipe to go.

You would have to live in a 500 sq ft house to have less than 50'
of
copper plumbing.


Not between the laundry and the hw heater. Or do you run your
piping in a
huge loop all the way around the house to every fixture in turn? LOL
[sic].

Even with the laundry on the second floor and HW heater in the
basement, it
would have to be a pretty large house to need 50' of piping between
them.
