It may have a design that keeps the hot water flowing even when all the
taps are turned off. That cost a little more to run, but is nice to have.

The time can also be reduced by using smaller pipe, but that can cause
other problems.

As indicated a slow leak can also be indicated.

If that water is very fast at coming up to temp, then I would suspect
the first.

Moved into a 1978 built two story home. The weird thing is we get instant
hot
water upstairs in both bathrooms. In all the homes I have lived in you
would
have to run the water a bit to get hot water. In this house the water is
very
hot instantly. Is this something that was designed in the home, or could I
have
some type of plumbing problem?
