In home systems, the water sits a while stagnant in the
pipes until you open the valve to let some out. It takes a
bit of time for the hottest water to reach the open valve.
Many commercial buildings have a recirculating hot water
system in which a small pump circulates the water from the
hot water tank, out through the system and returns it to the
tank. City water pressure still forces it out the tap when
you open the valve, but since the water is never stagnant,
it never cools off in the pipes, and so it is always hot
when you open the tap.
