How do hotels supply enough hot water for every room?

Troy B: How do hotels supply enough hot water for every room?
In some hotels there are over three thousand rooms. What enables this huge supply of hot water? Hot water eventually goes at my house, but why not at hotels?

some time they DO run out but normally have several large commercial hot water heaters

Answer by Barkley Hound
They probably have water heaters on each floor. There is no way hot water could reach rooms in tall hotels in a reasonable time otherwise. There is a possibility that they have huge water heaters that continuously circulate the water.

Answer by jimmy7and6
most hotels have a individual water heater for each room that is hidden in a cabinet or in the ceiling between floors

Answer by DANIEL S
Most large hotels have very large steam boilers with what’s called an indirect hot water system that gives a virtually endless supply of hot water.
Some of this is based on the fact that not every room will “call” for hot water at the same time, do that, & you might run it out, but not likely.
The reason that the water is hot pretty much instantaneously is they have a hot water return system which is basically a pipe that forces cold water back to the boiler before it can escape from the hot water tap.
Hope this shed a little light on the question!!

I worked at a hotel with only 100 rooms and it had two large commericial water heaters. So, I assume, a hotel with thousands of rooms uses commerical-grade water heaters to accommodate guest rooms, in-house laundry, kitchen/restaurant, etc.
