Answer 1

Unlike your home hot water heater, hotels have one giant hot water heater for the entire building – not just for guests, but also for the kitchens, laundry facilities etc. And when you’re talking about a boiler for a hotel, you’re talking thousands of liters and massive amounts of BTUs. No single person or use, even if they left the water on continuously would even put a dent in the supply from one of these things.
