Why does hot water come out as soon as the hotel turns on the hot water tap?

Because there are many people in the hotel, the water in the hot water pipe is used up before it gets cold, so the hot water will flow out after turning on the tap for a while. There are few people at home, and the interval between use is long. The water in the pipeline becomes cold without temperature, and it takes a long time to turn on the tap to make hot water.
