What is the crime of not turning off hot water for 24 hours in a hotel?

Most hotels will provide 24-hour hot water, even if the hot water is on 24 hours, because you are a consumer and have already paid the hotel fee.

General business hotels, express hotels or star-rated hotels have central heating water. 24-hour hot water, there is hot water as soon as the tap is turned on. Most hotels have hot water insulated water tanks (with different capacities), which are heated by equipment or injected with purchased hot water. Then there is a hot water supply system to supply water to the room. Assuming that there is no water, the hot water in the main pipe and branch pipes will get cold. We designed the return pipe at the beginning of the design, and installed an automatic backwater device during the installation. When the water temperature drops to a certain temperature (artificially set), the automatic backwater system will start, and the cooling water in the pipeline will be sent back to the heat preservation water tank to form a circulation, thus ensuring that the pipeline is always full of hot water, and the hot water will be discharged when the faucet is turned on, which also avoids the problem.
