What is the definition of a Hot Water Storage Tank?

1. It is a pressurized vessel containing steam

2. It is used for storing hot water without pressure

3. It is an unfired pressure vessel

4. It is used for external hot water supply

The correct answer is: It is an unfired pressure vessel

A Hot Water Storage Tank is defined as an unfired pressure vessel that is designed to store hot water. This type of tank typically operates at atmospheric pressure and does not involve a heating process that would generate steam, which distinguishes it from pressurized vessels containing steam. The function of a hot water storage tank is to hold water at a high temperature for later use, such as for showers, heating systems, or other applications where readily available hot water is needed. This definition emphasizes that the tank itself does not generate pressure in the way that a boiler would when it heats water to produce steam. Understanding the role of hot water storage tanks is essential for efficient heating system design and ensuring the safety and effectiveness of hot water applications in various settings.
