In the context of the ASME Boiler and Pressure Vessel Code (BPVC), a "boiler" is accurately defined as a vessel where liquid is heated to generate steam or hot water. This definition encompasses the primary function of a boiler, which is to convert water into steam or heated water that is then used for various applications such as power generation, heating, and industrial processes.

Understanding this definition is crucial because it clarifies the role of boilers in thermal systems and outlines the safety and design standards established by ASME. The BPVC includes specific guidelines and requirements to ensure the safe operation of boilers, addressing aspects such as design, materials, fabrication, testing, and inspection.

The other choices focus on different concepts that do not align with the definition of a boiler. While a storage unit for raw materials may refer to silos or tanks used in industrial processes, it does not involve the heating or steam generation aspect central to a boiler's function. Similarly, a design code for HVAC systems pertains to requirements for heating, ventilation, and air conditioning systems, and heat exchangers serve a different function by transferring heat between two fluids, rather than generating steam or hot water in the way a boiler does. Therefore, A represents the correct understanding of what constitutes
