Kentucky Boiler Practice Exam

Which boiler type is specifically defined as a storage vessel for hot water?

1. Hot Water Heating Boiler

2. Heating Boiler

3. Hot Water Storage Tank

4. Heat Recovery Boiler

The correct answer is: Hot Water Storage Tank

The correct choice is identified as a storage vessel for hot water, which is precisely what a hot water storage tank does. This type of boiler is designed specifically for the purpose of storing and supplying hot water, making it distinct from other types of boilers that may produce hot water as a byproduct of heating or serve more complex functions. A hot water storage tank maintains a reserve of heated water, allowing for immediate availability for use in various applications like domestic hot water supply or heating systems. Unlike heating boilers that may focus on heating water for circulation or process use without long-term storage, the hot water storage tank prioritizes the immediate supply of hot water by retaining it in a reservoir. In contrast, hot water heating boilers and heat recovery boilers serve different roles in heating systems. Hot water heating boilers create heat through a controlled process for distribution, while heat recovery boilers utilize waste heat from other processes to generate steam or hot water, not primarily focused on storage. Thus, the specific designation of a hot water storage tank highlights its primary function, differentiating it from other boiler types that do not emphasize storage as their main purpose.
