Kentucky Boiler Practice Exam

What type of boiler supplies hot water without exceeding 160 psig?

1. Hot Water Storage Tank

2. Heating Boiler

3. High Pressure/Temperature Water Boiler

4. Hot Water Supply Boiler

The correct answer is: Heating Boiler

The correct answer, a heating boiler, is defined by its primary function of providing hot water for space heating without exceeding specific pressure limits. In many jurisdictions, including Kentucky, heating boilers are designed to operate within certain pressures, typically not exceeding 160 psig, to ensure safety and compliance with regulations. This type of boiler focuses on heat transfer for residential and commercial heating applications. It is critical for maintaining safety given the potential hazards of high-pressure systems. Additionally, the operation of heating boilers is traditionally designed for lower temperatures, which are suitable for heating purposes without the risks associated with higher pressure systems. In contrast, options like a hot water storage tank and a hot water supply boiler generally do not classify as heating boilers in the same regulatory framework, as their primary purpose may not be space heating but rather storage and supply of hot water for use in plumbing demands. A high pressure/temperature water boiler is explicitly designed to operate above 160 psig, which would disqualify it from being categorized as a heating boiler under discussed conditions.
