New York Low Pressure Boiler COF Practice

Which type of boiler typically operates at low pressure?

1. Steam boiler

2. Hot water boiler

3. High efficiency boiler

4. Locomotive boiler

The correct answer is: Hot water boiler

Hot water boilers are designed to operate at lower pressures compared to other boiler types. They typically function in residential and commercial heating applications, providing heated water for space heating and domestic hot water needs. The operational pressure in hot water boilers usually remains well below 30 psi, aligning with the definition of low-pressure systems. In contrast, steam boilers often operate at higher pressures to produce steam for heating, industrial processes, or power generation. High efficiency boilers can also operate under varying pressures but are not inherently classified as low-pressure systems. Locomotive boilers, on the other hand, tend to operate under higher pressures to generate steam for the propulsion of trains. Thus, hot water boilers are the most accurate choice for low-pressure operations within the options provided.
