New York Low Pressure Boiler COF Practice

Which of the following pressures indicates a low pressure boiler?

1. Above 15 psig

2. Between 10 psig and 15 psig

3. At or below 15 psig

4. Below 5 psig

The correct answer is: At or below 15 psig

A low pressure boiler is defined as a boiler that operates at pressures up to and including 15 pounds per square inch gauge (psig). Therefore, the correct choice indicates a range of pressures that meets this definition. Boilers that operate at or below this threshold are typically used in various applications, including heating systems. Recognizing this characteristic helps in understanding boiler classifications, which is essential for compliance with regulations and safety standards. Understanding the distinctions within the low pressure range assists in proper maintenance, operation, and troubleshooting of boiler systems in accordance with industry practices. The other options refer to pressures above the defined limits for low pressure, thus categorizing those conditions under different boiler classifications, which do not pertain to low pressure boilers.
