High Temperature Hot Water (HTHW) Engineer License Program: 1st Class, 2nd Class and 3rd Class

 

A High Temperature Hot Water (HTHW) Operating Engineer has job tasks that are unrelated to steam operations or steam boilers with the exception of the combustion and draft process. The differences are striking from the High-Temp Building or HTHW Boiler Room loop operations to the Hi-Temp distribution loop or campus loop piping and their mechanical room where the converters or heat exchangers are operated. High-Temperature Hot Water operations may have split job tasks HTHW Boiler NASOE License Engineerbetween High-Temp Building or HTHW Boiler Room and the Hi-Temp Distribution Loop. In both cases the Hi-Temp Distribution Loop operations is included in the HTHW License Program.

Where there is a Medium Temperature Hot Water MTHW operations, this HTHW license program is very-appropiate and applicable. Only in the LTHW (low-temperature hot water) is the HTHW license program not applicable, for LTHW applies to the Low Pressure Boiler Operator NASOE license program.

High-Temperature Hot Water Engineer 1st Class

A high pressure steam plant (boiler operating) engineer First-Class is intended for a supervisory role as a "Supervisor" in the steam plant. Having overall responsibility as a supervisor for the entire steam plant including employees and equipment.

The qualifications to sit (write) for the High-Pressure Steam Plant (Boiler Operator) Engineer 1st Class exam the individual must have 24-months of experience in a high-pressure heating plant or 2-year technical or science college degree with 6-months experience. A 2nd Class can sit for the High-Pressure Boiler Operating Engineer 1st Class exam with an accumulated 12-months of experience.

A 1st Class High-Temperature Hot Water Engineer can operate any HTHW or MTHW boiler or plant of unlimited size (MMBtu/Hr). The 1st Class HTHW Engineers license is intended for what plant personnel identifies as Chief Engineer, Assistant Chief of the Plant, or Supervisors.

Reference materials to study from, for the examination, are:

      1. High Temperature Hot Water, 1st Edition
      2. Stationary Engineering, 4th Edition, by Steingress, Frost and Walker - Chapters 4 and 11

The license certificate exam is based on what a In-Charge Supervisor (1st Class) of the Plant should be able to do such as comprehensive thinking and more specifically analysis and synthesize the the entire HTHW/MTHW plant and system conditions. Examination is a 50-Question test in a 1-1/2 hour period. The components of the exam is made up of the following:

High-Temperature Hot Water Engineer 3rd Class

The purposes of the Hi-Temp Hot Water 3rd Class Engineer's License is to provide an entry level into high temperature operations.

A HTHW engineer 3rd Class is intended for a non-supervisory role in a high-temp hot water system. A 3rd Class HTHW Engineer can operated HTHW plant under a 2nd Class or under the supervision and/or leadership of a higher-grade license. The 3rd Class HTHW Engineer license is intended for watch engineer or shift engineer (non-supervisory).

The qualifications to sit (write) for the High-Temperature Hot Water Engineer 3rd Class exam is meet the following requirements:

      1. At least 6-months experience working in a HTHW or MTHW Plant/System; or
      2. 3-months of experience working in a HTHW or MTHW Plant/System with at least 3-months experience on HP Steam Boilers; or
      3. 3-months of experience working in a HTHW or MTHW Plant/System with at least 6-months experience in HVAC; or
