"High pressure, high temperature water boiler" means a water boiler operating at pressures exceeding 160 pounds per square inch gauge pressure or temperatures exceeding 250 degrees Fahrenheit.3. "Heating boiler" means a steam or vapor boiler operating at pressures not exceeding 15 pounds per square inch gauge pressure, or a hot water boiler operating at pressures not exceeding 160 pounds per square inch gauge pressure or temperature not exceeding 250 degrees Fahrenheit.(b) "Unfired pressure vessel" means a vessel in which the pressure is obtained from an external source or by the application of heat from an indirect source or from a direct source, other than those vessels defined in subdivision (a) of this section.
