What type of boiler would a tri indicator be found on?

  1. Low pressure steam boiler

  2. High pressure steam boiler

  3. Hot water boiler

  4. Electric boiler

The correct answer is: Hot water boiler

A tri indicator is a useful device found on hot water boilers. Its primary function is to provide a clear visual representation of three vital system parameters: temperature, pressure, and water level. In a hot water boiler, maintaining the correct temperature and pressure is crucial for safe and efficient operation. The tri indicator allows operators to monitor these conditions easily and ensures that the boiler operates within safe parameters. In contrast, while other types of boilers may have various indicators and gauges, the specific combination of functions provided by the tri indicator is especially aligned with the requirements and operations of hot water boilers.
