What gauge should be installed on a boiler?

The choice of installing both pressure and temperature gauges on a boiler is essential for optimal operation and safety concerns. Pressure gauges are critical for monitoring the system's pressure to ensure it operates within safe limits. Elevated pressure could indicate a malfunction or an unsafe condition, so constant monitoring helps mitigate potential hazards.

In addition to pressure, temperature gauges provide vital information regarding the heat levels within the boiler. This data aids in verifying that the boiler operates efficiently and within the designed thermal parameters. If the temperature is too high, it can lead to overheating, which could damage the boiler or create a dangerous situation.

Together, these gauges offer a comprehensive view of the boiler’s operating condition, helping maintain performance efficiency and safety. Having only one of these instruments—be it solely pressure, solely temperature, or just water level—would not provide enough information for effective monitoring of the system's health and functionality. The dual-use of both gauges is a standard practice in boiler operation and maintenance.
