What is the normal operating pressure for a boiler?

The normal operating pressure for a boiler is typically in the range of 12 to 15 psi. This pressure range ensures efficient operation of the heating system and maintains the necessary water temperature for effective heat distribution throughout the building.

At pressures lower than this range, the boiler may struggle to distribute heat effectively, which can result in inadequate heating in the spaces served by the system. Conversely, excessively high pressure can lead to safety concerns and potential equipment damage. Therefore, the 12 to 15 psi range is balanced, providing enough pressure for optimal performance while also allowing for safe operation. Understanding this operating range is crucial for HVAC professionals to ensure that boiler systems are maintained within safe and efficient parameters.
