A vaporstat is sensitive to what type of pressure?

A vaporstat is a device that primarily regulates and monitors the pressure of vapor in a steam heating system. It is designed to respond to changes in gas pressure, specifically the pressure of steam as it moves through the system. When the pressure reaches a set point, the vaporstat can trigger actions such as turning off a boiler or starting a pump to maintain efficient operation.

The sensitivity to gas pressure is crucial because steam is a gas, and the function of the vaporstat is directly related to the conditions within the steam system. It ensures that the system operates safely and efficiently, preventing issues that could arise from excessive pressure or improper steam flow. Therefore, understanding the role of gas pressure in a vaporstat's function is essential for anyone working with steam heating systems.
