What is the primary use of a manometer in heating systems?

The primary use of a manometer in heating systems is to measure draft. A manometer functions as a device that can detect the pressure difference between two points, which is essential when evaluating the draft created by heating appliances. Proper draft is crucial for efficient combustion and the safe operation of heating systems, as it helps to ensure that exhaust gases are expelled effectively from the system, preventing the risk of dangerous gases entering living spaces.

While measuring temperature, regulating pressure, and calculating fuel flow are important aspects of heating systems, these functions are typically associated with other specialized instruments. Thermometers are used for temperature measurement, pressure regulators manage the pressure within the system, and flow meters are concerned with gauging fuel flow. Thus, the specific role of the manometer centers around measuring draft, making it an essential tool for maintaining the safety and efficiency of heating operations.
