What is the heating value of liquid propane gas?

The heating value of liquid propane gas, often specified as the amount of heat released during combustion, is approximately 2500 BTUs per gallon. This value is significant for HVAC applications, as it helps in calculating fuel consumption and efficiency in heating systems that utilize propane as a fuel source. Propane is commonly used in residential and commercial heating applications due to its high energy content, availability, and efficiency.

Understanding this heating value is crucial for HVAC professionals, as it informs the sizing of equipment, the design of heating systems, and the estimation of fuel costs for clients. Knowing the heating value allows technicians to select appropriate appliances and burners that maximize performance while ensuring safety and regulatory compliance.

Other figures provided in the question do not reflect the correct thermal energy potential of propane gas. Therefore, recognizing 2500 BTUs as the heating value ensures accurate calculations and effective system designs in HVAC work.
