Gas Heat ESCO Practice Exam 2025 – 400 Free Practice Questions to Pass the Exam

The combustion of natural gas generates energy measured in British Thermal Units (BTUs). One cubic foot of natural gas typically yields a range between 900 and 1100 BTUs. This range reflects variations in gas composition and energy content.

Natural gas primarily consists of methane, which has a specific heat content. While factors such as pressure and temperature can influence the exact BTU output, the typical value recognized in the industry for one cubic foot of natural gas falls within the 900-1100 range. This understanding is crucial for professionals working with gas heating systems, as it helps in calculating the energy efficiency and consumption of appliances designed to utilize natural gas as a fuel source.
