What is the heating value of natural gas (Methane)?

The heating value of natural gas, primarily methane, is typically around 1,000 British thermal units (BTUs) per cubic foot at standard conditions. This measurement reflects the amount of energy released when a certain volume of natural gas is combusted completely.

While other values listed may represent different conditions, specific gas mixes, or higher heating values under other contexts, the standard heating value for methane itself, under typical conditions, is widely accepted to be about 1,000 BTUs per cubic foot. Understanding this value is crucial in applications of gas heating systems where efficiency and energy content calculations are involved. It guides HVAC professionals in performing accurate calculations for system design, calculating fuel needs, and estimating operational costs for heating systems employing natural gas.
