We and our partners use cookies to Store and/or access information on a device. (Note that many factors affect the amount of energy a household actually uses for heating, and fuel heat content may vary among locations and suppliers.). When water vapor is the product, it is called the lower (or net) heating value (LHV). The average gross heating value of natural gas is approximately 1,020 British thermal units per standard cubic foot (Btu/scf), usually varying from 950 to 1,050 Btu/scf. PDF Methodology for Thermal Efficiency and Energy Input Calculations and Higher Heating Values mean that more energy can be extracted from a given quantity of natural gas, and this usually results in a higher price for the gas. See Heat of combustion for examples of calculation of gross heating values from standard heat of formation of substances. Natural gas has a high heating value, which makes it an efficient fuel for home heating and other uses. 1 gallon of heating oil (with sulfur content at 15 to 500 parts per million) = 138,500 Btu. Biodiesel, renewable diesel, and other biofuels. The problem is that burning fossil fuels also releases harmful gases into the atmosphere, such as carbon dioxide and sulphur dioxide. This calculator is designed to calculate the following for natural gas and other combustible gases : The Gross Calorific Value is called also: Higher Calorific Value HCV, Gross Calorific Value GCV, Higher Heating Value HHV.
