As stated above, the heating value increases approximately 750 Btu for each carbon added beyond methane. Tools to customize searches, view specific data sets, study detailed documentation, and access time-series data. If you already know the HHV and composition of your fuel I would apply the following: LHV = HHV - Lv_H2O (H2O_content_w + 9*H_content_w) [MJ/kg] where Lv_H2O = 2.441 MJ/kg 9 is the amount of water. A tool called chromatograph is measuring the quality of the natural gas and is able to determine the exported fossil fuels components, therefore its heating value will also be known. We don't save this data. You and your neighbor want to compare the price of the The higher the heating value, the more energy that is available for use. See Heat of combustion for examples of calculation of gross heating values from standard heat of formation of substances. If your first bedroom is at least 120 square feet, you get to call your second bedroom a bedroom if it's at least 70 square feet with 7' on a side. 365 X .4105/.58 X $1.09 (the cost of natural gas on the Energy Label) = $282. As time goes on, people will start to recognize that the heating value of natural gas is decreasing.
