Btu higher or lower
WebIf not, multiply the input BTUs by the furnace’s efficiency. For example, an older furnace rated for 100,000 input BTUs at 75-percent efficiency has 75,000 output BTUs. A newer, higher-efficiency furnace might have a lower rating for input BTUs, but still put out the 75,000 output BTUs you need. Detailed Calculation Zwolinski and Wilhoit defined, in 1972, "gross" and "net" values for heats of combustion. In the gross definition the products are the most stable compounds, e.g. H 2O(l), Br 2(l), I 2(s) and H 2SO 4(l). In the net definition the products are the gases produced when the compound is burned in an open flame, e.g. H 2O(g), Br 2(g), I 2(g) and SO 2(g). In both definitions the products for C, F, Cl and N are CO 2(g), HF(g), Cl 2(g) and N 2(g), respectively.
