pound | 1500 (.75 tons) | x | $140 / ton | = | $105.00 | Heat is measured in BTU's. One BTU is the amount of heat needed to raise one pound of water by one degree Farenheit. 18 million BTU's is about a quarter of the typical yeary heating requirement of an average home in a cold climate. In a warm climate, this figure may represent a full years heating requirement. Prices shown are conservative! |
1Note:The 'cost' results above can be adapted to any price fluctuations in your area by supplementing the latest applicable Current Fuel Price per Unit. | | 2Note: Unless a 'gravity' hot water heating-circulation system is used, all common furnace types use approximately 200 KWH of electrical energy per year to force air or pump water, which adds an additional $16 per year in electric consumption. | | 3Note: Shelled corn can be purchased at reduced prices (i.e. moldy corn, scorched corn, etc.). The BTU content of shelled corn will vary between 8,000 and 10,000 BTU/lb. and 9,000 BTUs (X 56 lbs. per Bushel) has be used in the example above. Use corn at 14-15% moisture content, or pellets at 8% moisture content supply this efficiency. Seasonally, dry shelled corn varies in price from $1.50 to $3.00 per bushel. | 4Note: Coal varies in quality, with bituminous being the most effective at 12,000 BTU/lb. Sub-bituminous coal has a heating value of 8,750 BTU/lb. and lignite coal has a heating value of 6,500 BTU/lb. Commercial grade mixtures of coal have been declining steadily in quality since the late 1960s.
