Fuel Cost Comparison Calculator                  
  This calculator allows you to determine what the cost of other heating fuels would have to  
  be in order to provide the equal amount of heat, their equivalent price. if the equivalent price of  
  a fuel is higher then its actual price then that fuel is cheaper to heat with then the fuel  
  you entered a value for.  
 
  Any cell that is yellow can be altered.  The calculator provides some typical choices for heating  
  system efficiency for you to select from or you may enter the efficiency.  
                     
Step 1 - Enter Furnace Efficiencies  
  Furnace Efficiency   Used for  
  Default Custom Calculations  
Natural Gas  
Electric  
Propane      
Oil  
Corn Furnace 70%      
Wood      
         
Step 2 - Adjust Energy Content of Fuel if Necessary  
 
  Natural Gas BTU/Mcf   Mcf=1,000 cubic feet  
  Electric BTU/kwh  
  Propane BTU/gal  
  Oil BTU/gal  
  Corn BTU/Bushel  
  Wood BTU/cord  
 
Step 3 - Select fuel you want to compare above.
