This chart is a quick way to compare your relative fuel costs.
The relative efficiencies of each fuel and boiler combination have been factored in.
Directions to compare your present energy cost:
- Find the vertical column that lists your boilers fuel (natural gas or oil).
- Move down that column until you find a cost that is closest to your fuel cost.
- Move horizontally across to see the equivalent fuel costs to your current wood waste available.
- The cost listed under your waste fuel is the dollar amount you would save burning one ton of your
wood waste (or it's value as energy based on fosil fuel cost).
