Fuel Comparison Calculator for Home Heating | Coalpail.c
These calculations only take into account the cost for the fuel. Pumps on boilers or fans on furnaces used to distribute the heat will increase your costs. If you have boiler or furnace and intend on replacing it with another boiler or furnaces using a different fuel these additional cost will be about the same so it's not much of a consideration.
