This chart can be used to approximate the difference in cost, for a variety of heating fuels.
It will show you what you would have to spend for the same amount of heat, using other fuels.
The prices of the various fuels, obviously can change daily,
but they were fairly accurate around August 2015,
and are presented for comparisons only. Thanks.
