OIL OR PROPANE HEAT?

Fuel oil can generate approximately 130,000 BTU's while propane is approximately 95,000 BTU's. However, most oil boilers average about 85% efficiency at best while the gas boilers can produce an efficiency of 95% or more.

Using this data come up with the cost per BTU for both types of fuel. Find out what the cost per gallon is for oil and propane in your area and based on the assumptions above you can better determine the best cost for your dollar.

FUEL OIL: 130,000 BTU * 85% / $2.69 = 41,078 BTU's per dollar (Example cost)
PROPANE: 95,000 BTU * 95% / $1.93 = 46,762 BTU's per dollar (Example cost)
