HomeResidential Heating FuelsHeating Oil All about heating oil Dating back to the 19th century, heating oil is one of the oldest fuel products used in furnaces and boilers to heat homes. Made from liquid petroleum, it is a low-viscosity fluid with a chemical structure similar to diesel and motor fuel. The majority of heating oil used in the U.S. is refined domestically. The first U.S. well that pumped oil from the ground was built in 1859 in Titusville, Pennsylvania. But the real history of heating oil in U.S. homes began in 1935 with the invention of the first forced-air furnaces that allowed the average homeowner to easily control the temperature inside their home by simply adjusting their thermostat. Oil heat is still commonly used in homes across the U.S. At Quarles, we offer our heating oil customers the reliability of local storage, competitive prices and dedicated service to keep them warm all winter.
