Kerosene
Kerosene is the most common home heating oil fuel in the UK. It is a colourless, thin mineral oil which has a density between 0.75 and 0.85 grams per cubic centimetre. It's extracted through the distillation of crude oil and typically boils off between 150°C and 275°C.
Kerosene has also been extracted from coal, oil shale and wood and is also known as 28-second heating oil.
