Which heating oil do I need?
There are two types of domestic heating oil: gas oil (aka 35-second oil or red diesel) and kerosene (aka 28-second burning oil). Although kerosene is by far the most common form of heating oil, the type you require depends on the system installed in your home, so it is always important to consult the labels on your oil boiler or tank.
If you have the option of using either fuel type, kerosene is preferable, as it is cleaner and more economical. You can even buy premium kerosene, which contains additives that make it burn more efficiently.
