How do I prevent heating oil from freezing?

The paraffin in heating oil can freeze and clog your line, potentially preventing you from heating your home. To reduce the risk of this happening, you should insulate your tank and pipes, and have your oil filter installed indoors.

You can also purchase additives that lower the freezing temperature of heating oil, or purchase pre-treated oil. Another option is to install an electric heat sheet that warms your tank when the temperature drops, although this is relatively costly.

Having your heating oil tank installed indoors is the most effective way to prevent freezing.
