Does Heating Oil Freeze?

Important Info for the Winter Months

heating oil Dutchess County, NY Having an outdoor heating oil tank in the Hudson Valley means it’s vulnerable to the extreme weather conditions we experience during our four seasons. Now that winter is here, you need to worry about how cold it gets. Especially if you have an outdoor tank, you may wonder if heating oil freezes. Let’s take a closer look at the answer to that question and what you can do about it.

Does heating oil freeze? Yes. When heating oil falls below a certain temperature it gels. That means it freezes into a thick, sludge. However, it never becomes solid like ice. This gelling happens at around 16 degrees Fahrenheit and has an effect on several components of your heating system.

Heating oil gelling affects the following components of your heating system in these ways:

Can I Prevent My Heating Oil from Freezing?

There are steps you can take at your Hudson Valley home to protect your heating oil from freezing.

Why is a Full Heating Oil Tank Best?

There are a couple reasons why you should keep your heating oil tank full. In an emptier tank, debris can clog your oil filters. Clogged oil filters reduce the efficiency of your heating system and can even cause it to fail altogether. Both of those scenarios will cost you more money in energy and/or repair costs. An emptier tank is also more susceptible to condensation. The water formed by condensation forms an ideal environment for bacteria to build up and create heating oil sludge in your tank. If that sludge gets into your filters, it will decrease your system’s efficiency or cause it to fail. Condensation can also cause rust, and that rust can cause your heating system to fail. A fuller tank is also less susceptible to freezing or gelling, because the more heating oil in your tank the longer it takes to freeze.

How full is full enough? Try to keep your tank at least half full (though fuller is better) all year long.
