Can Your Propane Freeze?

Posted: November 25, 2024

Cold weather can impact your propane tanks adversely.

As winter weather gets closer in Bucks and Montgomery counties, East Coast Propane customers take a lot of precautions to get ready for icy temperatures. At about this time, you start making sure there’s no water in your yard’s irrigation pipes. Maybe you even insulate your exposed plumbing to prevent icing and bursting.

Occasionally, we talk to customers who are concerned about the impact of winter on propane gas. After all, diesel and heating oil can thicken and freeze in extreme cold. Does propane have a freezing point, too?

What’s propane’s freezing point?

Propane does have a freezing point, and it’s right around negative 306°F. It would be an understatement to say that’s pretty frigid. The coldest temperature ever recorded in Pennsylvania -42°F, and that was back in 1904. The coldest temperature ever recorded on our planet was −128.6°F. That all-time low was in Antarctica in 1983. Both were way too warm to freeze propane. In fact, the boiling point of propane is roughly -44°F, right around the coldest reading in the Keystone State.

Long story short, it’s safe to say you’ll never face a scenario where the weather will make your propane freeze.

Is cold weather bad for propane?

While freezing propane isn’t a practical concern for our customers, cold weather can present genuine performance challenges for propane systems. One primary issue for propane-powered homes is tank pressure. Propane’s volume fluctuates as external temperatures rise and fall. During extended periods of freezing temperatures, the volume of liquid propane in your tank can significantly decrease. This contraction in the room it occupies can lead to a drop in pressure. In extreme cases, that could prevent propane from reaching your gas burner.

How can you prevent pressure issues with your propane tank?

Here are some ways to prevent a low-pressure problem with your home’s propane tank:

1. Keep your home’s propane tank above 30%. Tank pressure can become a problem when there’s more empty space in your tank. Avoiding low propane levels will prevent this.
2. Optimize propane usage with your thermostat. Lower the temperature setting when you’re asleep or away to help maintain tank levels above 30% and reduce your winter energy costs—a win-win!
3. Clear snow from your propane tank promptly. This allows sunlight to reach the tank, helping to maintain its warmth.
