Frigid weather has arrived on the Eastern Shore, and many Callahan’s Gas customers have been speaking to us about how low temperatures can impact the reliability of their propane systems. One of their questions is whether propane can freeze.
This is a reasonable question. After all, with water’s freezing point of 32°F, it’s not unusual to see frozen puddles outside after a cold night. Diesel fuel starts to thicken or “gel” at around 15°F.
You don’t need to worry about propane freezing in the same way as water or diesel, but winter weather can negatively impact your propane system. In this article, we’ll discuss the issues your propane equipment might face and how you can prevent them before they happen.
Technically, propane does have a freezing point — roughly -306.4°F. For reference, the lowest temperature ever recorded in Maryland was over a century ago, and it was -40°F. That is warmer than propane’s boiling point (-43.6°). Looking even further, the coldest temperature ever recorded in the U.S. was -80° (Fairbanks, AK, 1971), and the lowest-ever reading anywhere in the world was −128.6 °F (Antarctica, 1983).
All this is to say that propane might have the capability of freezing, but the weather conditions required to make that happen will not occur during the winter in Maryland (or, for that matter, on Earth).
Even though winter’s chilly temps won’t freeze your propane, they can still hinder how well your gas equipment runs.
One concern in the winter is ice causing your system regulator to freeze. Propane regulators are like the barrier between the high pressure in your tank and the lower pressure needed to deliver propane gas to home appliances or equipment. If this device freezes, the flow of fuel to your home can be impeded.
Another significant issue is that propane’s volume contracts in the cold. So, when it gets really cold for a long time, the propane in your tank takes up less space. If the volume drops too much, you might end up with low-pressure problems in the tank.
Here are a few simple steps you can take to limit negative effects on your home’s propane system in the winter.
