Can propane gas freeze in an outdoor tank?

One of the greatest things about propane is that it keeps your family warm during the most bitter Massachusetts winters. But can temperatures dip to the point where the propane in your tank starts to seek its own shelter from the storm?

The answer is yes, in theory – but not likely in practice (at least here). As it turns out, propane turns to a liquid at -44 degrees F: f it gets that cold or colder, pressure inside the tank will drop to the point where it is too low to effectively power your propane heating equipment.

The good news It more than likely won’t get that cold here in the Bay State (for you trivia buffs, Massachusetts reached an all-time low temp of -35 on January 12, 1981, according to the National Weather Service).

Still, it pays to take some precautions if you own a propane-powered home in MA.

To avoid pressure problems during cold weather extremes:

• Order propane when your tank is no less than one-quarter full to keep positive pressure inside the tank (and prevent runouts).
• Clear snow away from your tank quickly
• Keep the regulator free of snow and ice
• Turn down the thermostat in your home – Decreasing the temperature in your house will lessen the time your system/appliance operates, permitting the pressure in the tank to build

Other extreme weather propane tips:

• Clear snow and ice from propane tank regulators, vents, piping and valves to prevent damage that could cause a gas leak.
• Remove snow and ice from appliance vents, flues and chimneys to allow the gas to vent properly.
• Place a flag, pole, or stake next to your tank that is tall enough to be seen over the expected snowfall and drifts; this will help you find the tank in heavy snow.
• Turn off the main gas supply if an appliance fails to light or if a gas leak is detected.
