Keep your propane tank from freezing by insulating it, using a heating blanket, and maintaining a steady gas flow.

Propane tanks can freeze when temperatures drop, causing pressure drops and fuel flow issues. Freezing happens because propane vaporizes inside the tank, cooling the metal and creating ice. Proper insulation, heat sources, and consistent gas use prevent this problem and keep your tank working efficiently.

Insulate the tank

• Wrap the tank with an approved propane tank insulation blanket
• Use foam board or thermal blankets for temporary protection
• Avoid plastic wraps that trap moisture and cause corrosion

Use a propane tank heater

• Install a thermostatically controlled heating blanket
• Choose a heater rated for your tank size and outdoor use
• Plug into a GFCI outlet for safety

Maintain steady gas flow

• Keep appliances running at a moderate, consistent rate
• Avoid turning off and on frequently, which causes pressure swings
• Check for leaks or blockages that reduce flow

Store tank properly

• Place tank on a stable, elevated surface away from snow
• Keep it in a ventilated, covered area
• Avoid enclosed spaces like sheds or garages

Monitor tank pressure

• Use a pressure gauge to check for drops
• Refill before tank gets too low in cold weather
• Consider dual tanks for backup
