Howl EnduroTank 20
Built for every Howl campfire and demanding cold-weather use, the Howl EnduroTank 20 is a high-grade aluminum propane cylinder combining a true 20 lb. fuel capacity with efficient heat transfer, corrosion resistance, and a built-in fuel level gauge. Its aluminum construction transfers environmental heat into the propane more efficiently than a comparable steel tank, helping support propane vaporization and usable tank pressure as temperatures drop.
With approximately 5 gallons of propane capacity, the EnduroTank 20 provides Howl's maximum fuel reserve while adding more thermal mass than a smaller cylinder. That additional fuel volume can help the system resist temperature drop during sustained cold-weather operation.
The EnduroTank 20 weighs 13 lbs. empty and uses a standard QCC1 / Type 1 connection. It features an OPD valve, built-in fuel level gauge, rounded foot and handle, X-ray and hydrostatic testing, DOT and Transport Canada certification, and pre-purged construction that's vacuum-ready for filling.

Built for Cold-Weather Propane Performance
Propane appliances rely on more than simply having liquid fuel remaining inside the cylinder. The liquid propane must first vaporize into gas, creating the pressure required to deliver propane through the regulator and into the appliance.
That phase change requires heat. During operation, propane absorbs heat through the walls of the cylinder as liquid propane converts into vapor. As ambient temperatures fall and fuel consumption continues, the tank can become increasingly cold and its internal vapor pressure can decline.
The result can be noticeably reduced fuel delivery and smaller flames even though liquid propane remains inside the cylinder. This cold-weather pressure reduction is commonly described as tank freeze or freeze-up.
Why Aluminum?
The EnduroTank 20 addresses cold-weather operation through its aluminum cylinder construction. Aluminum has substantially higher thermal conductivity than steel, allowing environmental heat to move through the tank wall more readily.
In cold conditions, that improved heat transfer can help supply the thermal energy required for propane vaporization, allowing the tank to maintain useful vapor pressure longer before cold-related pressure reduction becomes a limiting factor.
Actual propane pressure and appliance performance will still depend on ambient temperature, fuel level, propane consumption rate, airflow, and other operating conditions. Aluminum construction does not eliminate the physical effects of extreme cold, but it can improve heat transfer into the fuel compared with steel construction.
Why the 20 lb. Capacity Helps in the Cold
The EnduroTank 20 adds another cold-weather advantage: greater fuel volume and thermal mass. With twice the propane capacity of a 10 lb. cylinder, a full EnduroTank 20 contains a larger mass of fuel that requires more energy to undergo the same temperature change.
That additional thermal mass can help the fuel resist rapid temperature drop during sustained operation. Combined with the aluminum cylinder's efficient heat transfer, the larger fuel reserve makes the EnduroTank 20 particularly well suited to high-demand and cold-weather Howl campfire setups.
Understanding Propane Tank Freeze
Propane is stored primarily as a liquid under pressure. When propane vapor leaves the cylinder to fuel your Howl or another compatible appliance, additional liquid propane must boil into vapor to replace it.
Propane's boiling point is approximately -44°F (-42°C) at atmospheric pressure, but maintaining useful vapor pressure for an operating appliance depends on the temperature of the propane and the rate at which heat can enter the cylinder.
As vaporization continuously removes heat from the propane and cylinder, cold ambient conditions can make it increasingly difficult for the surrounding environment to replace that heat. Tank pressure then falls, potentially reducing appliance output before the tank is actually empty.
Don't Insulate an Operating Propane Tank
Because propane vaporization depends on heat entering the cylinder, Howl advises against placing the tank inside a bag or other insulating enclosure during operation. Insulating the cylinder can restrict heat transfer from the surrounding environment into the tank.
Always use and store propane cylinders according to the cylinder manufacturer's instructions, the connected appliance's manual, and applicable propane safety requirements. Never use an external heat source or open flame to heat a propane cylinder.
Maximum Fuel Reserve for Howl Campfires
The EnduroTank 20 provides a true 20 lb. propane capacity, or approximately 5 gallons, for longer campfire sessions and trips where maximizing available fuel is a priority.
The tank measures 12 inches in diameter and 21.25 inches tall while weighing 13 lbs. empty. Its combination of capacity, aluminum construction, corrosion resistance, and a built-in fuel gauge makes it a practical fuel-storage option for extended overland trips, winter camping, and other demanding outdoor applications.
Built-In Fuel Level Gauge
An integrated fuel level gauge provides a convenient way to reference the tank's remaining propane level. This is particularly useful on extended trips, where knowing when to plan a refill can help prevent an unexpected interruption at camp.
