Whatever you need propane for, Superior can provide a tank size that suits your needs. Learn about our 420 lb. propane cylinders and their uses for your home or business.

420 lb propane cylinders size comparison


With a capacity of up to 372 L of propane per cylinder and our most compact permanently installed tank option, these cylinders are a go-to choice for properties with spatial limitations. While versatile for a myriad of uses ranging from water heaters, fireplaces, and other appliances to home heat, these cylinders are especially recommended when larger tanks are not feasible due to space constraints. 

420 lb. cylinders are often manifolded together, up to four in total, with the most typical amount being two or three cylinders. When two or less are used, these cylinders can be used to power back up generators, heat specific areas or power specific appliances. 

If more fuel is needed, but there is no space for a 500 gallon tank or larger, up to four 420 lb. cylinders can heat and power entire homes or businesses and multiple appliances, the same way a larger tank would. Tall and round, these propane cylinders can be easily installed right against a building wall.
Propane tanks


When a SMART* Tank™ sensor is added to one 420 lb. cylinder, it monitors the combined propane levels for all manifolded cylinders. The propane level can be viewed and tracked online through the mySUPERIOR™ app or website portal. It's designed to provide a reading for the entire connected setup, not just the individual tank with the sensor.

For example, if the tank monitoring system shows a propane level of 30%, this reflects the combined volume of all manifolded tanks, ensuring you always have a reliable and accurate understanding of your total propane supply. This integrated approach to monitoring ensures efficient fuel management and timely refills, providing peace of mind and convenience.

propane cylinder safety and prevention

Cylinder Installation: Always have your propane tank installed by a certified technician to ensure it meets local and provincial regulations, and are properly set up to ensure safety and proper performance.

Cylinder Storage: Keep the cylinder surroundings clear of debris and clutter, maintain proper clearance from buildings, and ensure the cylinder remains accessible for easy deliveries, check-ups and maintenance. Never attempt to relocate the cylinder from where the technician placed it during the installation. 

Safe Propane Levels: Keep an adequate level of propane in your propane tank to avoid rust build-up and prevent the settling of ethyl mercaptan, the odorant added to propane to help with leak detection since propane on its own is odourless.
