Frequently Asked Questions About Cylinders and Bottled Gas
Most appliances can be used with either Butane or Propane but the cylinders use different regulators so please check what size is needed first. Propane operates at a higher pressure than Butane so it is not possible to use a butane regulator on a propane cylinder and vice versa. Propane can be used year-round due to its lower boiling point, but Butane may not give off vapour at low seasonal temperatures, typically below two degrees Celsius.
In use, the two are very similar. Propane can be used year-round due to its lower boiling point, whereas Butane may not give off vapour in low seasonal temperatures, typically below two degrees Celsius.
You should always inspect your regulator for defects and dirt ingress before connecting to any cylinder or at least annually. It is recommended that you replace your regulator every 5 years, or sooner if the manufacturer's guide recommends it. It is important that you check for defects before each connection is made.
