Questions about Gaslight and bottled gas

Frequently asked questions about cylinders and bottled gas

What's the difference between Butane and Propane?

In use the two are very similar. Propane can be used all year round due to it's very low boiling temperature whereas Butane tends to be more suitable for summer use as low winter temperatures may mean the liquid will not boil to produce vapour to burn.

Can I switch from Butane to Propane?

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 all year round due to it’s lower boiling point, Butane may not give off vapour in low seasonal temperatures, typically below two degrees Celsius.

How often should I replace my regulator?

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 five years or sooner if the manufacturer guide recommends this. It is important that you check before each connection is made though for defects.
