Barbeque Gas Bottles: All Questions Answered.

Man cooking on BBQ
Spring is in the air, and that means one thing – it’s finally the season to spend more time in the sun. Given the current measures around COVID-19, we know just how frustrating it can be not going out and socialising with friends and family. Although we can’t go on holiday or have social gatherings, this is the perfect time to get the barbeque fired up and enjoy a lovely meal with your household.  
If you own a gas barbeque and are confused about the type gas you need, we’ve put together a guide to identify the right BBQ gas bottle for your requirement. 


What sort of gas do I need?

Gas barbeques run on LPG (liquefied petroleum gas). 

There are two types of this gas, butane and propane. Butane is stored in blue cylinders and is ideal for camping, single burner cooking appliances and indoor portable heaters. Propane on the other hand is stored in red cylinders and predominantly a commercial heating and large appliance fuel, also ideal for heating and cooking in catering vans. Patio Gas stored in green cylinders is propane which is ideal for outdoor living appliances such as barbeques and patio heaters.  

Which Propane gas bottle do I need?
As mentioned, there are two kinds of propane gas bottles:

Patio gas 
This is specifically designed to power outdoor appliances such as BBQ’s and patio heaters and the benefit is that it is compatible with the 27mm clip on regulator. It also features a Gas Trac Indicator, which is useful for determining when your gas is running low. We sell Patio gas in 5kg and 13kg bottles. 


Propane cylinders

Propane cylinders come in a wider variety of sizes, from 3.9 kg to 47kg. However, you would require a screw in high-pressure adjustable propane regulator to attach this bottle to your barbeque. 

How do ‘clip on’ and ‘screw in’ regulators work?
A ‘clip on’ regulator is pushed onto the top of your gas bottle, whereas a ‘screw in’ regulator screws into the top of your gas bottle. The type of propane bottle you need will depend on what regulator your barbeque comes with. 

Why do you need a regulator on a gas bottle?
The gas bottle is always attached via a regulator. This performs an important safety function, as it controls the pressure at which the gas moves from the bottle to the appliance. It is important to ensure that you have the correct regulator fitted to your appliance for your chosen gas bottle. In simple terms, a green Patio gas bottle is compatible with a clip on regulator, whereas a red propane bottle will require a screw in regulator.

Which BBQ gas bottle do I need - what size?
This depends largely on how many burners your gas barbeque has. If it has between one and three, a 5kg patio gas bottle is ideal. If you’ve got a larger barbeque with four burners or more, then it’s recommended that you select a 13kg bottle. We have a handy tool: ‘Which gas bottle do I need’, that could tell you specifically which bottle would be most suitable for your barbeque.
