Gas & Gas Regulator Selection Guide

Our gas burners are designed to work with three different types of gas: Natural Gas, Propane, and Butane. If you are new to using gas appliances, the connections required for the paella gas burners may seem confusing. However, we are here to help.

Natural Gas, also known as mains gas, is the type of gas that is piped to millions of homes and businesses across the UK. Gas burners that use this connection are mainly used in restaurants and professional kitchens, so we will not be discussing them in this product description.

Liquefied Petroleum Gas (LPG) comes in two types: Propane and Butane. These types of gas can be distinguished by their different colored bottles and use different connections. Our gas burners will work with either Propane or Butane.

If you are new to using bottled gas appliances or are unsure about the differences between Propane and Butane, please see the information provided below. Otherwise, please select the appropriate regulator image for your cylinder.

Regulator Connections

Patio Gas and Butune Regulator Connection

Watch this short video on how to connect either a Butane gas regulator or Patio Gas regulator. The clip-on are different sizes, but they connect to the gas bottle in the same way.

Propane Bottle Regulator Connection

The Propane gas bottle regulators screw onto the bottle. The screw uses a left-handed thread which is sometimes confusing at the start.

Which is the best gas to use ?

Propane and Butane are both types of gas used for heating and cooking. Propane has a chemical formula of C3H8 and is lighter than Butane, which has a chemical formula of C4H10. Although Butane burns hotter than Propane, Propane regulators release the gas at a higher rate to produce the same heat output. However, Butane has a higher temperature boiling point and does not work well at low temperatures. Butane evaporates at +5C while Propane evaporates at -44C. This means that a Butane gas cylinder will produce lower pressure when the bottle temperature drops below 10C, making it less reliable in cool temperatures. Propane, on the other hand, has a much lower boiling point and can be used all year round.

Gas bottles come in different sizes and are color coded for the type of gas. In the UK, Butane is usually in blue bottles and Propane in red cylinders. Butane bottles use a clip-on regulator with a standard internal valve size of 21mm, while Propane bottles use a screw-on regulator that needs to be tightened with a spanner. There is also a new format for Propane called Patio Gas, which is in green bottles and uses a 27mm clip-on regulator. This means that it is not possible to connect a Butane regulator to a Propane bottle or vice versa.

In conclusion, if you are new to using gas bottles, it is best to choose Patio Gas as it uses an easy clip-on style regulator and works well at all temperatures.
