For customers who have not used gas appliances before, sometimes the connections needed for the paella gas burners can be a little confusing. We supply gas burners that work with 3 different types of gas. Natural Gas, Propane & Butane. Natural Gas, or mains gas, if what is piped to millions of homes and businesses across the UK. Gas burners that use this connection are primarily for restaurants and professional kitchens, so we will not be covering these here.
The are two types of gas are in LPG gas bottles. They are Propane & Butane. They are characterised by different colour bottles and confusingly use different gas connections. All our gas burners will work with either Propane or Butane. If this is your first bottled gas appliance or you would like to know about the differences between the two differnet types of LPG, then see below, otherwise select the appropiate regulator for your cylinder.

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 (chemical formula C3H8) is a lighter gas than Butane C4H10. A given quantity of Butane will burn hotter than Propane but in fact, Propane regulators release the gas at a higher rate to compensate, so in practise, the gas burner will produce the same heat output.
So Butane must be better then? If only life were so simple. Inconveniently as butane has a higher temperature boiling point and therefore doesn’t work well at low temperatures. Butane evaporates (cooks) at + 5°C, whilst Propane evaporates at - 44°C. We use the vapor that comes from the gas cylinder, which is the gas that flows through the regulator. When too cool it stays as a liquid and the gas pressure drops. That means a butane gas cylinder will produce lower pressure once the bottle temperature drops below 10 °C. Also, all gas bottles get colder as you draw gas and the higher the rate you use gas, the colder the bottle gets. So use Butane too fast in cool temperatures and the gas pressure can drop significantly. With the much lower boiling point of Propane, this problem does not exist and bottles stored outside can be used all year round.
Gas bottles come in a variety of different sizes and are colour coded for the type of gas. Generally, in the UK, Butane is in Blue bottles and Propane in Red cylinders. The Butane bottles use a clip-on regulator with a standard internal valve size of 21mm and Propane bottles use red bottles with a screw-on regulator that needs to be tightened with a spanner. Some years ago a new format for propane was introduced called Patio Gas. This is in green bottles and uses a 27mm clip-on regulator. That means that it is not possible to connect to a propane bottle using a butane regulator or vice versa.
So to conclude, if this is your first gas bottle. Patio gas will be the best to choose as it uses an easy clip-on style regulator and works well at all air temperatures.
