When using gas-powered appliances, whether for cooking, heating, or outdoor activities, selecting the correct gas regulator is critical for both safety and efficiency. The right regulator ensures that the gas flow is properly controlled, preventing accidents and optimizing appliance performance. But with various types of gas regulators available, how do you know which one to choose? In this blog post, we’ll guide you through the essential factors to consider when selecting a gas regulator for your appliance.
1. Understand Your Gas Type: Propane or Butane?
The first step in choosing the right gas regulator is determining the type of gas you're using. Most commonly, gas appliances run on either propane or butane, and the gas type will determine the regulator you need.
Propane: Propane is commonly used for outdoor appliances, including BBQs, patio heaters, and large outdoor cooking equipment. It typically requires a higher pressure to function correctly.
Butane: Butane is commonly used for indoor appliances or smaller outdoor devices. It operates at a lower pressure compared to propane, so a different regulator is needed.
Both gases also come in different bottle sizes, which will influence the choice of regulator.
2. Choosing the Right Regulator for Your Appliance
Different gas appliances have specific pressure requirements, and choosing the correct regulator is essential for safety and performance.
Boiling Rings
For appliances like boiling rings, a low-pressure regulator is typically required. These are usually used with butane gas, and a 28 mbar regulator is a common choice.
Tip: Check if your boiling ring is compatible with a 28 mbar or 37 mbar regulator, depending on the gas type and appliance specifications.
Gas BBQs
Gas BBQs typically require a 37 mbar regulator when using propane gas. This higher-pressure regulator ensures a strong and consistent flame for grilling.
Tip: If your BBQ uses butane, it may require a 28 mbar regulator instead. Always check the manufacturer's guidelines to ensure compatibility.

3. Consider the Size of Your Gas Bottle
The size of the gas bottle you're using will also impact your regulator selection. Calor Gas bottles come in various sizes, including 5kg, 13kg, and 47kg, and each may require a different regulator depending on the appliance you're using.
For small bottles (e.g., 5kg), a low-pressure regulator (28 mbar) is often suitable for smaller appliances.
For larger bottles (e.g., 13kg or 47kg), a high-pressure regulator (typically 37 mbar for propane) is needed for appliances like space heaters and blow torches.

Be sure to match your regulator to the gas bottle size and the type of appliance to avoid performance issues.
4. Check Pressure Requirements for Your Appliance
Each gas appliance has specific pressure requirements for optimal functioning. While most low-pressure appliances use a 28 mbar regulator, higher-powered outdoor appliances like BBQs or patio heaters typically require 37 mbar regulators.
Make sure to check your appliance’s manual or product specifications to ensure you are using the right pressure. Using the wrong pressure regulator can result in poor performance, inefficient gas use, or safety hazards.
5. Selecting the Right Hose for Connection
In addition to the regulator, you will need a hose that is compatible with both the gas bottle and the appliance. Make sure the hose is rated for the appropriate pressure and gas type (propane or butane).
Tip: Regularly check hoses for wear, cracks, or damage to ensure a secure and leak-free connection between your gas bottle and appliance.

Gas Regulators can also be connected via a rubber pigtail, the most common fittings on a pigtail are W20 which will thread into a M20 connection on some regulators, also a POL fitting will screw in to most propane UK gas cylinders, the most popular cylinder sizes being 19kg and 47kg capacity
The other most common pigtail fitting is Butane Nut which is 21.8mm left hand thread, which is attached to most adaptors for example 20mm, 21mm, 27 mm and Campingaz adaptors

6. Regulator Safety Features
Safety is always a priority when working with gas, so choosing a regulator with built-in safety features is highly recommended. Modern gas regulators come equipped with pressure relief valves to prevent over-pressurization, and some include built-in shutoff mechanisms in case of leaks or other hazards.
Be sure to select a UKCA or CE-marked regulator, ensuring that it complies with UK and EU safety standards.
7. Replacing and Maintaining Your Regulator
Gas regulators don’t last forever. Over time, they can wear out, or the rubber seals may deteriorate, leading to potential leaks or malfunctioning. It’s important to periodically check your regulator, hose, and connections for wear and tear. Replace any damaged components immediately to maintain safe gas flow.
Tip: Gas regulators typically last for several years, but they should be checked for signs of damage, especially before and after long periods of non-use (e.g., winter storage).
8. New Regulator Guidance: OPSO Regulators
If you’re using an older gas bottle and regulator, consider upgrading to an OPSO (Over Pressure Shut Off) regulator. New regulations are encouraging the use of OPSO regulators for greater safety. These regulators include automatic shut-off mechanisms that cut off the gas flow if the pressure becomes too high, reducing the risk of accidents.

Conclusion
Selecting the right gas regulator for your appliance involves understanding the type of gas you’re using, the pressure requirements of your appliance, and the size of your gas cylinder. Whether you're using a boiling ring, BBQ, or other outdoor appliance, matching the right regulator will ensure safe and efficient operation. Always check manufacturer recommendations for pressure settings, gas type, and bottle size, and make sure to maintain your regulators for optimal performance and safety.
