What Is The GC Number On A Boiler?

If you’ve ever dealt with a boiler or gas appliance, or found yourself looking for a spare boiler part, you might have come across the term GC Number. But what exactly is it, and why is it important?

In this article, we’ll dive into the details of the GC Number, shedding light on its significance and how it helps in the identification and servicing of gas appliances.

Introduction To The GC Number

The GC Number, which stands for Gas Council Number, is a unique identification system used for gas appliances, including boilers.

This system was developed by British Gas in collaboration with boiler manufacturers and suppliers to streamline the process of identifying different types of gas appliances.

Think of it as a unique fingerprint for each appliance that tells you not just what it is, but who made it and the specific model.

Breaking Down The GC Number – What Does It Mean?

The GC Number is composed of seven digits formatted as 00-000-00. Each section of this number provides specific information:

• First Digit (00-000-00): This digit signifies the main type of appliance. For instance, a ‘4’ typically denotes central heating boilers.
• Second Digit (00-000-00): This digit specifies the type of appliance within the main category. For example, a ‘7’ might indicate a combination boiler.
• Middle Three Digits (00-000-00): These three digits identify the manufacturer. Every manufacturer has a unique set of numbers.
• Last Two Digits (00-000-00): These digits represent the model or sub-range of the appliance.

Why Is The GC Number Important?

The GC Number is essential for several reasons. Firstly, it helps in accurately identifying a specific gas appliance, which is crucial when ordering parts, performing maintenance, or troubleshooting issues. If a technician knows the GC Number, they can quickly determine the exact make and model, ensuring they have the right parts and information for the job.

Secondly, the GC Number facilitates better communication between manufacturers, suppliers, and service engineers.

With a standardised system, there’s less room for error when discussing or documenting different appliances. This standardisation also helps in maintaining safety standards, as specific models might have particular servicing needs or known issues that technicians need to be aware of.

Examples Of GC Numbers And Appliance Types

To give you a clearer picture, here are some examples of appliance types based on the first two digits of the GC Number:

• 11 = Cooker Grill: This might be the code for a kitchen appliance like a cooker with a grill function.
• 31 = Gas Fire: Represents gas-fired heating units.
• 37 = Back Boiler Unit: Indicates a boiler that fits behind a fireplace.
• 41 = Central Heating Boiler: A standard central heating boiler.
• 47 = Combination Boiler (Combi): A combi boiler that provides both heating and hot water.
• 51 = Instantaneous Water Heater: Heaters that provide hot water on demand.
• 52 = Multi-point Water Heater: Heaters that supply water to multiple outlets.

Finding The GC Number On Your Boiler

Locating the GC Number on your boiler is usually straightforward. It is typically found on the data plate, which is a label or plaque affixed to the boiler. This plate includes various pieces of information about the appliance, such as the serial number, model number, and, of course, the GC Number.

If you can’t find it, your boiler’s user manual should have this information. If all else fails, contacting the manufacturer or a certified technician will help you identify it.

Conclusion

In summary, the GC Number is an important part in the world of gas appliances, particularly boilers. It simplifies the identification process, ensures accurate maintenance and servicing, and helps uphold safety standards.

Whether you’re a homeowner trying to order a replacement part or a technician performing routine maintenance, understanding and using the GC Number is indispensable. Next time you look at your boiler, take a moment to find and note down its GC Number – it could save you a lot of hassle in the future!
