If your Ideal boiler shows a Status C code and locks out, you’re likely wondering what this means and how to fix it. Here’s a straightforward guide to understanding and resolving Ideal boiler Status C issues, along with estimated costs.

What is Ideal Boiler Status C?

The Status C on your Ideal boiler indicates that the boiler is currently operating and burning fuel to heat water. This hot water circulates through your home’s radiators or is used for hot water taps. In simple terms, Status C means your heating system is active and working as expected.

Your Ideal boiler should display Status C as long as it’s heating water. Once the set temperature is reached, the boiler will stop, and the burner light, located next to the display screen, will flash. This is a normal part of its operation.

However, sometimes Status C may appear unexpectedly, signaling a problem. Let’s explore when that might happen.

When Does Boiler Status C Indicate a Problem?

Under normal circumstances, Status C is not a concern, as it merely shows that your boiler is running. However, if you notice the following, it could indicate an issue:

  • Boiler in Status C when not in use: If the boiler displays Status C even when it’s turned off, or you haven’t set the heating to be on, this could be a sign of a malfunction.
  • Flashing burner light and no heat: If the boiler stays in Status C, and the burner light flashes, but your home hasn’t reached the set temperature, your boiler may not be providing hot water as it should.

    • LPG/Oil Boilers: These work similarly to gas boilers but use liquid propane or oil. They are typically more expensive and less environmentally friendly.

    How to Identify Your Boiler Type

    Identifying your boiler type can be tricky, but with the right approach, you can determine what you have in place.

    Steps to Identifying Your Boiler:

    1. Check for External Components: Look for visible tanks, cylinders, and pipes connected to the boiler. The presence of a hot water cylinder typically means a system or regular boiler.
    2. Examine the Number of Pipes: A combi boiler will generally have five copper pipes, while a system boiler will have three, and a regular boiler will have two.
    3. Consider the Size of Your Home: Small homes often have combi boilers, while larger properties with multiple bathrooms will likely have system or regular boilers.
    4. Look for Manufacturer and Model Information: If you’re still unsure, check the model number on the boiler itself. Searching for the model online can give you specific details about the type.
