Intergas Boiler Error & Fault Codes

Intergas Boiler guide by THS Plumbing & Heating Northampton

About Intergas boilers & why they're the best.

Intergas are well known for their ground-breaking and patented two-in-one heat exchanger ("So ground-breaking, Worcester Bosch group unsuccessfully tried to buy the patented") and has made it our first choice with many households throughout the Northampton and Wellingborough area.

Every Intergas boiler features their unique back-to-back, two-in-one heat exchanger. Separating the circuits for heating and hot water which also means there’s no need for a diverter valve which can fail in all other boilers. They also have the enviable reputation of NEVER HAVING A HEAT EXCHANGER FAILURE! Making Intergas our favorite boiler brand.

Most popular Intergas Boiler Faults.

While Intergas boilers are extremely reliable appliances as we have just explained, Intergas only have 2 common faults. #1, One being a common fault that every boiler has and that is a blocked condensate pipe. #2, Two is an error code 1 on the display which is very simple to fix and you shouldn't need one of our gas engineers.

The error code 1 fix
The reason why your intergas boiler is showing a error code 1 (Overheating) on the display is because of air in the system. Having air in the system can prevent water from circulating around the heating system. To remove this air, you need to bleed your radiators which you can do, and we will provide a step by step guide on how to do this very soon or you can either hire one of our heating engineers if your unable to do this yourself.

Intergas boiler warranty.

Depending on what boiler model you have, intergas boiler warranties are between 3 and 10 years. If your boiler was installed by one of our gas engineers we can extend the boiler warranty of up tp 12 years.
