The Gledhill Gulfstream A-Class boiler introduced an innovative design by combining a thermal store with a gas-fired boiler, all within a single unit. While they perform efficiently when operational, the design implementation faced shortcomings, leading to frequent and costly breakdowns. Eventually, Gledhill ceased production of Gulfstreams and withdrew technical support for the gas components, leaving owners without adequate assistance.



Owners often encounter a frustrating pattern of multiple, unrelated breakdowns shortly after each repair, causing frustration for both users and repair technicians. As a result, few Gulfstream A-Class boilers remain in operation today, with many disappointed owners having replaced them long ago.
If you encounter issues with your Gulfstream A-Class boiler, here are some troubleshooting steps to consider before calling for assistance:

  1. No Heating or Hot Water:

    • Check for any red lights on the front panel and press the reset buttons, including the hidden button beneath the black cap.
    • Verify the settings using the user controls and consider using emergency backup heating options if necessary.
  2. Cold Radiators:

    • Ensure the timer is set to ON and override it if needed.
    • Check the room thermostat and adjust it accordingly.
  3. No Hot Water:

    • Unfortunately, there are limited user checks for this issue, so calling an engineer may be necessary. In the meantime, utilize emergency hot water backup controls if available.
  4. Gas Supply:

    • Confirm that the gas supply is turned ON, as it may sometimes be overlooked or depleted unexpectedly.

By following these steps, you may be able to identify and resolve minor issues with your Gulfstream A-Class boiler without the need for professional assistance. However, for more complex problems or persistent faults, contacting a qualified engineer is recommended.

    By addressing these potential faults systematically, technicians can effectively troubleshoot the Gledhill Gulfstream A-Class system, ensuring optimal performance and customer satisfaction.
