Its primary function is to act as a safety device. It monitors the appliance's temperature and automatically shuts it down if it exceeds a safe operational limit, preventing damage and potential hazards.
If your boiler repeatedly shuts down during operation, especially shortly after igniting, and a qualified engineer has ruled out other common issues like pump failure or blockages, the overheat thermostat may be faulty.
No, this is a safety-critical component within a gas appliance. Replacement must be carried out by a Gas Safe registered engineer to ensure correct installation and safety.
This thermostat (Part Number 801724) is compatible with Glow-worm models including 24CXI, 30CXI, 38CXI, 18SXI, 30SXI, 12HXI, 15HXI, 18HXI, 24HXI, 30HXI, and 38HXI.
Common causes include a faulty circulation pump that isn't moving water, blockages within the heating system or heat exchanger, or a malfunctioning thermostat itself.
Typically, overheat thermostats have a safety mechanism that requires the appliance to cool down to a safe temperature before it can be manually reset or allowed to operate again. Some may require a reset by a qualified engineer.
Warranty information typically varies by retailer. Please refer to the specific retailer's product listing for details on warranty coverage.
This could indicate the overheat thermostat is sensing a rapid temperature rise. Ensure the boiler's circulation pump is working correctly and there are no blockages in the system. If these are clear, the thermostat itself may be faulty and require replacement.
Check if the overheat thermostat has tripped. A faulty thermostat might fail to reset or signal correctly. A qualified engineer will need to diagnose if the thermostat is the cause or if another component is leading to an overheat condition.
This often points to an overheat condition. An engineer should check for potential causes like low system pressure, a malfunctioning pump, or a blocked heat exchanger, in addition to the thermostat's functionality.
Setup:
Installation of the Glow-worm Overheat Thermostat (801724) should only be performed by a qualified Gas Safe registered engineer. This is because it involves working on a gas appliance and electrical connections.
Compatibility:
This thermostat is specifically designed for and compatible with the following Glow-worm boiler models:
Always verify your boiler model number before purchasing.
Care:
As an internal component, the overheat thermostat requires no direct user cleaning or maintenance. Its function is internal. However, regular servicing of the boiler by a qualified engineer is crucial. This general maintenance helps ensure that other components are functioning correctly, reducing the likelihood of the overheat thermostat being triggered unnecessarily.
