What it is
The Sime 5188317 is a complete main heat exchanger for Sime gas boilers. The heat exchanger transfers heat from the combustion gases to the system water, forming the primary heat transfer component of the appliance. This part is supplied as a complete assembly rather than as individual sections.
Signs this part needs replacing
- Water leaking from the heat exchanger body or its joints
- Reduced heating output or poor system heat-up with no other obvious cause
- Overheating or repeated high-limit trips during normal operation
- Visible corrosion, scaling or soot build-up on the exchanger surfaces
- Combustion readings outside the manufacturer's specified range
Before you order
- Confirm the appliance model and serial number against the fit list above.
- Check the existing heat exchanger for the part number or identifying markings.
- Inspect associated seals, gaskets and connections for condition before fitting.
- Verify that the fault has been traced to the heat exchanger and not to another component.
