What it is
The Alpha 1.023716 is an 18mm diameter pipe that connects the heat exchanger to the flow outlet on Alpha CD12S and CD20S LPG boilers. It carries heated water from the heat exchanger into the boiler's flow circuit. This is the pipe only.
Signs this part needs replacing
- Water leaking from the pipe or its connections
- Visible corrosion or rust on the pipe surface
- Scale or debris build-up restricting flow through the pipe
- Reduced hot water performance or overheating linked to poor circulation
- Unusual noise from the heat exchanger area during operation
Before you order
- Confirm your boiler model and GC number against the fitment list
- Check that part number 1.023716 matches the pipe currently fitted or the manufacturer's parts list
- Verify the pipe diameter and connection points before fitting
