Hi RobĀ 

The image above is a simplified model whilst I get to grips with the setup. In reality the water will be pumped around the coil in a closed loop. I have read I can update the boundry conditions at each iteration to ensure the water is recirculated at the same temprature rather than say 600k at outlet and 300k at inlet.

Thank you I have tried using share topology but belive importing the assembly from cad has created some issues with sliding interfaces and non existant surfaces.
