The bypass valve is a complete unit (part of the boiler)connected to both the flow and return pipes below the boiler. Will be difficult to remove and not sure how to close it or remove as I expect the valve is within the fitting? Does anyone know if these are prone to fail

I have had numerous engineers out, many parts replaced, lots of money paid out and still it's not working correctly. (i'm in so deep now I need to get it sorted)
The heating side of the boiler fires up...
