What is the angle of goose neck in boiler?

The angle of a goose neck in a boiler typically refers to the bend in the piping that connects the boiler to the chimney or flue. This bend is usually designed at an angle of around 45 degrees to facilitate effective gas flow and minimize pressure loss. The precise angle can vary based on the specific design and requirements of the boiler system. Proper installation is essential to ensure efficient operation and prevent issues like backpressure or condensed moisture buildup.
