Where must automatic air vents be located on a hot water heating system?

The lowest point in the system
Adjacent to the boiler
Located on the highest point in the system
Near the water pump

The correct answer is: Located on the highest point in the system

Automatic air vents must be located on the highest point in a hot water heating system in order to effectively remove any air bubbles or pockets that may become trapped. Option A, the lowest point in the system, would not effectively remove air as it would already naturally rise to the highest point. Option B, adjacent to the boiler, may not be the highest point in the system and may not be able to effectively remove air. Option D, near the water pump, may not be on the highest point and may not effectively remove air. Therefore, option C is the only correct answer as it ensures proper removal of air from the system.
