What is commonly the cause of an air-bound radiator?

• A. Defective air valve
• B. Blocked radiator fins
• C. Low water pressure
• D. Excessive heat generation

Answer: (A)

An air-bound radiator typically occurs when air gets trapped within the radiator system, which can prevent the efficient circulation of hot water or steam necessary for heating. The presence of a defective air valve is a common cause of this issue. The air valve, also known as an air vent or bleed valve, is designed to allow trapped air to escape. If this valve is malfunctioning, it may not open properly, leading to the accumulation of air in the radiator. When air is trapped, it can create an air pocket that inhibits water flow, leaving the radiator cold or unevenly heated. In contrast, while blocked radiator fins can impede heat transfer and affect the radiator's efficiency, they do not directly cause air to get trapped within the system. Low water pressure could potentially affect the ability of the system to pump water efficiently, but it is not a direct cause of air binding. Likewise, excessive heat generation may cause other issues, but typically it is not related to the air-binding phenomenon. Thus, identifying and resolving issues with the air valve is crucial in preventing and addressing air-bound radiators.
