Water heater return vents are ducts or openings designed to allow the circulation of air around a water heater, facilitating proper ventilation and preventing overheating. They help to expel exhaust gases safely, ensuring that combustion appliances operate efficiently and safely. Properly functioning return vents are essential for maintaining optimal performance and prolonging the life of the water heater. Without adequate ventilation, there can be a buildup of harmful gases, which poses safety risks.
