What are air vents and how do they work?
As solar heating systems heat the water, air can become trapped, reducing the systems’ efficiency and potentially causing damage to other components such as pumps or valves. This is where air vents come in – typically installed at the system's highest point, they allow trapped air to be released naturally while assisting in filling the system.
Most air vents utilise a valve or float that opens when air is present in the heating system, allowing trapped air to escape. For solar systems, automatic air vents, also known as auto air vents, are generally preferred due to their convenience and because they require less maintenance.
