Air vents in hydronic systems remove air accumulated in heating and cooling systems. This averts air staying in systems damages hydronic devices and improves system performance. Air vents prevent:
- corrosion due to the oxygen;
- pockets of air trapped in the heating emitters;
- cavitation in the circulation pumps;
- noise from air passing through the pipes.
