Why Automatic Air Venting Matters

Trapped air in hydronic systems is one of the leading causes of reduced heat transfer, noisy pipes, and circulator pump damage. The Watts HAV automatic air vent continuously purges air as it accumulates, keeping your system running quietly and at peak performance without the need for manual bleeding.
