Air elimination in hydronic systems is an important requirement in terms of system efficiency and comfort. The presence of tiny air bubbles in system water causes noise and contributes to equipment degradation over time due to corrosion caused by bacteria growth. Purging the system repeatedly of un-wanted air requires many contractor call backs.
