Air Trapped In Radiant Floor

When water is heated in a hydronic heating system also known as a hot water heating system dissolved air is driven out.

Air trapped in radiant floor.

Why the legalett radiant floor system works. Thus creating a vacuum this will suck air into the system. Legalett air heated radiant floor heating systems are entirely embedded in concrete including the heater box. It is a closed loop system where air is moved through either 2 or 4 inch pvc tubes which are non corrosive so that no dust from the air in the home is introduced into the system.

Central heating systems use either a furnace with hot air ducts or a boiler with hot water hydronic pipes and radiators including radiant under floor heat. Air is the worst thing that can happen to any hydronic radiant heating system. Air trapped within a closed radiant system is the most common cause of inefficient system performance. Fortunately it s an easy problem to solve and won t become an issue at all if care is taken during the initial filling process.

Eventually this air can become trapped in the hot water lines. In the summer it can also be used to cool the floor. If pressure is dropping below the 15 psi it is an indication of air still trapped in your system. An air system can also be used to supply central air conditioning and air cleaning.
