Air Trapped In Radiant Floor

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.

Air trapped in radiant floor.

Why the legalett radiant floor system works. But much of the sensible cooling will be done by the radiant floor. When water is heated in a hydronic heating system also known as a hot water heating system dissolved air is driven out. An air system can also be used to supply central air conditioning and air cleaning.

Air is the worst thing that can happen to any hydronic radiant heating system. Thus creating a vacuum this will suck air into the system. You will need one or two wall mounted fan coils in order to keep the humidity low enough so that no condensation occurs on the floor air dew point floor temp. 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.

Air trapped within a closed radiant system is the most common cause of inefficient system performance. In the summer it can also be used to cool the floor. Legalett air heated radiant floor heating systems are entirely embedded in concrete including the heater box. If pressure is dropping below the 15 psi it is an indication of air still trapped in your system.
