3. Description
Generally, there is an exhaust valve/air vent valve installed on the brass manifold to discharge the air in the system, and solve the problem that the floor heating caused by the air block is not hot. The floor heating exhaust valve is divided into a manual exhaust valve and an automatic exhaust valve. The water usually dissolves in the air, and the solubility of the air decreases with the increase of the water temperature. When the water circulates in the floor heating system, the air gradually separates and climbs up the pipe, eventually gathering at the highest point of the system, so the exhaust valves are generally installed at the highest point of the system.
