A Zone by Actuator Hydronic Radiant System is a type of radiant heating system that uses thermal or motorized actuators to control the flow of heated water through individual loops in a manifold. This system is commonly used in radiant floor heating, providing precise and efficient control of heating in different zones.
How It Works:
-
Heat Source: A boiler or water heater generates hot water.
-
Circulation Pump: A primary pump circulates hot water through a main manifold.
-
Manifold with Actuators: Each zone or loop is connected to the manifold, and each connection is equipped with an actuator. Actuators are devices that open or close the flow of water to specific loops.
-
Thermostat Control: Each zone has its own thermostat. When heat is needed, the thermostat sends a signal to the actuator, causing it to open. Hot water then flows through the specific loop to heat the zone.
-
Heat Distribution: The heated water circulates through PEX or similar tubing installed in floors, walls, or ceilings, providing gentle and consistent radiant heat.
-
Closing the Loop: Once the desired temperature is reached, the actuator closes the valve, stopping the flow of hot water to that zone.
