4-Loop Hydronic Heating Manifold with 24V Electric Thermal Actuators

The WiseWater 4-loop hydronic heating manifold is a complete manifold assembly for radiant floor heating and other hydronic heating systems. It includes four 24V normally closed electric thermal actuators, 1/2" PEX adapters, flowmeters, temperature gauges, an automatic air vent, and drain components. The manifold features 1" FPT supply and return connections and four individual 1/2" heating loop outlets. Each loop includes a flowmeter for monitoring and adjusting flow, while the electric thermal actuator can be connected to a compatible thermostat or zone control system for individual circuit control. Key Features 4-loop hydronic heating manifold 1" FPT supply and return connections 1/2" PEX adapters included 4 × 24V, 2-wire normally closed electric thermal actuators Listed flow: up to 1.4 GPM Flowmeters for individual loop flow monitoring and adjustment Dual-scale temperature gauges for supply and return temperature monitoring Automatic air vent and drain components with outlet caps Stainless steel manifold construction 24V Electric Thermal Actuators Each heating loop is equipped with a 24V, 2-wire, normally closed (NC) electric thermal actuator. When connected to a compatible thermostat or zone-control system, the actuators can control the opening and closing of the individual heating circuits. Thermostat and zone-control equipment are not included. Flow & Temperature Monitoring Each loop includes a flowmeter/valve assembly for visual flow monitoring and adjustment. Dual-scale temperature gauges provide a convenient way to monitor supply and return temperatures at the manifold. Air Vent & Drain The integrated automatic air vent helps remove accumulated air from the manifold. The drain components can be used for system filling, draining, and routine servicing.
