2-Loop Radiant Heating Manifold with 24V Electric Thermal Actuators

2-Loop Radiant Heating Manifold with 24V Electric Thermal Actuators

This 2-loop radiant heating manifold is designed for hydronic radiant floor heating and other low-temperature hydronic heating applications using 1/2" PEX tubing. The manifold features 1" FPT supply and return connections, 1/2" PEX-compatible outlets, flowmeter valves, temperature gauges, automatic air vents, drain valves, and two 24V normally closed electric thermal actuators.

The pre-installed thermal actuators can be connected to compatible thermostats and zone controls to regulate individual heating loops. With two independently controlled loops, this manifold is suited for smaller radiant floor heating zones and other residential or light-duty hydronic heating applications.

Key Features
