The ARGO lt27-4 is a copper baseboard radiator measuring 4 feet in length, designed for hydronic heating systems in residential and light commercial applications. Copper fin-and-tube construction delivers efficient heat transfer from hot water circulating through the element, distributing warmth evenly along the baseboard. This type of radiator element is a standard component in forced hot water (hydronic) heating systems and is installed by licensed plumbers and hydronic heating contractors.
The lt27-4 is suited for use in rooms where zone heating is provided by a hydronic baseboard system. At 4 feet in length, it fits perimeter wall runs in smaller to mid-sized rooms. The copper element construction makes it compatible with standard hydronic distribution piping. Installation typically occurs as part of a new hydronic zone or as a direct replacement for a worn or damaged baseboard element of the same length.
Designed as an OEM-style replacement or new-install element for residential and light commercial hydronic baseboard heating systems accepting a standard 4-foot copper baseboard radiator element.
Installation is performed by a licensed plumber or hydronic heating technician. Shut down the boiler and allow the system to cool and depressurize before opening any connections. Follow local plumbing codes and manufacturer guidelines for fitting type and joint method when connecting to existing supply and return piping. Ensure the enclosure or cabinet is properly secured and that the element is level for correct convective airflow.
