Argo Lo-Trim II Baseboard – 7 Ft. Hydronic Heating Assembly

The Argo Lo-Trim II Baseboard (Model 55LT27-7) is a 7-foot, fully assembled hydronic heating unit designed for residential hot water perimeter heating systems. This low-profile radiation element is engineered for quiet operation and uniform heat distribution, making it a reliable choice for both new construction and retrofit projects requiring 3/4" copper tube compatibility.

Product Overview

Constructed with a galvanized steel housing and aluminum finned copper tube, the Lo-Trim II series offers high thermal conductivity and corrosion resistance. Each unit includes a front cover, rear panel, support brackets, and a manually adjustable damper to regulate air flow and output. The slim design minimizes projection into occupied space while maintaining heat output performance across the length of the unit.

Core Features

• Material: Copper tube with mechanically bonded aluminum fins; housing is galvanized steel with a baked white enamel finish.
• Rated Output: Approximately 300 BTU/hr per linear foot at 180°F average water temperature under standard conditions.
• Overall Length: 84 inches (7 feet nominal)
• Connection Size: 3/4” CTS (copper tubing standard)
• Damper Included: Manually operated, factory-installed
• Cabinet Design: Low-profile layout for unobtrusive installation along interior wall perimeters

Installation Considerations

This baseboard assembly is suitable for wall-mount hydronic installations and is designed to support both series-loop and zone-valve configurations. For optimal performance and code compliance, installation should be performed by a qualified contractor. Secure mounting, loop sizing, and water temperature balancing are critical to achieving specified BTU output. Matching end caps, inside/outside corners, and splice plates are available for continuous runs or transitions.

Applications & Integration

• Use Case: Residential perimeter heating (baseboard hydronic systems)
• Compatibility: Designed for Argo Lo-Trim II systems; not to be mixed with other manufacturer elements
• Recommended Installations: Single-family homes, apartments, and multi-unit residential buildings
• Noise Management: Quiet operation due to secure cradle-mounted fin element and minimal expansion-induced chatter
