4' Cast Iron Hydronic Baseboard, Snug, Complete

Weil-McLain Snug Cast Iron Baseboard – 4 Ft. Section for Hydronic Heating

The Weil-McLain 190100012 Snug Cast Iron Baseboard is a 4-foot hydronic heating section designed for use in gravity-fed and low-pressure hot water systems. Its cast iron construction offers high thermal mass, providing both radiant and convective heat transfer for stable and efficient room temperature control. This unit is suitable for perimeter installation beneath windows or along exterior walls, where cold air infiltration requires offsetting heat output.

Product Construction

• Length: 48 inches (4 feet nominal)
• Material: Cast iron – sectional design
• Finish: Factory-primed, suitable for field painting
• Working Pressure: Rated up to 50 psi
• Mounting Type: Floor-mounted; intended for wall-adjacent placement using cast iron supports (not included)

Key Functional Features

• Radiant/Convective Output: Combined radiant surface area and natural convection allow for uniform heat delivery across the zone.
• Thermal Retention: Cast iron body retains heat after circulation stops, helping reduce system cycling and temperature swings.
• Downdraft Mitigation: Designed for use along exterior walls to counteract cold air infiltration and window-related thermal losses.
• System Compatibility: Suitable for integration with gravity, series-loop, or zone-valved systems using appropriately sized connections.
• Field Configurability: May be joined to additional baseboard sections or fitted with corners and extensions from the Snug series for continuous runs.

Installation Considerations

This product is intended for use by licensed plumbing or HVAC contractors. Installation requires precise alignment, stable floor mounting, and system pressure testing. When used in retrofits or expansions, verify compatibility with system head loss and boiler capacity. Proper wall clearance, leveling, and connection to supply/return piping are essential to ensure full output and code compliance.

Applications

• Residential perimeter hydronic heating
• Gravity-fed or pumped low-pressure hot water systems
• Retrofits of historic or cast-iron panel heating systems
• Zone-based systems in rooms with moderate-to-high heat loss
