Modern 2-Pipe Steam Systems
Our 2-pipe steam alternum readiators are designed for efficient, reliable heating in residential and commercial buildings. Built from high-performance aluminum, these modern radiators provide faster heat response, lighter weight, and a cleaner profile than traditional cast iron radiators—making them ideal for both replacements and new installations.
Engineered specifically for 2-pipe steam systems, these radiators are not compatible with 1-pipe steam systems, ensuring proper steam flow, consistent heat output, and long-term system performance.
System Compatibility: Designed exclusively for 2-pipe steam systems. Not compatible with 1-pipe steam systems.
Radiator Type: Modern aluminum steam radiator offering fast, even heat distribution with a slim, space-saving profile.
Construction: Manufactured in Italy using high-quality, fully recyclable aluminum for durability, efficiency, and long service life.
Performance: Delivers high heat output with quicker warm-up times compared to traditional cast iron radiators.
Pressure Rating: Pressure tested up to 232 PSI (16 bar) for dependable residential and commercial operation.
Corrosion Protection: Internally treated with an anti-corrosion coating to protect the radiator and heating system.
Installation: Includes wall-mount brackets and mounting hardware. Professional installation by a licensed plumber or HVAC contractor is recommended.
Valves: Radiator valves are sold separately to allow proper matching to your system layout.
Finish: Durable white powder-coat finish designed to complement modern and transitional interiors.
Applications: Ideal for homes and buildings with existing 2-pipe steam systems, completing renovations or looking for cast iron radiator replacements.
Warranty: Backed by a 2-year manufacturer warranty.
Shipping: Ships free from Modern Warmth’s U.S. warehouse.
