With 82% AFUE efficiency, you can expect to save approximately $34 annually compared to an 80% efficient boiler. Key features like Heavy-gauge cast iron sections and Natural draft venting make it a compelling choice. It's particularly well-suited for pre-war steam radiator homes in garden city, hempstead, and freeport.

Pre-war steam radiator homes in Garden City, Hempstead, and Freeport

Expert Review: Weil-McLain EG-45

The Weil-McLain EG-45 is the gold standard for residential steam boilers on Long Island. In pre-war homes from Freeport to Garden City, the EG series has been keeping steam radiators warm for generations. When your 1920s steam boiler finally dies, the EG-45 is almost certainly what should replace it.

Why Steam Specialists Choose the EG Series

The EG-45 features heavy-gauge cast iron sections specifically designed for the thermal stress of steam operation. Steam boilers cycle on and off repeatedly throughout heating season, expanding and contracting with each cycle. Lesser cast iron cracks under this stress—the EG handles it for decades.

Best Applications for Nassau County Steam Systems

The EG-45 fits homes with 4-6 steam radiators—typical of Levittown and Massapequa 3-bedroom homes. Larger pre-war homes in Hempstead, Freeport, and Rockville Centre may require the EG-55 or EG-65 with additional sections. We size steam boilers based on the connected radiation (EDR), not square footage.

Lifetime Warranty

The EG series carries Weil-McLain's lifetime limited warranty on the cast iron heat exchanger when installed by a licensed contractor. This warranty has actual value: cast iron steam boilers truly can last 40+ years. We service EG boilers installed in the 1980s still running strong.

Steam System Expertise Required

Steam boiler installation requires specialized knowledge. Proper piping, near-boiler piping, and Hartford Loop connections are critical for safety and efficiency. The EG-45 price includes professional installation by our steam-certified technicians who understand the nuances of these systems.
