Best Boiler Brands for Steam Systems
Nassau County's pre-war housing stock means steam radiators are everywhere. These brands excel at the thermal cycling that kills lesser boilers.

Why Coastal Homes Need Special Boilers
Long Island's barrier islands and south shore communities face constant salt air exposure that corrodes standard steel components within 5-7 years. These brands use 316L marine-grade stainless steel heat exchangers that resist salt corrosion for 15+ years. Our technicians have seen cast iron boilers fail prematurely in Long Beach and Island Park due to salt damage—don't make that mistake.
Best Boiler Brands for Older Homes
Nassau County's older housing stock — from 1920s colonials to 1960s split-levels — needs boilers that can handle radiators, steam systems, and decades-old piping. These brands specialize in exactly that.
The gold standard for cast-iron steam and hot water boilers. Weil-McLain's CGa and ECO series are specifically engineered for the thermal cycling demands of radiator systems found in Nassau County's 1940s–1960s housing stock.
Best for: Pre-war steam radiator homes
Burnham's Series 2 and IN series cast-iron boilers have been the go-to replacement for aging steam systems in Levittown, Hicksville, and East Meadow for decades. Local distributors stock parts extensively.
Best for: Post-war Cape Cods & ranches
Peerless boilers are built like tanks — their cast-iron sections are among the thickest in the industry. Ideal for homes with oversized radiators and single-pipe steam that punish lesser equipment.
Best for: Large colonial homes with radiators
For older homes converting from cast-iron to high-efficiency, Navien's NCB series combi boilers provide both heat and hot water in a wall-mounted unit — perfect when upgrading from baseboard to a modern hydronic system.
Best for: Homes upgrading from baseboard heat
Important Considerations for Older Homes
- Steam systems require boilers specifically rated for steam — not all brands offer them
- Older homes often have oversized radiators that need higher BTU output
- Cast-iron boilers handle thermal cycling better than steel in steam applications
- Single-pipe steam systems need boilers with generous water volume
- Local parts availability matters — choose brands stocked by F.W. Webb and Sid Harvey's
