domestic cast iron boilers is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
Technical advantages Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
Internal inspections of cast-iron boilers can prove to be difficult or almost impossible. Threaded plugs on the cast iron boiler could be removed, but the inspector will see very little past the immediate vicinity of the opening on many cast iron boiler designs.
Domestic hot water coil optional; Robust cast-iron heat exchanger; Installer-friendly features; More Btu's per section than ordinary boilers; Metal push nipple to connect individual sections; 25 Year Limited Lifetime Warranty; Tankless Heater Features; Can accommodates a larger coil to maximize output; Cover plate is visible for easy inspection
When you purchase a residential boiler, water heater or radiator from U.S. Boiler Company, you know you're getting the best in comfort, durability and safety. Three of our current models meet the Energy Star efficiency standards.
System 2000 by Energy Kinetics was not only the first steel boiler to successfully compete with cast iron boilers, but it was the first one to surpass cast iron in its energy efficiency, saving consumers money. Plus, its specially formulated steel is uniformly thicker than the 5/32” thickness now found in many cast iron boilers.
Cast iron boilers are a popular choice for both hot water and steam heating applications. We carry a wide selection of cast iron boilers from the top brands, so you can be sure to find one for your needs.

Burnham ES2™ and Burnham Series 3™ – The unmatched performance of the ES2™ cast iron gas-fired water boiler is the optimal replacement boilers for homes with existing chimneys. They are available for natural or LP gas and can be equipped with optional energy saving packages to reduce fuel consumption by up to ...
The material the boiler is made of matters much less than the design of said boiler. My most efficient, highest quality boiler, the Vitola, is made primarily of steel. But I have seen many landfill boilers that were made of steel. All sectional boilers are made of cast iron and have varying designs. They range from great to landfill, also.
Determining actual system efficiency for cast iron boilers Why I started this investigation Cast iron boilers have proven to be extremely reliable, being very simple in design and using standardised parts. They have been the workhorse for central heating since the early days of gas, oil or coal central heating.
