If you are looking for a cast iron wall radiator, note that the supplied cast iron options are freestanding rather than wall-mounted. Four Oswald Supply radiators are cast iron, steam-or-hot-water models in different lengths; the AB model is wall-mounted but made of aluminum. The table compares the choices by construction and stated dimensions so you can identify a replacement radiator or a wall-mounted alternative without confusing the two types.
| Product | Construction | Installation stated | Best suited for |
|---|---|---|---|
| Oswald Supply, 7-inch length | Cast iron, 4-tube | Freestanding | Compact replacement spaces |
| Oswald Supply, 10.5-inch length | Cast iron, 4-tube | Freestanding | Shorter radiator footprint |
| Oswald Supply, 14-inch length | Cast iron, 4-tube | Freestanding | Mid-size replacement option |
| Oswald Supply, 17.5-inch length | Cast iron, 4-tube | Freestanding | Buyers needing the longest listed cast iron model |
| AB 10-panel radiator | Aluminum | Wall-mounted | Buyers prioritizing wall installation |
Oswald Supply 7-Inch Cast Iron Radiator
This 4-tube Oswald Supply radiator is listed as 19 inches high, 4-7/16 inches deep, and 7 inches long. It is designed for steam or hot-water heating and is described as a freestanding radiator. The supplied features also note quiet operation and positioning as an efficient radiator replacement option.
Best for: A buyer replacing a short radiator or working with limited floor length who needs a cast iron unit. It is the shortest of the listed cast iron choices, making it the most compact option by stated length.
Limitation: It is not described as a wall-mounted radiator. Confirm that the existing heating system and connection arrangement suit the model before purchasing; the listing information provided does not specify connection details.
Oswald Supply 10.5-Inch Cast Iron Radiator
This model has a 19-inch height, a 4-7/16-inch depth, and a 10.5-inch length. It is a 4-tube cast iron radiator identified for steam or hot-water use. Oswald Supply describes it as freestanding, quiet in operation, and an efficient replacement option. The product information says multiple sizes are available, although buyers should check the selected listing for the exact size being ordered.
Best for: Homeowners looking for a compact cast iron replacement that is longer than the 7-inch model but shorter than the 14- and 17.5-inch models. Its stated length can help with preliminary space comparisons.
Limitation: The product is freestanding, not wall-mounted. The listed dimensions do not establish heating output, so do not assume that a particular length will heat a room adequately without checking system requirements.
Oswald Supply 14-Inch Cast Iron Radiator
This 4-tube model measures 19 inches high, 4-7/16 inches deep, and 14 inches long according to its product name. It is listed for either steam or hot-water heating. The stated features include freestanding installation, quiet operation from its cast iron construction, and use as a radiator replacement option.
Best for: Buyers who need a middle-size option among the supplied cast iron radiators. Its 14-inch length is longer than the 7- and 10.5-inch units but shorter than the 17.5-inch model, which makes it a useful size to compare when matching a replacement footprint.
Limitation: This is not a wall-mounted product. The listing does not provide a BTU rating or detailed system connection specifications in the supplied information, so verify those requirements separately.
Oswald Supply 17.5-Inch Cast Iron Radiator
The 17.5-inch Oswald Supply model is the longest of the supplied cast iron radiators. It is 19 inches high and 4-7/16 inches deep, with a 4-tube design intended for steam or hot-water systems. The listed features describe it as freestanding and quiet, and identify it as an efficient replacement option.
Best for: A buyer whose available floor space can accommodate the longest listed cast iron option and who wants to compare a larger footprint with shorter radiator choices. It provides a clear size step up from the 14-inch model.
Limitation: It is freestanding rather than wall-mounted. Its longer body may not fit a tight location, and the supplied specifications do not state heating capacity. Measure the installation area and confirm system suitability before choosing it.
AB Wall-Mounted 10-Panel Aluminum Radiator
This AB radiator is the only listed wall-mounted model, but it is aluminum rather than cast iron. Its stated dimensions are 28.54 by 3.66 by 22.36 inches, and the product information claims heat output of up to 5,768 BTUs. It has 10 panels, side air vents, a baked-paint finish, and plumbing-system operation. The listing describes quiet operation and provides recommended and maximum pressure figures.
Best for: Buyers who prioritize wall mounting over cast iron construction. It is the relevant alternative in this selection for a wall-mounted hot-water radiator, with the stated panel count and output available for comparison.
Limitation: It is not cast iron and is not listed as a steam radiator. The stated output and pressure information should be checked against the home’s plumbing system and room-heating needs before purchase.
Buying Guide: How to Choose a Cast Iron Radiator
Do you need wall-mounted or freestanding installation?
Start with installation style because it is the main difference in this product selection. The four Oswald Supply models are identified as freestanding cast iron radiators. The AB model is wall-mounted, but it uses aluminum. If both wall mounting and cast iron are essential, none of these supplied listings satisfies both requirements. Search for a product that explicitly confirms both features rather than inferring mounting style from the word “radiator.”
How should you compare radiator dimensions?
Measure the available installation area, including the height, depth, and length. The four cast iron options share a stated height of 19 inches and depth of 4-7/16 inches, while their lengths range from 7 to 17.5 inches. The AB wall model has different stated dimensions. Compare actual product measurements with the room and existing radiator location, and leave room for connections and access as required by the heating setup.
Does your system use steam or hot water?
The Oswald Supply models are described for both steam and hot-water use. The AB listing describes a plumbing-system hot-water radiator. That distinction matters: do not assume a hot-water model is suitable for a steam system, or the reverse. Check the product’s full specifications and consult a qualified heating professional when the system type or connection requirements are uncertain.
What does radiator length tell you about heating output?
Length helps compare physical size, but it does not establish how much heat a radiator will provide. The supplied Oswald product details do not state BTU output. The AB listing claims up to 5,768 BTUs, but that figure belongs to that particular aluminum model and should not be applied to the cast iron units. Match output to room requirements using verified product data and appropriate heating guidance.
When is cast iron a useful choice?
The listed cast iron models are described as quiet and intended as replacement options. Buyers comparing them can use their shared 4-tube design and stated dimensions as a starting point. However, the supplied information does not give weight, finish details, connection measurements, or output ratings. Confirm any specifications that affect installation, handling, or heating performance before ordering.
What should replacement buyers verify?
Record the existing radiator’s dimensions and identify its heating type before choosing a replacement. Confirm the new unit’s connection arrangement, required clearances, and heating capacity from the product listing or seller. A similar outer size alone does not guarantee that a radiator will connect to an existing system or provide the required heat. Professional installation guidance can help resolve system-specific questions.
