Frequently Asked Questions
What exactly is the Bare Metal Lacquer finish and how does it differ from a painted radiator?
The Bare Metal Lacquer finish is a transparent protective coating applied directly over the raw steel construction of the Cornel radiator. Unlike standard paint which covers the metal, this lacquer allows the natural weld lines, manufacturing marks, and unique discoloration of the steel to remain visible. This creates a distinct industrial or factory style aesthetic. Technically, the lacquer seals the steel to prevent oxidation and rust while preserving the authentic character of the raw metal.
How does the 4 column configuration impact the heat output and physical depth of the radiator?
The 4 column design features four rows of vertical tubes, maximizing the surface area for heat emission. This makes it the highest output model in the Cornel range per meter of length. For example, a 600mm x 1196mm model delivers an impressive 7008 BTUs. However, this performance comes with a significant product depth of 139mm. When planning installation, you must account for this depth plus the wall brackets, resulting in a total projection that often exceeds 160mm.
Is it safe to mount the Cornel 4 Column Bare Metal Lacquer Radiator on a stud partition wall?
Due to the dense 4 column steel construction and high water volume, these radiators are extremely heavy. A 600mm high x 1196mm wide model weighs approximately 40kg even before being filled with water. Installing this on a standard plasterboard wall with normal fixings is dangerous. You must use a specialized Stud Wall Bracket Kit or reinforce the wall structure with timber noggins to ensure the heavy duty brackets are anchored into solid wood capable of supporting the full operating weight.
Does the Bare Metal Lacquer finish require specific maintenance to prevent rust?
Yes, while the clear lacquer provides a robust seal, it requires careful maintenance to preserve its integrity. You should clean the radiator with a soft, dry cloth or a slightly damp cloth with mild soapy water. Crucially, you must avoid abrasive scourers or harsh chemical solvents, as these can strip the clear coat. If the lacquer is scratched deep enough to expose the raw steel, it can lead to rust spots, so careful handling during installation is essential.
What type of valves should I choose to complement the Bare Metal Lacquer finish?
To enhance the raw industrial aesthetic of the Bare Metal Lacquer, it is recommended to choose valves in a matching or complementary finish. Pewter, Black Nickel, or Unlacquered Brass valves work particularly well, adding to the vintage appeal. You will need to select Angled valves if your pipework comes from the floor, or Corner/Angled valves if your pipes emerge from the wall, connecting to the standard 1/2 inch BSP side inlets.
Are the Cornel 4 Column Bare Metal Lacquer radiators available for fast delivery?
Yes, unlike many bespoke coloured radiators which are painted to order and can take several weeks, the Cornel Bare Metal Lacquer range is typically held as a Stock item. This means they are often available for delivery within a shorter timeframe, such as 5 to 10 working days, allowing you to achieve a high end custom look without the extended lead times usually associated with special finishes.
How do I calculate the correct width for a 4 column radiator to heat my room?
The width of the Cornel radiator is modular, determined by the number of sections. Each section adds to the length and heat output. To size it correctly, first calculate your room's heat loss using a BTU calculator. Then, select a 4 column model that meets this requirement. This configuration is particularly useful for narrow wall spaces, as the 4 column depth allows you to generate high heat (e.g., 5000+ BTUs) from a relatively short radiator length.
Can I install this radiator on a low temperature heating system like a heat pump?
Yes, the Cornel 4 Column Radiator is technically well suited for modern low temperature systems such as heat pumps. Its massive surface area allows it to emit effective radiant heat even when the water temperature is lower (e.g., Delta T30) compared to traditional gas boilers. While you may need to size the radiator slightly larger than for a boiler system, the 4 column design ensures you get maximum output from the available wall space.
What is covered under the 10 Year Guarantee for the Bare Metal Lacquer finish?
The 10 Year Guarantee covers the structural integrity of the radiator, protecting against leaks and weld failures. Regarding the Bare Metal Lacquer finish, the warranty covers the adhesion and protective qualities of the clear coat. However, it is important to understand that the aesthetic variations, such as visible welds or darkening of the steel, are intentional features of the "raw" finish and are not considered manufacturing defects under the guarantee.
Why might I need Floor Mounts for the Cornel 4 Column Radiator?
Given the substantial weight of the 4 column models, Floor Mount Kits are a practical problem solving accessory if your walls are weak (e.g., lath and plaster) or if you wish to install the radiator in a conservatory with glass walls. These mounts bolt the radiator directly to the floor, taking the weight load off the wall entirely. They are available in a matching finish to ensure the industrial look is maintained from top to bottom.
