Cornel 3-Column Textured Anthracite Products
Frequently Asked Questions
How does the 101mm depth of the Cornel 3 column radiator impact installation planning?
The Cornel 3 column radiator has a depth of 101mm which means when you add the standard wall brackets (approx 30-40mm) the total projection from the wall will be around 130-140mm so you must ensure this projection does not impede door openings or narrow walkways especially in hallways.
Why is the Textured Anthracite finish considered more practical than standard gloss finishes?
The Textured Anthracite finish has a matte slightly rough surface which is excellent at concealing minor scratches fingerprints and dust compared to high gloss finishes making it a low maintenance choice for high traffic family homes while offering a contemporary industrial aesthetic.
Does the 3 column configuration offer significantly more heat than the 2 column model?
Yes the 3 column design incorporates an additional vertical tube per section compared to the 2 column model which increases the surface area and consequently the heat output by approximately 30-40 percent for the same radiator width making it better suited for larger rooms.
Can I install the Cornel 3 column radiator on a plasterboard wall?
The 3 column Cornel is relatively heavy due to its steel content and water volume so while it can be installed on plasterboard walls you must ensure the brackets are screwed directly into the timber studs behind the plasterboard or use specialist heavy duty toggle fixings if stud alignment is not possible.
Are valves included with the radiator or do I need to purchase them separately?
Valves are not included with the Cornel 2 Column Textured Anthracite Radiator and must be purchased separately. This allows you to choose valves that match your specific pipework (Angled, Straight, or Corner) and design preference. For a cohesive look, it is recommended to pair the textured anthracite finish with matching Anthracite valves, or use Chrome or Brushed Nickel valves to create a stylish contrast that complements the industrial aesthetic of the column design.
What valve type do I need for the side connections on this radiator?
The Cornel 3 column radiator features side connections (1/2 inch BSP) so if your pipes come up from the floor you will need angled valves whereas if your pipes come out of the wall you will typically require corner or angled valves depending on the specific pipe orientation.
Is the mild steel material susceptible to rust in damp environments like bathrooms?
Mild steel can rust if exposed to constant moisture or if the paint finish is damaged so for bathrooms it is crucial to ensure good ventilation and to wipe down the radiator if it gets wet although the textured powder coating does provide a robust protective layer against humidity.
Why is a chemical inhibitor required for the Cornel 3 column radiator?
Mild steel radiators are prone to internal corrosion when in contact with oxygenated water so you must add a high quality chemical inhibitor to the central heating system upon installation to passivate the metal surface preventing the formation of black magnetite sludge and hydrogen gas.
Do I need to order wall stays for the taller vertical 3 column models?
For the taller vertical models (e.g. 1800mm high) it is highly recommended to use wall stays (top retaining brackets) to secure the top of the radiator to the wall preventing it from being pulled forward accidentally especially in households with children or pets.
Does the 10 year guarantee cover the radiator if I paint over the Textured Anthracite finish?
The 10 year guarantee covers manufacturing defects but painting over the original factory finish may void the warranty regarding the surface finish quality and could potentially hide leaks or other issues so it is generally advised against modifying the finish yourself.
Does the Textured Anthracite finish affect the heat output of the radiator?
Technically, different colours and finishes can have a marginal effect on the emissivity of a radiator, but for the Cornel Textured Anthracite range, this difference is negligible in a real world setting. The radiator is rated to perform at the specific BTU and Wattage outputs listed (e.g., 5500 BTUs for the 1800x611mm model) regardless of the finish. The steel construction is the primary driver of performance, ensuring you get the full rated heat output to keep your room warm and comfortable.
