Cornel 2-Column Radiators Products
Frequently Asked Questions
How does the 65mm depth of the 2 column Cornel radiator compare to standard panel radiators?
The 2 column Cornel has a depth of just 65mm which is comparable to a standard Type 11 single panel radiator making it an excellent space saving option for narrow hallways or behind doors where you want the aesthetic of a classic column radiator without the bulk of deeper 3 or 4 column models
What is the correct method for calculating the total wall projection for this specific 2 column model?
To determine the total projection you must add the radiator depth of 65mm to the wall bracket distance which is typically around 30mm to 40mm resulting in a finished projection of approximately 95mm to 105mm from the wall surface which is significantly slimmer than the 3 column version
Can the Cornel 2 column horizontal radiator be floor mounted instead of wall mounted?
Yes while supplied with wall brackets as standard you can purchase optional slip on or welded feet kits to floor mount the radiator which is particularly useful if your walls are constructed from stud work or plasterboard and cannot support the weight of the steel radiator
How does the heat output of the 2 column design compare to the 3 column version of the same size?
The 2 column design has fewer tubes and therefore less surface area than the 3 column equivalent so for the same height and width the 2 column model will output approximately 30 to 40 percent less heat meaning you may need a wider radiator to achieve the same BTU output
Is the Cornel 2 column range suitable for low temperature heating systems like heat pumps?
Yes the Cornel 2 column range is compatible with heat pumps but due to its lower surface area compared to deeper models you will need to size the radiator significantly larger using a lower Delta T correction factor to ensure it provides adequate warmth at lower water flow temperatures
Why is the RAL 9016 Traffic White finish the standard for this range?
RAL 9016 is a bright clean white that reflects light well and blends seamlessly with modern architectural trims and PVC window frames avoiding the yellow creamy undertone found in older RAL 9010 finishes which ensures a crisp contemporary look
What are the specific valve requirements for this horizontal column radiator?
The Cornel 2 column horizontal radiator has side connections standard 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 pipe orientation
Does the 10 year guarantee cover the radiator if installed in a high humidity bathroom?
The standard 10 year guarantee covers manufacturing defects but mild steel radiators can rust in high humidity environments if the paint surface is scratched or compromised so for bathrooms it is crucial to ensure the room is well ventilated and the radiator surface is kept dry to maintain the warranty validity
How do I bleed the Cornel 2 column radiator to ensure even heating?
You should turn off the heating system to stop the pump then use a radiator key to open the bleed vent located at the top side of the radiator until water trickles out which releases trapped air pockets that cause cold spots at the top of the columns
Is a chemical inhibitor necessary for this mild steel radiator?
Absolutely mild steel is prone to internal corrosion when in contact with water and oxygen so you must add a high quality chemical inhibitor to the central heating system during installation to passivate the metal preventing the build up of magnetite sludge and hydrogen gas which protects the radiator lifespan
