Cornel 4-Column Radiators Products
Frequently Asked Questions
How does the 139mm depth of the Cornel 4 column radiator affect installation clearance?
The Cornel 4 column radiator has a substantial depth of 139mm which means when you add the standard wall brackets (approx 30-40mm) the total projection from the wall will be around 170-180mm so you must ensure this deep profile does not obstruct walkways or interfere with door swings before installation.
Why is the 4 column configuration the best choice for rooms with high heat loss?
The 4 column design incorporates four vertical tubes per section which significantly increases the surface area compared to 2 or 3 column models allowing it to generate a much higher BTU output per meter of wall space making it ideal for large high ceilinged rooms or areas with poor insulation.
Do I need to reinforce my wall to mount the Cornel 4 column radiator?
Yes, the 4 column Cornel is a heavy radiator due to the volume of steel and the water content (e.g. a 600x1194mm model weighs 40kg empty) so you must mount it on solid masonry walls or reinforce stud walls with timber noggins standard plasterboard fixings are likely to fail under the load.
Can I install the Cornel 4 column radiator using floor mounts instead of wall brackets?
Yes, for such a heavy radiator floor mounting is often the safer option especially on stud walls and you can purchase optional slip on or welded feet kits which transfer the weight directly to the floor structure rather than the wall.
How does the Delta T 50 rating apply to the high output of this radiator?
The high BTU outputs listed for the Cornel 4 column range are based on a Delta T 50 standard (75
Is the standard White RAL 9016 finish durable enough for a high traffic hallway?
Yes, the standard RAL 9016 finish is a high quality powder coating that is fused to the steel at high temperatures creating a hard wearing surface that is resistant to chips and scratches making it very suitable for busy areas like hallways where the deep radiator might be bumped.
What pipe centre allowance should I make for the valves on this 4 column radiator?
You generally need to add approximately 80-90mm to the total width of the radiator to accommodate the valves on either side so for a 1016mm wide model your pipe centres should be roughly 1100mm apart to ensure the valves fit comfortably without straining the connections.
Does the 10 year guarantee cover internal corrosion from system sludge?
The 10 year guarantee covers manufacturing defects but it does not cover damage caused by internal corrosion so it is critical that you flush the system and add a high quality chemical inhibitor upon installation to prevent magnetite sludge from building up in the bottom of the deep 4 column sections.
Why might I choose a lower 300mm height option in the 4 column range?
The 300mm high 4 column model is perfect for placing under low window sills or on dwarf walls in conservatories where vertical height is limited but you still need a massive heat output which the deep 4 column profile provides despite the short stature.
Are special heavy duty wall stays required for the 4 column models?
While the standard brackets are strong it is highly recommended to use wall stays (top retaining brackets) especially for the taller or wider 4 column models to prevent the radiator from being pulled away from the wall accidentally ensuring maximum safety.
