What is a column radiator?
In it’s simplest form, a column radiator is a well engineered, design classic, made to heat your home. This beautiful radiator design was created in the mid 60’s and is probably more popular now than ever before.
Columns - the term column refers to the vertical tubes that connect the top and bottom of each individual section of the radiator. The number of columns is what determines the depth of the radiator from the wall out into the room. Column radiators come in a variety of depths, the most popular being three, two and fours columns, in that order. Additionally, five and six column radiators are available where high heat output is required and space allows.
Sections - each section is joined together making the radiator grow in length. The minimum number of sections available is 3, which would only be approximately 160mm long. The largest number of sections we’ve joined to date is 50, which created a column radiator well over 2m in length. There are two methods of joining the sections, they are either welded together or joined using a nipple and gasket system. Both methods are well proven, popular and reliable.
The radiators are manufactured from mild steel. They are protected from corrosion externally by the powder coated paint finish or in the case of bare metal column radiators, a clear lacquer top coat is applied. Internally your radiators and central heating system is protected by inhibitors that are added to the system when it is filled initially and during regular maintenance. We have seen the introduction of a couple of aluminium column radiator designs in the past couple of years but as yet these are far too expensive and the style is not as appealing as the original tubular steel radiator design.
There are three main ways to mount your column radiator; wall mounted, support feet with top retaining stay or free standing fixed foot.
Wall Mounting - as standard we supply these radiators with wall mounting brackets. Most are European made, have a bracket that clamps onto the back tube, which then nests into the wall fixing. Chinese made radiators generally have a simple hook bracket that is not as well hidden or aesthetically pleasing. For clarity we aim to provide an image of wall mounting brackets for each radiator range on the page where you purchase that radiator.
Support Feet - the second most popular mounting method is to use a cast support foot. These are often used with particularly large or heavy radiators, or where installers are concerned about the strength and quality of the wall that the brackets are being attached to. The cast radiator foot is sometimes used to help create a more traditional style, as they were originally used on cast iron radiators.
Free Standing Feet - traditionally these were always welded to sections, but in the past five years most manufacturers have switched to slip-on feet. These are just as effective, as the feet can be secured directly to the floor with screws or bolts. However, if you require welded feet for additional strength and security, please call as we can supply these by special order.
Finish & Colour
Manufactured from steel tubing column radiators are generally finished with a powder coat paint treatment. Powder coating is a tough and durable surface finish that offers excellent heat resistance, corrosion resistance & high colour retention, giving you a long lasting, attractive smooth surface. Gloss white is the most popular finish, but with the growing popularity of anthracite, grey and black column radiators in gloss, satin and also lightly textured surfaces.
These can be viewed and touched in our Portsmouth showroom, along with a selection of colourful finishes, from subtle vintage greens to vibrant reds and blues. Ultimately, we can probably produce you a radiator in any colour you can think of. We even have bare metal column radiators available, that show off the detail of the manufacturing process. Bare or raw metal radiators are coated in a clear lacquer to protect them from corrosion, and they look amazing against brick walls and retro industrial style or in warehouse loft apartments.
