When we buy a new vacuum cleaner, a new TV, stereo, games console and so on, we’re always conscious of the guarantee given with it (or at least you get pestered to buy the super annoying “3 years of cover for only £120 per year!”). Any way you slice it, guarantees are important to know about.


It’s only natural to want a little reassurance when making an investment of both your money and your valuable time into something, and down the line could need replacing as well should something go wrong. The guarantee means that your designer radiators are covered in the event of a leak, or if they don’t perform as well expected due to a manufacturing fault.


There’s nothing more reassuring that should anything be amiss with your designer radiators, you will receive a free of charge replacement model. What your radiator is made of will likely play a big part in your guarantee’s length, so read on to find out more.



Steel designer radiators are the standard for the designer radiator industry. They are easy to work with, and relatively cost effective to manufacture. Most painted radiators as well as chrome model are made from steel, and the industry standard for them is a guarantee of 5 years.


Be wary of unscrupulous retailers who are offering 10 years (or sometimes even more!) on steel designer radiators, the manufacturer won’t exist in a few years’ time, never mind 10 or 20 years. The absolute highest quality radiator producers throughout the world (Bisque, Eskimo, Zehnder, Arbonia, MHS etc), will only provide a 5 year guarantee on their good quality steel with carefully manufactured designs.



Similar to steel, aluminium is a great material for designer radiators to be made from, as it’s lightweight and convects thermal energy very efficiently. The most common warranty for aluminium products is 5 years, but it isn’t too uncommon to see 10 years being offered by the likes of Aeon, a luxury, high-end of the range brand.

Radiators like our own DRS Brescia are perfect examples of the efficiency of aluminium. Using only 1/10th of its design to hold water means that it is tremendously efficient, and looks simple but sleek at the same time.



The cream of the crop for radiator quality and guarantee length is stainless steel. By making an alloy of both steel and chrome, we create an opulent looking metal which in the right hands can be worked into amazing shapes, and will last for decades.


Stainless Steel is where the biggest swings in warranties come about. Most manufacturers offer 20-25 years for their stainless steel beauties (Aeon and Reina for example), but some brands like SBH offer exceptionally sturdy, full life-time guarantee on their designer radiators.



It may seem odd because of how susceptible iron is to deterioration, but our cast iron designer radiators from the amazing specialist Paladin are so carefully protected, sealed and finished that they can confidently offer a full 10 year guarantee on their products.

If you are something of a traditionalist, beautiful cast iron models like the Neo Georgian are perfect for your tastes, but works quite rebelliously in the contemporary home as well.



While sometimes it’s easy to sit back and relax once you have made your purchase, safe in knowing that your guarantee protects you, there is a degree of responsibility on your end to reasonably look after your heating system and your radiators.


The simplest one, and one which you should probably be doing already, is having your heating system serviced and cleansed with a corrosion inhibitor once per year. Chemical cleansing means that the water has been neutralised, and will gently pass through your system, greatly prolonging the lifespan of your designer radiators.


With the proper care, even steel designer radiators can last upwards of 20 years, so make your purchases wisely and you’ll only need to replace them once they’ve gone out of style, not when they’ve gone south.
