Two designer radiators from the Aestus bathroom radiator collection complement one another very nicely, but if you can only pick one, which would it be? That’s why the main event today is… Aestus Sigma vs Aestug Fog!


Like always at DRS we make things easier for you, and this time we’ve put together a comparison of these two excellent bathroom  heaters to help you choose.



Both the Sigma and the Fog feature what we call ‘fingers’ which are used in different ways to create very unique shapes.



This radiator is a good one for the imagination, do you see a radiator? A moustache comb? Turn it one way and do you see a post-modern interpretation of moose antlers? Turn it the other way and are you now looking at icing dripping over the top of a cake?


Whatever it looks like, it’s both stylish and practical. It comes in three sizes; 1088mm tall, 1400mm and 1712mm, all at the same width of 600mm. Standard towel rails are at 500mm wide, but the extra width of the Sigma allows you to hang towels onto its fingers with the ample space you would expect. To give it the flexibility you would expect with a designer towel radiator, the Sigma is available in both Matt White and Matt Black to suit different themes.


The heat outputs produced are reasonable as well despite the flat shape, with the largest size producing 2668 BTUs. Not only is it an attractive radiator, it comes with a 15 year long guarantee, which for a steel radiator is absolutely phenomenal.



Contrasting to the long, open shape of the Sigma, the compact style of the Aestus Fog is a lovely distinction. The Fog’s appearance is an artistic interpretation of a pure white mist forming or fading in front of you – starkly the contrasting to the Sigma’s design.


The slightly oblong proportions of the Fog give it a satisfying overall appearance, with its two sizes coming in at 592mm high x 800mm wide and 790mm x 1100mm. It’s also available in both Matt White and Matt Black just like the Sigma, with the finish choice having a more dramatic effect due to the solid shape of the Fog.


Functionality was the main consideration for the final design of the Fog, and with 7 separate places to drape your towels to dry you have a large surface area where you can hang smaller towels, and even a large one completely unfolded if you felt so inclined!


While the heat output of the Aestus Fog is able to reach a higher total than the Sigma (2873 BTUs), the shape of the radiator might limit which bathrooms and where in each bathroom it can be placed. It requires a lot of space to install it, but if you do have that space it looks neat, warm and makes a wonderful design statement.



The dream choice between these two radiators would be to fit one into two separate bathrooms and have them quaintly match with one another. If your bathroom is very substantial then have them both within the same space, perhaps with the Sigma as the stand-alone towel radiator, and the Fog over a bath.


If you must choose between the two, then first you must consider whether you can actually fit one or the other in your home at a size big enough to give you the heat you need. If you could fit either of them, which will be more practical for the function you need.


They both look fantastic and have 15 year guarantees, as well as coming in the same black or white finish options, so the final deciding factor would be which one suits the space available for it the best without looking crammed in or lost.
