RADIUS-DESIGN Combustion Chamber


  • Infinitely adjustable 5 mm strong flaps form stainless steel to regulate and erasure
  • The special ceramic provides even flames
  • Combustion chamber of stainless steel
  • Laser welded safety combustion chamber

Denatured ethanol largely burns to steam and carbon dioxide. The combustion chamber by RADIUS DESIGN means it is not necessary to use thickening agents as is necessary for gels and pastes. As such it allows clean residue-free burning.



Denatured Ethanol

The fires use Denatured Ethanol, which is sold in Australia and New Zealand under the trade name of Methylated Spirits.

Ethanol is an absolute alcohol, produced by the fermentation of renewable raw materials from agriculture and forestry products such as sugarcane, potatoes, bananas and more recently from wheat, barley and corn.

Ethanol produces de-nature ethanol with various substances for resale purposes and call it Denatured Ethanol.

For storage ethanol is classified as a Flammable Liquid Class 3, PGII. The user must familiarise themselves and comply with the storage and handlings regulations according to existing national regulations specific to this fuel.

Denatured Ethanol is classified as biodegradable.

When it burns the residual emission is largely carbon dioxide and water vapour.


Clean burning

The fuel can be purchased from any major chain stores or hardware stores.

The cost of 1 litre of Denatured Ethanol varies depending on the place of purchase. On average it costs approximately $3.50 per litre.

In general the 1.7 litre firebox of fuel on average will burn between 4 – 7 hours, depending on the opening width of the stainless steel covers.

You must only use Ethanol in the RADIUS DESIGN combustion chamber. It’s not necessary to use thickening agents like gels and pastes, as such it allows for clean residue-free burning.

There is no smoke when the Denatured Ethanol is burning. There is a slight smell when the fire is extinguished, similar to that when you blow out a candle; however it doesn’t last for very long.

“On behalf of all the residents of Sugarwood Grove Garden Villas, I am writing to thank you for providing the fire that contributed so much to the Christmassy ambience of our recent Christmas in July celebrations. It really set the scene as we entered the Community Centre and saw it glowing on the deck. Thank you from us all.”

Helen Ogle, Sugarwood Grove Garden Villas


“By far the best result of my dealings with Ambience Eco Fires has been the eco fire itself. German made, with absolute precision and beauty, it has established itself to be everything I had originally hoped for and “pictured”. Wanting the “portability” of a fire box, the “luxury & beauty” that can be afforded by a piece of art and seeking the acute ability to set a “mood” that only a dancing flame can procure, our “uni flame” eco fire has proved to be the perfect solution.
