e-NRG bioethanol fires - The safer, eco-friendly fuel  

The e-NRG bioethanol fuel produces the best, most realisticbeautiful orange flames that are completely mesmerising. You and your guests will completely fall in love with the delicate flames that create a rhythmic flicker like a traditional campfire and can rise higher than any other competitor.  
The eco-friendly fuel is clean burning with no smoke, no soot and no ash. Bioethanol "bio fires" are a great alternative to gas fire for this reason. In comparison to other fuels on the market, the e-NRG bioethanol fuel not only produces the lowest odour but also has the longest burning time, putting your comfort first. This fuel has been tested on all EcoSmart Fire products, which is why we would recommend only the e-NRG brand.
