FAQ's
View AllHow long will my ethanol fireplace burn?
Burn times for our ethanol fireplaces vay based on flame size and fuel capacity of the burner. EcoSmart Fire’s ethanol fireplaces will burn between 8-13 hours when full.
What is the difference between gel and EcoSmart Fire’s ethanol fireplaces?
There are key differences between gel fireplaces and ethanol fireplaces in terms of operation and performance. Gel fireplaces are operated by inserting and lighting tin cans filled with gel. The cans act as the burner mechanism. Gel fireplaces do not produce a long coherent flame as known from ethanol fireplaces and can be difficult to extinguish. EcoSmart Fire’s ethanol fireplaces use a clean burning liquid fuel made with fermented plants. The fuel is housed in a ethanol burner that allows for safe and easy operation. Ethanol fireplaces produce a beautiful, vibrant dancing flame. Gel fuel should never be used within an ethanol fireplace.
How to install a TV or AV equipment above an ethanol fireplace?
This design can be achieved as long as the TV is protected. You have 3 possible solutions:
Solution 1: The TV needs a non-combustible mantel/ledge to act as a heat shield
Solution 2: The TV needs to be recessed in a niche
Solution 3: The TV needs to sit back off the level of the flame

How much does it cost to maintain an ethanol fireplace?
EcoSmart Fire’s ethanol fireplaces require little maintenance. It is important to keep the lid closed when not in use to keep debris out of the ethanol burner that can cause corrosion and damages. The 304 stainless steel tank is built to last a lifetime if proper cleaning procedures are done when needed.
How safe are bioethanol fireplaces?
EcoSmart Fire’s operating tools, procedures, and proprietary technologies were developed with safety as our top priority. Made from 304-grade stainless steel, EcoSmart Fire’s ethanol fireplace burners go through a deep-draw fabrication process that eliminates the potential for dangerous leaks. Additionally, our patented filling point is separated from the ignition zone and engineered so that the jerry can spout is fully supported prior to releasing the fuel supply. This eliminates the usual splash and spills that would otherwise occur when fuel is decanted into the burner while simultaneously reinforcing the maximum fill line within the burner. EcoSmart Fire’s ethanol fireplaces release heat, carbon dioxide (the same stuff we exhale) and steam. Allowing you to enjoy a clean-burning flame without the soot, smoke, ash or other harmful substances emitted by traditional wood burning fireplaces. When selecting an installation location for your ethanol fireplace it is important to consider the required minimum room sizes and clearances. Please reference our installation manual for more information.
What is a bioethanol fireplace?
A Bioethanol fireplace is an open fireplace that is fueled by bioethanol. A real flame is produced by the lighting of bioethanol, with a by-product being heat in the process. It is a fireplace that needs no flue for exhausting emissions, no utilities such as electricity or gas connection, and it uses a sustainable fuel source.
How long does it take to assemble?
There is virtually no assembly. Our Freestanding and Fireplace Grates ranges are designed to be placed into the desired location, secured into position, and operated immediately. Our Fireplace Inserts are designed to slot into place, secured and built around with your preferred finish – again a quick and easy installation – so your builder or interior designer will love you!
The longest part of the setup process is trying to figure out where you want to place it – be sure it complies with our clearance requirements particularly with regard to moving objects like curtains, tree branches and so forth.
Where do I buy ethanol fuel for my ethanol fireplace?
e-NRG is the only bioethanol fuel recommended for your ethanol fireplace. e-NRG has been produced for the lowest odor, most vibrant flame, and longest burn time on the market. e-NRG has undergone rigorous third party testing with all EcoSmart Fire ethanol fireplaces. Use of any other fuel may damage your unit and void your warranty. You can purchase e-NRG ethanol fuel at e-nrg.com for fast and free shipping.
