FAQ's
View AllDo ethanol fireplaces smell?
All heating appliances have their own smell be it gas, wood or electric - ethanol fireplaces are no different. e-NRG ethanol fuel is made of fermented plants like sugarcane or corn and is essentially a liquid alcohol. To safely make “de-natured” and unfit for consumption, substances have been added. The burning of these substances may cause a slight smell upon initial lighting and when the flame is extinguished – similar to when you blow out a candle. e-NRG ethanol fuel is the only fuel recommended for your EcoSmart Fire ethanol fireplace. e-NRG ethanol fuel has the lowest odor and longest burn time on the market. The nice thing about using ethanol is that it’s not dry like gas or smokey like wood.
What are some key benefits – compared to other heating options?
When you choose ethanol as your fuel source over gas or wood, you are totally simplifying your installation requirements and costs. There's no flue or chimney required when burning ethanol, which means that you have the ultimate in design flexibility to achieve an open fire in so many more areas of your home - both indoors and out.
How does an ethanol fireplace work?
EcoSmart Fire’s ethanol fireplaces are self-contained, burning bioethanol fuel that is housed within the stainless steel container. A flame regulator controls and stabilizes the flame. With a designated filling area, and easy shut off mechanism, you can ignite the flame and turn it off in a matter of seconds. View this quick demonstration video to help illustrate the process.
Do bioethanol fireplaces produce heat?
Yes, although it does depend upon the size of the fireplace and also the size of the room itself. But a fire of an appropriate size can produce a good level of heat when considered properly in terms of its actual output and how it is positioned in the space. Bioethanol fires are a secondary source of heat that deliver a myriad of lifestyle benefits that can’t be achieved from primary heat sources such as radiators or reverse cycle air conditioning.
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.
Are ethanol fireplaces good for the environment?
EcoSmart Fire’s ethanol fireplace burners and fireplace inserts, when paired with our e-NRG bioethanol fuel are clean burning with the only byproduct being heat, steam and carbon dioxide (the same stuff we exhale). Unlike gas fireplace inserts and wood burning fireplace inserts, EcoSmart Fire’s ethanol fireplaces do not produce messy pollutants like soot, smoke, and ash.
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.
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
