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.
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.
Do ethanol fireplaces give off heat?
EcoSmart Fire’s indoor ethanol fireplaces are ventless, meaning all the heat stays in the room rather than escaping up a flue or chimney like it would with a traditional wood burning fireplace. Increased heat retention also means increased fuel efficiency. EcoSmart Fire’s collection of ethanol fireplaces offer a heat output ranging from 5,000 BTU - 20,000 BTU’s.
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.
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.
Do 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.
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

Where is the best place to install an ethanol fireplace?
Our ethanol fireplaces can be installed virtually anywhere - in walls, cabinets, high rise buildings, commercial / residential / hospitality spaces, indoors and outdoors. Because EcoSmart Fire’s ethanol fireplaces are ventless, they require no gas line, no electricity, and no chimney for a hassle free and cost effective installation. Our ethanol fireplaces have been designed and tested with safety as our top priority. We have outlined requirements for each ethanol burner, ethanol fireplace insert, and ethanol freestanding fireplace in our collection. These guidelines include minimum room size requirements and clearance recommendations for flammable materials and movable objects. Please refer to our manual for more information.
