FAQ's
View AllHow large of an area will my ethanol fireplace heat?
The heat output of our indoor and outdoor ethanol fireplaces vary based on the model selected. When used indoors, EcoSmart Fire’s ethanol fireplaces comfortably heat between 215 sq feet and 700 sq feet.
Is Bioethanol easily obtainable?
Yes, you can have fuel delivered to public and private premises in many countries.
Can EcoSmart Fires be installed everywhere?
Almost everywhere! EcoSmart Fires cannot be installed into small rooms that are less than our minimum room size which is burner specific. For all other installations, you must comply with our compulsory clearances and installation instructions. Approval from building authorities may be required prior to installation in your area. Please make sure you contact appropriate parties before installing your EcoSmart Fire.
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

Do EcoSmart Fire ethanol fireplaces give off any fumes or gases?
Bioethanol 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. Clean burning and eco-friendly, ethanol fuel releases heat, carbon dioxide (the same stuff we exhale) and steam.
What is bioethanol fuel?
Bioethanol (also known as methylated spirits or simply ethanol) is a form of renewable energy. It’s a clear, colourless liquid that’s commonly made from fermenting the sugar and starch components of plant by-products like sugarcane and grain crops.
What are the benefits of a zero clearance ethanol fireplace insert?
EcoSmart Fire’s Flex Fireplace Series has the necessary clearances to combustible frame components already built-in meaning they can be framed with wood studs. This gives you the freedom to install your ethanol fireplace insert in small and unique spaces. When selecting a location for the fireplace it is important to consider the required minimum room sizes and clearances. Please reference our Flex Series installation manual.
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.
