FAQ's
View AllCan 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.
Are EcoSmart Fires easy to install?
EcoSmart Fires are designed to be easily installed and operated. Without the need for a flue or pipe connection, EcoSmart Fires are extremely flexible and can be incorporated at any stage of your interior decorating, renovating or building works. For detailed specifications please contact your local distributor.
Why use an ethanol fireplace?
An ethanol fireplace is an eco-friendly and cost-effective alternative to gas fireplaces and wood burning fireplaces. Enjoy the warmth and aesthetic benefits of a traditional fireplace without the smoke, soot or ash in your home. Unlike gas fireplaces or traditional wood burning fireplaces, EcoSmart Fire’s ethanol fireplace inserts require no venting, no gas line, no electricity - eliminating the need and cost of three sub contractors.
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 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.
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.
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.
How do I fill my ethanol fireplace?
With EcoSmart Fire’s proprietary tools and procedures, filling your ethanol fireplace with e-NRG bioethanol fuel is fast and easy.
Step 1: Remove the bottle nozzle cap and carefully insert into the filling point
Step 2: Push and hold the green button. The nozzle will automatically stop filling once the reservoir is full.
Step 3: Replace the nozzle cap.
