FAQ's
View AllDo 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 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

Can I install a Fireplace Insert into my existing fireplace?
EcoSmart’s Fireplace Inserts are mostly used for new construction when an entirely new fireplace is desired for a given space. They are not designed for the conversion or remodelling of an existing masonry or gas fireplace but could be used if dimensions align. To convert an existing fireplace we recommend using our Fireplace Grates or Ethanol Burners as noted above. Ensure that the flue has been closed off and the relevant suppliers have officially detached all connections to utilities.
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.
How 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.
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.
You can view a step-by-step filling video.
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 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.
