FAQ's
View AllHow 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.
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.
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.
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.
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.
Are ethanol fireplace inserts difficult to install?
Unlike gas fireplaces or traditional wood burning fireplaces, our ethanol fireplace inserts require no venting, no gas line, no electricity - eliminating the need and cost of three sub contractors. They are simply mounted into the constructed main wall framework with the appropriate opening size for the fireplace insert selected. EcoSmart Fire’s ethanol fireplace inserts are extremely flexible and can be incorporated at any stage of your interior decorating, renovating or building works. For detailed specifications please contact us.
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.
