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.
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.
What maintenance is required for ethanol fireplaces?
Clean your EcoSmart Fire unit after you have used 50 liters [13.20 Gal.] of fuel or as soon as you notice black deposits on or near the burner of the ethanol fireplace. Black marks can be removed from the stone, solid surfaces or stainless steel with a mild abrasive washing product such as JIF or similar. It is recommended to test a small area first to ensure the cleaning product chosen is appropriate and will not mark or damage the surface. Burners can be washed as required in hot soapy water (even in your dishwasher) from time to time and the internal mechanics won’t deteriorate like some other brands as all internal parts are stainless steel.
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.
How much does it cost to maintain an ethanol fireplace?
EcoSmart Fire’s ethanol fireplaces require little maintenance. It is important to keep the lid closed when not in use to keep debris out of the ethanol burner that can cause corrosion and damages. The 304 stainless steel tank is built to last a lifetime if proper cleaning procedures are done when needed.
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.
Why use bioethanol?
Bioethanol, a renewable energy, is the cleanest and most efficient fuel on the market, which means there are no emissions and no soot or ash to clean up.
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.
