FAQ's
View AllDo 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.
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.
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.
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.
