What is an ethanol fireplace insert?

EcoSmart Fire’s fireplace inserts are ready to install heating appliances that include single or multiple ethanol burners within a designed zero-clearance enclosure. Choose from over 219 single sided, double sided, bay, peninsula, island, and bench fireplace styles at multiple lengths. 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. Simply secure the ethanol fireplace insert in the framework, finish the surround, and it’s ready for use. EcoSmart Fire’s ethanol fireplace inserts can be installed virtually anywhere - in walls, cabinets, small spaces, high rise buildings, commercial spaces, indoors and outdoors.

Can I extinguish my ethanol fireplace before the fuel has burnt?

Yes, you can turn your EcoSmart Fire ethanol burner off at any given time, even if there is ethanol still left in the burner. It is recommended however, that you leave it to burn until it completely runs out. The shut off mechanism is there for security and safety for those times when you need to leave the house, as it is not safe to leave a fire unattended. You need to wait until your appliance cools to room temperature (60 minutes) before re-igniting, this is because hot vapours are a hazard and may cause a strong, initial ignition if the ethanol has not cooled long enough. This is also to ensure that the flame has been totally extinguished and that the appliance is safe to refuel if the amount of fuel in the burner at that time is insufficient for your next ignition / use.

Is their heat output similar to a gas heater?

Burning bioethanol is similar to gas, but the room doesn't dry out like it does with gas - a more gentle, softer heat is created. Heat-wise, it depends on the models being compared. Some of our bioethanol burners output 15,000 BTU and can heat up to 60sqm of living space. Bioethanol is not, however, on an adjustable thermostat. Some may be turned up and down, but you can't control the room temperature in the same way as you do with gas on mains

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.

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.

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.

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 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.
