The Easiest Way to Bring Your Old Fireplace Back to Life

Do you have an old fireplace and you don’t even remember the last time you used it because of all the mess involved? You are not alone.

These days more and more people are coming to a realization that traditional fireplaces are impractical and harmful to people’s health and our planet’s environment. If you are ready to start using your fireplace again in a mess-free, convenient, and responsible way, you can do that with the help of an ethanol insert.

Here is the easiest way to bring your old fireplace back to life:

Ethanol insert

Ethanol fuel, aka bio-ethanol, is used to fuel ethanol fireplaces. Bio-ethanol is a renewable energy source made from the fermentation of sugars or starches derived from recycled sugar beets, beetroot, and any sugar or starch that alcoholic beverages can be made from. 

Ethanol fuel is safe to use indoors and outdoors, as no harmful fumes are generated when burning – only small amounts of CO2 and Water Vapor… no soot, no smoke, no smell, and no residue. Since burning ethanol fuel doesn't produce any smoke or dangerous gasses, you can use your new upgraded fireplace with or without an operational chimney. As traditional wood burning fireplaces lose a lot of heat through the chimney, we recommend closing off the chimney to increase efficiency. You can do this by shutting the damper or blocking off the chimney with a metal plate.

Just like a traditional fireplace, ethanol fireplaces produce heat and are great for zone heating. Depending on the size of the burner, an ethanol fireplace can heat from 400 to over a 1000 sq.ft.

Operating an ethanol fireplace insert is easy:

1. Pour ethanol fuel in the burner through the funnel
2. Light up the fuel with a long lighter
3. Extinguish the flame by closing the damper
