General info about bio ethanol fireplaces


 Understanding Bio Ethanol Fireplaces

All our fireplaces and burners are:

  • open for constant oxygen flow (without a glass front, or with open sides)
  • completely flueless
  • smoke-free
  • maintenance-free

They require:

  • no gas connection
  • no installation
  • no power supply


For those who have not heard much about the concept of Bio Ethanol Fireplaces, it may seem quite an unsual idea. However, for those who use them it is one of the most ingenious concepts, allowing everybody to have warming fireplace literally anywhere they wish.



Key Advantages of Bio Ethanol Fireplaces


Bio Ethanol Fuel


Bio ethanol fuel is a type of specially produced and denatured alcohol (toxicated so it becomes unsuitable for consumption), which is turned into a fuel for bio fireplaces. Our brand of Bio Ethanol Fuel - CRYSTAL - consists of 96.6% of clean ethanol, which has been derived from fermentation of certain crops and food waste. It is a completely renewable and green fuel.


Plants absorb Carbon Dioxide from the atmosphere. We use those plants as food and when processing food, there is food waste. With a little help of chemical enzymes, the biomass releases sugar and then natural microorganisms continue with the fermentation of the sugars, producing biofuel. Bio fuels have many uses in today's world, including fuel for bio cars or machines, within the cosmetic industry or eco-friendly home heating with bio ethanol fires.


The ethanol cycle looks like this:

Combustion of Bio Ethanol

As much as we would love to have a little bit more magic involved in our fuel production, it is in fact quite a straight forward, methodical and scientific process. Our Crystal Bio Ethanol Fuel has just above 96% ethanol content, it burns with a lovely large, orange flame, leaves no residue and releases virtually no odour. We say virtually - since our fireplaces burn with a REAL FLAME they cannot be completely odourless, but the very slight alcohol scent is barely smellable and 99.8% of customers are not bothered by it.

Combustion by-products (emissions) of ethanol burning are: minimal amounts of VAPOUR, CARBON DIOXIDE and HEAT. Emissions from burning ethanol are thus comparable to human breath emissions. As the alcohol fuel burns cleanly, there is effectively no need for extraction of toxins and having a flue or chimney. It is still a real flame, so always remember to employ common sense when installing or using a bio-ethanol-running fireplace.

This is what makes bio ethanol fires such a revolutionary product on today's market. As the way we heat our homes has changed in the last century, we don't rely on fireplaces to provide essential warmth anymore - we just want the focal point, the ambience, the cosiness of a real fire dancing in front of our eyes. Bio Fires can deliver that in nearly any average size or bigger room and it is, in fact, an instant solution.

Bio Fuel in Fireplaces

As we don't have supply of bio ethanol or any other alcohol on a tap (luckily...!), the fireplaces fuelled by this fuel need to be refilled regularly in order to get your flame. This solution has its pros and cons - the main benefit is that you tend to only buy what you need and you don't have to pay any fees or connection charges (like with gas) for something that you may only use occassionally. On the other hand, when you do intend to use your fireplace regularly you will need to go through the process of filling up and topping up your fuel level in the fireplace's burner pretty much every single time you use it, which can be a little fiddly. Still, most people are willing to put up with such a 'hassle' in return for having a beautiful warming flame in their homes without any costs and maintenance associated with real fires, chimney work or even gas fires and flue-lining.


There are many different models of fireplaces available on the market and some of them hold quite a lot of fuel. With most of our standard range aimed at residential homes, the actual fuelbox where the combustion happens has about 1-2 L capacity. The fuel therefore comes in handy 1 L bottles and is easy to store in a cupboard, basement, shed, etc.

How to operate a Bio Fireplace?

How does a bioethanol fireplace work


The principle of operating a Bio Ethanol fire is very simple:

  • Hang the fireplace on a suitable wall (it cannot be flammable and has to hold the weight of a fire) or position a freestanding unit in a desired place (not somewhere where it could be easily knocked over).
  • Just fill the fuel box with suitable bio alcohol to the level indicated in the instructions or on the container.
  • Use the funnel provided or possibly a measuring jug to pour the fuel, if necessary, use a torch.
  • Be very careful not to spill any fuel.
  • Then light the fireplace with a long lighter or a fireplace match.
  • For the first 5 to 10 minutes, the typical blue alcohol flame will appear which will gradually change into a beautiful yellow-red colour when the desired combustion temperature is reached.
  • The flame can be compared to a flame that comes from a wood fire.
  • You can extinguish the fireplace at any time by simply using our extinguishing tool (following instructions), cutting the oxygen supply and putting the flame out.


So, in simple words: our fireplaces burn eco-friendly Bio Ethanol Fuel, which is derived completely from plants, produces no more emissions than the human breath and gives you a naturally burning flame that looks like a gas fire.
Bio fires will take the edge out of a cold night without losing any emitted heat through a chimney. They are 100% heat efficient.


Safety First

It all sounds very simple and unproblematic, and it mostly is, when you use your bio ethanol fire as instructed and with common sense. However, you must never forget that you are dealing with a real flame, so you have to take all the safety measures into account.

Bio fires can be dangerous when:

  • you pour fuel into a burning fire
  • you spill your fuel and you ignite the fireplace without drying ALL the spillage
  • you place your fireplace in a hallway or in extreme draught area and have flammable objects nearby (i.e. curtains)
  • you hang or insert a fireplace into an unprotected wall or MDF structure


Whichever fireplace you have, you always need to take into consideration the size of your room and the size of the flame / heat emitted. Be prepared to open a window for 5 minutes after the fire has been on for an hour in case it gets too hot. People often refer to ethanol fireplaces as decorative (which they mainly are!), and they are surprised about the amount of heat produced. An average bio fire will produce approx. 3 kW of heat - an equivalent (or more) of an electric heater, and it will increase the temperature in your room (depending on the size of the room) on average by 2-3 degrees Celcius.
