1. What are the running costs?

Usually about £1/h, depending on the size of the flames and the amount of fuel purchased (the more stock you buy the cheaper it gets). A full fireplace container will burn for about 3 to 4 hours (depending on the model). If you buy small amounts of fuel, your cost price will increase signifinatly (£1.67-£2/h), so you need to decide whether it is economy or occassional use that is your priority before your fuel purchase.


2. How does an installation of a Bio Fire work?

Imagine you bought a heavy mirror or a large picture frame and you ask someone to hang it. This is exactly the same process as hanging a wall-hung Bio Fire. No installation whatsoever, just make sure it is levelled and use the right size wall-plugs and screws (always provided in the packaging). You need to make sure that the wall you use to hang your fire on is going to stand its weight (this will differ from one model to another, but normally is between 10-27kg) and if necessary strenghten it by adding support at the back. If your fire is freestanding, just position it in the desired location, fill up and light.


3. Can I use a flat TV screens above your fires?


Yes, most fires are safe to use with flat TV screens. You need to check whether your fire has 'enclosed' top to assess suitability. Some new wall-hanging units are open at the top and have glass panel at the front. They are NOT suitable to be put beneath a TV because all the heat goes up, so it would damage your TV. You would need to create a full recess and make sure that there is a thick and secure, non-flammable material between the top of the fire and the TV or consider alternative solutions.


3. Can I use a "ceramic sponge" or "cotton wool" advertised online as a way of extending the flame?


We do not recommend use of any accessory which goes inside the container. Beside the fact that we have not found separately-sold accessory of this sort which actually does work, first and most important risk is the possibility of small cinders still glowing at the base of the fire when the flame has already gone out on the surface. If this happens and you are refilling your fire, it could potentially be very dangerous as the pouring fuel could quickly ignite. In any case, ALWAYS check for cinders when refilling your Bio Fuel or Gel fireplace or burner.


4. Are there any legal regulations I have to follow?

In principle there are no legal or other regulations from the building regulations body or elsewhere for mobile decorative fireplaces that run on alcohol. Some work is currently being carried out in order to establish A European Safety Standard for bio fires, however this will take some time. The EU Standard is not a mandatory regulation but it will bring more awarness to the general public and it will create a set of rules for the manufacturers to follow. We are closely monitoring the topic of bio fire regulations and we are doing our best so our products are up to date with the set safety standards. Our fireplaces are also laboratory tested and most of them are using our Small Burner which has received a TUV certification as safe to use according to the instructons. Nevertheless, Bio Fires are to be used - above all - with common sense, so the flame should never be left unattended and the only ventillation you have to have in the room with an ethanol-run fireplace is a window, which you can open if it gets too hot.


5. How does a bio fireplace work without a flue?

The bio fireplaces run on bio alcohol; an alcohol specially designed for our fireplaces that has been repeatedly cleaned and filtered. It is made of various raw materials such as potatoes, maize and molasses. The combustion of this biological alcohol in the stainless steel fuel container is so clean that it requires no extraction.

6. What is the difference between Gel Fire and Bio Ethanol fire?


Gel fires are an old fashioned version of alcohol fireplaces. At Bio Fires we sell both Gel and Ethanol-fuelled fireplaces, however vast majority of the models are now running on Bio Ethanol and only some small table top burners still use gel. The main difference between the two type of fuels is the fact that they require different types of containers and Bio Ethanol is a much cleaner burning product. Read more in our Gel & Bio Ethanol section.


7. What exactly is bio fuel?

Bio fuel is made up of pure ethyl alcohol that is denatured. This alcohol is unusable for consumption. Natural substances are added to the alcohol so that the flames have a natural, warm, yellow-red colour.


8. What is the emission?

Composed almost completely of water vapour and CO2 (carbon dioxide), the amount of CO2 emission from combustion of ethanol is comparable to human breath. The other components emitted are negligible in quantity well under any limits. The other hazardous substances of combustion such as monoxide, stockoxide and aldehyde are not released until a combustion temperature of 700°C; the temperature of the bio fireplaces is under 400°C.


9. Are the fires tested for safety?


Yes, all our fireplaces are laboratory tested before we put them on the market. As there is no legal regulations, we do not obtain certificates to match any standards (since there aren't any yet), but we are particularly careful about supplying you with a fully safe to use product. The results of our Laboratory Safety Tests are available for you to view, should you wish to do so.



10. Will a room be heated by bio fireplace?

In a way yes. When bio alcohol fireplaces are burning, there is about 3 kWh of ´heat value´ produced in the room. Our fireplaces are not designed purely for heating purposes but mainly as decorative products, nevertheless, when you use the fireplace, you will enjoy a delightful and pleasant warmth. At the same time, the fire will function as a slight humidifier because water is released when fuels that contain alcohol are combusted. This CO2 ´emission´ is neutral because the CO2 released is the same that was absorbed by plants.



11. What must I never do?

Do not spill any fuel when filling the fuel box. If this does happen, remove the fuel meticulously. The fireplace should not be lit until the spilled fuel has completely dried. Never top up the fuel box of a burning bio fireplace. If the fuel box has to be topped up, make sure that the flames are properly extinguished and the box has cooled.

12. How does a bio fireplace function?

Bio fireplaces burn instantly. You fill the fuel box with bio alcohol to the level indicated on the instructions. Use the funnel provided or possibly a measuring jug to pour the fuel. Be very careful not to spill any fuel. Then light the fireplace with a long lighter or a long fireplace match. With Gel Fuel, the flame is instant, while with Bio Ethanol, for the first 5 to 10 minutes the typical blue alcohol flame will appear which will 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 control tool to slide the lid, cutting the oxygen supply and putting the flame out.



13.  Where can I buy replacement Bio Fuel or Gel Fuel?


You can always buy your fuel from us, over the Internet or on the phone. There are other companies selling it, too, but you have to be careful that you buy the right one. Different fuels (especially the cheaper ones available on Internet auctions) may have higher alcohol content and THEY CAN DAMAGE YOUR FIRE or even BE DANGEROUS. The Bio Ethanol fuel we use and design our fires for has 96.6% of ethanol. ALWAYS CALL US IF YOU ARE UNSURE ABOUT YOUR FUEL.


14. Which way should I position the burner within fires containing the Small Burner?


You can put it both ways, whichever is more convenient for you. It will not affect the burning process.


15. How can I clean the lid of Small Burner from any possible Fragrance Oil stains?


If you spill any oil outside the Fragrance Diffuser reservoirs, try not to leave it to dry up on the lid. If the stains are minor, just use hot water and dishwashing liquid, if stains are older and more persistent, you can clean the lid by soaking it in hot (even boiling) soappy water and then slowly but firmly cleanig the stained areas with 'rough' side of dishwashing sponge.
