  1. How much heat will my Imagin biofuel fireplace generate?

    This really depends on few points.....The first one is the situation in which you are using the biofuel fireplace. For example, using a biofuel fireplace outside where there may be wind, will use the fuel more quickly than indoors where there is no wind. If using indoors, our fires will warm a room as a secondary heat source. This means, that whereas it wouldn't be sufficient in extremely cold winter temperatures, it would be very effective in most typical autumn and winter days. The way that our customers typically use the biofuel fireplaces varies a lot, but for example, everyone tells us how great they are on those days when you don't want to heat the whole house, for whatever reason, but just want a lovely real flame in a particular room (dinner party, friends gathering or other social occasion) for a few evenings a week. They are ideal for just "topping up" the heat in a particular room

  2. What is the running cost of a bio ethanol fireplace?

    The cost of running a bioethanol fireplace can be as little as 50p per hour depending on usage and buying appropriate quantities of fuel in bulk.

  3. What is a ventless fireplace?

    A ventless biofuel fireplace is simply a fireplace that does not require a chimney, flue or any other venting duct. If you have a biofuel fireplace and some biofuel, then you have all you need to create a beautiful looking fire. Since no flue or chimney is needed, its much easier and cheaper to install than a more traditional gas or wood fireplace.

  4. How does a bioethanol fire work?

    Bio ethanol fireplaces (also known as biofires) don't require chimneys or flues as the fuel burns without producing smoke or soot. The bioethanol fuel is poured into our double lined stainless steel fuel box (any spillages must be wiped away before lighting) and lit with a firelighter. The flame height can be adjusted by opening or closing the fuel box slightly. Once finished simply slide the shutter over the opening in the fuel box to extinguish the flame. It's that easy ! 

  5. Do i need to have a flue or chimney?

    No costly flues or chimneys are required, as our bio ethanol fireplaces burn cleanly without giving off any smoke or soot !

  6. Does bio ethanol fuel produce smoke or soot ?

    Bioethanol fuel burns with 98% efficiency, so when used correctly it is very clean burning and therefore does not produce any smoke, soot or nasty residues. 

    So what does ethanol produce when burned? Nothing more than carbon dioxide and water. You should never observe any smoke or soot coming out of your bioethanol fireplace.

    Potential Reasons Bioethanol Fireplace Sets Off Smoke Alarm

    In the unlikely event that your smoke or carbon monoxide alarm is triggered whilst using a biofire, please in the first instance always stop using the biofire and check the following:

    • That no stray household debris has accidentally fallen into the fuel box and is thus being burned and emitting smoke. Please wait for the biofire to return to room temperature before checking!
    • That you are using high grade bioethanol fuel specifically developed for bioethanol fireplaces.  Do not use any biofuel that does not clearly state it is formulated for use in bioethanol fireplaces. Also ensure it is at least 96% alcohol as this gives the cleanest and longest usage time.
    • That there are no restrictions to the ethanol fuel burning fully and cleanly. In particular, never cover the opening of the fuelbox with any accessories or other obstructions. This may change the quality of the combustion of the fuel.  
    • That any accessories used on or inside the bio fire have been designed specifically for use in biofires. Whilst we recommend you only use accessories available through our website, we are aware that other products are available and have caused the triggering of some smoke/fire alarms.
  7. What are the disadvantages of bioethanol?

    As with any fuel, there are a few disadvantages of ethanol use that may be helpful to note. These include:

    • Efficiency: Biofuel fires tend not to get as hot as their wood-burning alternatives. They are, however, much more environmentally friendly and often much more attractive.
    • Cost: Biofuel is often a little more expensive than other fuels. However, its environmental and health credentials mean that many people are willing to pay a little extra. Remember to check our store regularly to see if we have any great offers on our bottles of bioethanol!

    What are the risks of using ethanol?

    Our biofires are built with your safety in mind. All fireplaces come with an instruction manual which we strongly advise you to read before using your biofire. Here’s two of the most important points for safe use of a biofire.  

    • The main risk is trying to refuel your fuel box when it is already hot! To ensure that your fireplace remains safe at all times, you should only refuel your burner when it has returned to room temperature. (this can take up to 30 minutes depending on how long it has been used for, the specific model and other room conditions).
    • NEVER try to refuel a warm or hot fuel box with bioethanol.  

    Also, be sure to clean up any spillages created from filling the fuel box before lighting.  As a colourless liquid, it can be difficult to see if you have spilled any fuel, something that could risk the ignition of an uncontrolled flame. Even though our biofuel bottles are specially designed to minimise spills, accidents do happen, so please check for spills before lighting.


  8. Where can I use my bioethanol fireplace?

    For our wall mounted fireplace, just like any fire, you need sufficient wall space with no flammable materials such as soft fabrics, curtains etc within at least a metre. The free standing fireplaces can be used indoors and outdoors but please be mindful that any strong winds will blow the flame in random directions. Also bear in mind that the bio fire is a real flame, so it needs to be positioned in a place where it will not be knocked over. Knocking the bioethanol fire over is extremely dangerous since it is a real flame. Always ensure that the free standing fires are placed on a smooth, even, flat surface. NEVER move the biofuel fireplace whilst lit or with any biofuel inside the fuel box. Always ensure that the unit has cooled completely before moving it. Always ensure that any room you choose to use the bio fire in is well ventilated.

  9. Can I use a biofire outdoors?

    Many of our customers do use their bioethanol fire outdoors, but please remember to position them well away from any flammable items, especially those models that have an open front. There may be an unexpected gust of wind that could cause a fire if the flame touches anything flammable!

    Also whilst there is the same amount of heat generated by ethanol fires when used outdoors as indoors, the space being heated is obviously much larger and therefore the heat level will feel less than when used indoors.  

    So if being considered for outdoor purposes, usage of bioethanol fireplaces outdoors  should be mainly used to create a nice relaxing vibe for your space.

    Advantages of Using Bioethanol Fireplaces Outdoors

    Remember that another advantage of biofires is that since there is no smoke, and no chimney required, our freestanding range can be easily moved between indoors and outdoors.  

    Also, at the end of a pleasant summer evening, there's none of the somewhat overwhelming strong smell of smoke on clothes that some other alternatives leave you with!

  10. What advantages do Imaginfires products have over other manufacturers?

    Our biofires are carefully designed by us, and are exclusive to imaginfires. Our bioethanol fuel boxes are manufactured from a very high grade stainless steel and double lined for additional safety and longevity. The closing mechanism on the fuel box is of a thickness and quality that most other fuel boxes simply do not have. They also have a high grade ceramic fibre lining which helps extend burn time and creates a consistent flame. Many other fuel boxes use a low grade ceramic which quickly wears out and is extremely difficult to replace. Our products are tested to the BS EN16647:2015 safety standard, and we work extremely closely with a cross-European team of Bioethanol Industry specialists to regularly review and improve the standard to keep up with the latest developments in the industry. We're not aware of any other UK company that does that!

  11. How quickly can I expect to be using a bio ethanol fireplace when it arrives?

    Our bioethanol fires are aimed at those of us with little time to waste.... Many of our bio ethanol fires require absolutely no installation. They may only need some very small final assembly but on most of the fireplaces, this will take just a few minutes. may involve  inserting the protective glass into its slot, or putting the fuel box inside the housing. Really easy! Just make sure that any room you use the bio fire in is well ventilated.

  12. Are ethanol fireplaces any good?

    Many people who invest in ethanol fireplaces find them to be excellent additions to their homes. Of course, different types of fireplaces suit different kinds of needs, so it is important to do your research before making any purchases. To help you decide whether an ethanol fireplace would work for you, we’ve put together some pros and cons:


    • You do not need a chimney. There’s no smoke from our biofires, so you don’t need to install a flue or chimney.  This not only makes the installation of a biofire super-quick, it also means you have a wider choice of where you can position them.  
    • Ethanol fires do not produce ash or soot.  This makes them easy and quick to maintain. It also means that any glass on our woodburner range of biofires stays clear, so you will always be able to see the flame.  
    • Ethanol fires are very easy to use. Floorstanding models can be up and running within a few minutes of receiving them, whilst even wall mounted bifores can be attached to your wall very easily (typically less than 1 hour). 
    • Although they are not intended for use as your sole heat source in your home, they will give you a very significant heat output.  This varies between biofire type and how they are used, and where they are located, but as a guide you can expect a heat output of around 3kwh, comparable to an electric heater on  medium setting. If you take a quick look through our Trustpilot reviews, you will see one of the most common customer comments is the surprise of the amount of heat they emit.  
    • Biofires are designed with style and sophistication in mind so they will look great in your home.  We put a lot of thought in to our range of biofires, and focus on developing only those designs that we would be delighted to have in our own homes.  


    • Ethanol fires are not designed to replace your main source of heating.  If you want a heat source for use all day, every day, then we would not suggest using a biofire.   Their primary purpose is for an occasional top-up heat source.  

    • They are not suitable for very small  air tight rooms. We don’t recommend them for use in bedrooms for example. Other types of fireplace may be better suited to this type of room.  

    • They require that the biofuel is topped up.  Although they are extremely easy to set up and use, the exact time needed to refill depends on many factors but you can comfortably assume you will need to do so every 3 to 4 hours. This is usually plenty of time for a pleasant cosy evening, but nevertheless on those days that you want to use them for longer, you will need to refill them (once the fuel box has returned to room temperature).

  13. Are bio ethanol fireplaces suitable for Timber frame houses?

    Our bioethanol fires are designed to be positioned in a ‘standard’ domestic dwelling, so if you have a timber frame home, we suggest you take additional precautions to ensure there is no fire hazard. This includes if you are fitting a wall mounted fireplace, the wall should be able to easily take the weight of the fireplace, and it should be lined with fire-retardant paint or lining.  Please also pay particular attention to ensure there are is no risk the fireplace is left unattended, or can be knocked over.  It should always be positioned where there is no risk of draughts blowing the flame into flammable materials.
