  • What is a Bio-Ethanol Fireplace?

    • This style of fireplace is fuelled by bioethanol liquid fuel which is a sustainable energy created from processing plant extracts. No chimney is reqiuired so they are classed as 100% energy efficient and there is no loss of heat output.
    • Bio-ethanol fuel fireplaces are an alternative to a conventional fireplace which would be fuelled by gas, wood or electric.
  • Which Fuel should I Use? Gel or Ethanol?

    • We strongly advise only using liquid bio-ethanol fuel in the fireplaces we supply.
    • Liquid fuel is cleaner burning and does not leave residues in the burner or give off smoke or create smells.
    • Gel fuel looks like syrup and it is advised to only use this in outside fireplaces as it can give off emissions.
  • What are the Positive aspects of this type of Fire?

    • Ease of Installation.
    • No Chimney Required.
    • 100% Energy Efficiency.
    • Provide a Decorative form of heating.
  • What are the Negative aspects of this type of Fire?

    • The must be manually filled with fuel and then lit.
    • Consideration needs to be given to storing of the fuel.
    • Room requires some form of natural ventilation.
  • Do I need a chimney or a flue?

    • Flueless fireplaces do not require a chimney or a flue system.
    • Normal ventilation in the room is sufficient to remove any emissions.
  • What are the running costs?

    • This depends on the burner design and can vary from 30p/hour to £1/hour. Selection of a high quality burner tray is important. Costs can vary depending on fuel quality.

  • What is the heat Output?

    • This depends on the size of the slot in the burner. A larger slot will mean a bigger flame and more heat.
    • Choose the burner you will use wisely as a large burner may seem glamorous however it may provide too much heat for your room.
  • Is there any smoke or smell?

    • The liquid bio-ethanol fuel our fires use is basically alcohol with an inhibitor added to stop it being taken as a drink. Hence there is a slight smell given off but it is harmless.
    • Gel fuel (which looks like syrup)does give off smoke and emissions. This type of fuel should never be used in a burner designed for liquid bio-ethanol fuel and it should only be used outdoors.
  • Are there are any building regulations related to these fireplaces?

    • Ventilation : All fires with a naked flame require some form of ventilation either a wall vent or you can use a window to allow some fresh air into the room.
    • Bio-ethanol fuel fireplaces must be installed and used in line with standard building regulations and clearances to combustible materials observed.
    • Any fireplace opening must be constructed of a suitable non-combustible material.
    • If in doubt contact building control at your local council.
  • More Technical Help:


Are these fireplaces safe?

  • Bio-ethanol fireplaces have been available in the USA for over 20 years and are growing in popularity in the UK.
  • The fireplaces are designed to be as safe as possible, stable and secure – always follow the manufacturers installation and user manual.
  • Normal health and safety is required as normal when dealing with a naked flame and flammable liquids.
  • With all open flamed fires a fire guard should be considered.
  • To ensure your safety, you should only use fuel designed for this style of fireplace.
  • No other chemical or substance should be placed or used in the fireplace burner.
  • Bio-fuel Fires should only be filled with a funnel and to within 15cm of the top of the tray.
  • Bio-fuel Fires should never be moved when hot or lit.
  • Bio-fuel Fires should never be refilled when lit or hot.
  • Special care needs to be taken in handling and storing of the fuel.
  • The fire should only be lit in a well ventilated but a draft free environment.
  • Where can I buy the Fuel?

  • Will a gel fireplace cause condensation on my windows?

    • All naked flames produce some moisture and water vapour when burnt. The quantity produced by bio-fuel is very small however there are many factors in a home which cause condensation and these should be identified. The fire must be used in a room which has adequate ventilation like a window or air vent.
    • Factors which cause condensation in rooms are:
      • Poor Ventilation within the room.
      • Low ambient room temperature due to not using a primary heat source.
      • Cooking and Bathing without sufficient ventilation.
      • Putting Clothes on radiators to dry.
  • How do I install my fireplace?

    • Always read the installation instructions before installing and using a bio-fuel fire.
    • A builder will be required to construct a non-combustible chamber in which to house the burner or fireplace.
    • Installation Instructions are included with the fire.
    • Ensure clearance to combustible materials like curtains are maintained at all times.
