Running Costs & Facts

First and most important: THERE IS NO UNIVERSAL ANSWER. Each fireplace is different and both, heat outcome and fuel usage, depend strictly on the type of burner used in the fireplace.

Our estimates: GENERAL IDEA – approx. 80p to £1.45/h for a proper fireplace container (any fireplace with our standard 1.3 L Small Burner fuelbox)

Facts about our Small Bio Burner (featured in most of our wall-mounted and freestanding fireplaces):

  • burning time: 3-6 hours per refill.
  • one refill takes: from 1 L up to 1.3 L of bio ethanol fuel.
  • effective running cost: £0.80-£1.45 per hour (based on buying fuel in bulk, 18 L for £79.99).
  • heat output: 3 kW or slightly above.
  • flame regulation: yes, by sliding the lid with a control tool (included).
  • flue needed: no.
  • fumes or smoke produced: none (if flame is not obstructed).
  • smell: virtually none (it is a real flame, so you will smell it when you enter a room as nothing that burns can be completely odourless, but the scent is barely present and does not bother 99.9% of people).
  • do I need any ventilation: yes – a window which you can open for 5 minutes after having the fire on for a couple of hours.
  • can I use bio fuel bought elsewhere? Yes, but you must make sure it is the right one, with ethanol content not greater than 96.6% and designed especially for fireplaces. Remember that you get what you pay for – cheaper brands may produce smell when burning. Also, be very wary of buying your fuel in 5 L containers. In fact, although it is cheaper, the weight of it makes it hard to fill up precisely and you are much more likely to spill the fuel. Never light a container that has been overfilled.
  • can I use Aura Fragrance Oil with this burner? Yes, the Small Bio Burner is fitted with a dedicated fragrance diffuser.
  • can I use gellified fuel with it? No, because you cannot wash the burner and gel leaves residue.
  • does the top of container discolour after time? Slightly, the flame is real so the top of the container will eventually tarnish a bit; this is completely normal and cannot be prevented.

Facts about our Regulating Bio Container (50) (most common choice for designing and building your own DIY fireplace):

  • burning time: 3.5-7 hours per refill.
  • one refill takes: 2 L of bio ethanol fuel.
  • effective running cost: approx. under £3 per hour (based on buying fuel in bulk, 18 L for £79.99).
  • heat output: 3-4 kW.
  • flame regulation: regulating lid and tool.
  • flue needed: no.
  • fumes or smoke produced: none (if flame is not obstructed).
  • smell: virtually none (it is a real flame, so you will smell it when you enter a room as nothing that burns can be completely odourless, but the scent is barely present and does not bother 99.9% of people).
  • do I need any ventilation? Yes – a window which you can open but nothing more. Also, your room size is not smaller than the estimated recommended room size (approx. 24 m2 with a ceiling height of 2.4 m). If your room size does not meet the overall requirements, air flow can be improved by opening a door or window frequently. Or you can regulate the flame and burn the fireplace for less than 3.5 hours (at a time) on full opening and less than 7 hours (at a time) when regulated.
