Key Facts About Bioethanol Fires

  • Real Flames: They burn liquid bioethanol fuel to produce genuine orange flames.
  • No Chimney Needed: No flue, gas line, or hard-wired electricity supply required.
  • Clean Burning: 100% smoke-free, soot-free, and ash-free.
  • Heat Output: They produce real heat (typically 1.5kW-3kW depending on the model).
  • Versatile: Suitable for homes, flats, apartments, conservatories, and commercial spaces.
  • Easy Install: Most models are ‘unbox and go’ or require simple wall mounting.

Are you looking for the warmth and ambience of a real flame but live in a modern flat without a chimney? Or perhaps you want to avoid the installation costs of a gas fire?

Bioethanol fires have surged in popularity across the UK, offering a clean, stylish, and eco-friendly alternative to traditional heating. But how do they work, and are they right for your home?

In this buying guide, the experts at Direct Fireplaces break down everything you need to know about bioethanol fires.


What is a Bioethanol Fire?

A bioethanol fire is a flueless fireplace that burns eco-friendly liquid bioethanol fuel to create real flames without producing smoke, soot, or ash.

Unlike wood burners, which release some particulate matter, or gas fires, which require a flue to vent fumes, bioethanol fires burn completely cleanly. The fuel is a biological alcohol produced by fermenting sugars derived from plants (such as corn, wheat, or sugarcane).

Because the combustion is so clean, there is no need for a chimney. This makes them the ultimate solution for modern new-builds, apartments, or older homes where the chimney has been capped.


How Do Bioethanol Fires Work?

The mechanism inside a bioethanol fire is surprisingly simple, which is why they are so reliable.

  • The Fuel: You pour liquid bioethanol into a dedicated steel burner or ‘trough’ inside the fireplace.
  • Ignition: Using a long lighter, you ignite the fuel.
  • Combustion: The fire doesn’t burn the liquid directly; as the fuel heats up, it releases vapours. These vapours ignite to create the dancing yellow flame.
  • Extinguishing: To stop the fire, you simply use the provided closing tool to shut the lid off the burner, cutting off the oxygen supply.

🔎 Inside a Bioethanol Burner: What Happens When You Light It

When lit, the only by-products are a small amount of water vapour and carbon dioxide (roughly the same amount as burning two candles). There are no toxic fumes, meaning you don’t need a vent pipe.


Are Bioethanol Fires Safe?

Safety is our top priority at Direct Fireplaces. When used according to the manufacturer’s instructions, bioethanol fires are very safe. However, because they involve real naked flames and flammable liquids, you must follow safety protocols.

Safety Checklist:

  • Ventilation: While they don’t need a chimney, they do consume oxygen. Always ensure the room has natural ventilation (like a trickle vent or a slightly open door).
  • Refuelling: Never refill a bioethanol fire while it is lit or hot. This is the golden rule. Always wait for the burner to cool down completely (usually 30-45 minutes) before adding more fuel.
  • Spillage: If you spill fuel while filling, wipe it up immediately before lighting the fire.
  • Quality Matters: We only stock reputable brands like ScandiFlames and Hamlet Stoves that adhere to strict safety standards and feature high-quality steel construction.

Do Bioethanol Fires Give Off Heat?

A common myth is that bioethanol fires are ‘just for show’. This is false.

Do bioethanol fires actually heat a room?

Yes. An average bioethanol fire produces between 1.5kW and 3kW of heat. To put that in perspective:

  • Electric Fire: Usually capped at 2k.
  • Wood-Burner: Usually 5kW+.

While a bioethanol fire might not replace your central heating in the depths of winter, it is an excellent secondary heat source. It is perfect for taking the chill out of a living room in the evening without turning on the whole-house heating.


Types of Bioethanol Fires

At Direct Fireplaces, we stock a wide range of styles to suit any interior.

Wall-Mounted Bioethanol Fires

Ideal for saving floor space and creating a modern ‘hole-in-the-wall’ look without structural work.

  • Best For: Modern living rooms and media walls.

Freestanding Bioethanol Fires

Portable and versatile. You can move these from the living room to the dining room as needed.

  • Best For: Renters and open-plan spaces.

Bioethanol Stoves

Do you love the look of a traditional log burner but don’t have a chimney? This is the solution.

  • Best For: Traditional aesthetic in period homes or cottages.

Tabletop Bioethanol Fires

Small, portable, and affordable. These are great for adding ambience to a coffee table or dining setting.

  • Best For: Gifts and decorative accents.

Where Can You Install a Bioethanol Fire?

Because they require no flue, the installation possibilities are almost endless.

  • Apartments & Flats: The number one choice for high-rise living where gas or wood is impossible.
  • Conservatories: Great for adding warmth to glass rooms that get chilly at night.
  • Dining Rooms: A wall-mounted fire at eye level creates a stunning backdrop for dinner parties.
  • Media Walls: Many customers use built-in bioethanol burners under TVs (ensure non-combustible barriers are used).

Don’t Install In: Small, unventilated bathrooms or sleeping areas without adequate airflow.


Bioethanol Fire Running Costs

Are bioethanol fires expensive to run?

The cost depends on the flame setting and the cost of fuel, which fluctuates.

  • Fuel Cost: Buying in bulk (12 or 24 litres) significantly reduces the price per litre.
  • Burn Time: A standard 1-litre burner typically lasts 3 to 4 hours.
  • Hourly Cost: On average, running a bioethanol fire costs roughly £1.00 to £1.50 per hour.

Compared to electric fires, they can be slightly more expensive to run, but they offer a higher heat output and a genuine flame that electricity cannot perfectly replicate.


Pros and Cons of Bioethanol Fires

To help you decide, here is an honest comparison:

✅ Advantages

  • Real Flame: Genuine dancing fire, not an LED projection.
  • Zero Installation: No chimney, flue, or gas pipe needed.
  • Eco-Friendly: Uses renewable plant-based fuel.
  • Portable: Many models can be moved if you move house.
  • Clean: No ash or soot to clean up.

❌ Limitations

  • Refuelling: You must manually pour fuel (cannot be operated by a remote thermostat like a gas one).
  • Ventilation: Requires a source of fresh air.
  • Running Cost: Can be higher than mains gas.

What to Look for When Buying a Bioethanol Fire

When browsing our Bioethanol Collection, keep these factors in mind:

  • Burner Quality: Look for stainless steel burners. For example, the Hamlet Solution 5 offers a robust steel body.
  • Adjustability: Does the burner have a sliding lid? This allows you to regulate the flame size and fuel consumption, as seen in our ScandiFlames range.
  • Burn Time: Check the capacity. A larger tank means less frequent refuelling.
  • Glass Protection: Many of our wall-mounted units, like the ScandiFlames Texas, come with glass panels to protect the flame from draughts.

Are Bioethanol Fires Eco-Friendly?

Yes. Bioethanol is considered a carbon-neutral fuel source. The CO2 released during combustion is roughly equivalent to the amount absorbed by the plants (corn, sugar cane) while they were growing.

Plus, because they don’t release particulate matter (PM2.5), they don’t have any impact on air quality in urban areas.


Frequently Asked Questions

Do bioethanol fires need a chimney?

How long does bioethanol fuel last?

Typically, 1 litre of fuel will burn for 3 to 4 hours, depending on the airflow and flame setting.
