Key takeaways
- A ventless fireplace needs no chimney or flue - you can install one in any apartment, house or office.
- Two leading technologies: bioethanol (real flame, real heat) and water vapour (cold flame, 100% safe to touch).
- Bioethanol suits people who want genuine fire and warmth; water vapour suits homes with kids and pets, hotels and public spaces.
- Both install in minutes: no renovation, no gas line, no service contracts.
A fireplace used to be an architectural decision: chimney, flue, permits, renovation. A ventless fireplace removes all of that. You unpack it, place it where you want fire, and light it the same evening. Here is how ventless fireplaces work, how the two main technologies compare, and how to pick the right one for your space.
What is a ventless fireplace?
A ventless (or vent-free) fireplace is any fireplace that does not need a chimney or external venting. Instead of burning wood or piped gas and exhausting smoke outside, it either burns a clean fuel that produces no smoke - bioethanol - or creates a flame illusion with no combustion at all - water vapour.
Type 1: Bioethanol fireplaces - real flame, no chimney
Bio ethanol fireplaces burn liquid bioethanol, a renewable plant-based alcohol. The combustion is clean: no smoke, no soot, no ash, just heat and a small amount of water vapour and CO2 (comparable to candles).
- Real fire: genuine, living flames - not a screen or an illusion.
- Real heat: 2-4 kW delivered straight into the room; nothing escapes up a chimney.
- Freedom of placement: freestanding stoves like Arcticon, tabletop fireplaces, or built-in burners for custom fire features.
- Smart control: Planika BEV devices ignite from a remote or app and manage refuelling safety automatically.
Type 2: Water vapour fireplaces - the flame you can touch
A water vapour fireplace creates flames from ultra-fine mist lit by LED light. The effect is strikingly realistic - the "fire" dances, flickers and responds to air movement - but the flame is cold.
- 100% safe: no combustion, no heat, no fumes. Touch the flame - it is mist.
- Unlimited runtime: runs on tap water and electricity, for pennies per evening.
- Any space: ideal for homes with children and pets, hotels, restaurants, offices and anywhere fire regulations are strict.
Bioethanol vs water vapour: which ventless fireplace is right for you?
| Bioethanol | Water vapour | |
|---|---|---|
| Flame | Real fire | Realistic cold illusion |
| Heat output | 2-4 kW (real warmth) | None (ambience only) |
| Safety | Safe when used properly | Absolute - safe to touch |
| Running cost | ~3-5 EUR per evening | Water + electricity, minimal |
| Installation | None - place and light | None - plug and play |
| Best for | Living rooms, terraces, anyone who wants real fire and heat | Kids and pets at home, hotels, offices, public spaces |
Simple rule: if you want warmth and real fire, choose bioethanol. If you want the look of fire with zero risk, choose water vapour. Both live in our indoor fireplaces collection.
Are ventless fireplaces safe?
Water vapour fireplaces are inherently safe - there is no fire. Quality bioethanol fireplaces are safe when two conditions are met: the device has proper safety engineering, and you use fireplace-grade fuel. Planika's BEV technology separates the fuel tank from the flame and burns only vapours, with sensors that block refuelling until the device cools down. Pair it with clean-burning Fanola fuel and ventilate the room occasionally, as you would with candles.
FAQ
Does a ventless fireplace need any installation?
No. Freestanding and tabletop models work out of the box. Built-in burners need a housing but still no chimney, gas line or electricity (bioethanol) beyond a socket (water vapour).
Can I have a ventless fireplace in an apartment?
Yes - that is their main advantage. No landlord-proof renovation, no permits for a flue.
Do ventless fireplaces smell?
A water vapour fireplace has no odour at all. A bioethanol fireplace with quality fuel is odourless while burning; a brief alcohol note may appear at extinguishing.
What about outdoors?
For patios and gardens, see our outdoor fireplaces, fire pit tables and outdoor gas fireplaces - outside, venting is not a constraint, so gas becomes an option too.
Planika has been designing and manufacturing ventless fireplaces for over 20 years, with patented BEV technology used in homes, hotels and restaurants in more than 90 countries.
