Without a flue, a real flame seems impossible. Yet there is a category of fireplaces designed for exactly this situation. Tenderflame appliances run only on Tenderfuel, dosed through the stainless steel wick. No flue, no gas line and no power socket. Below you read why apartments rarely have a chimney, how a flueless fireplace actually works, which models suit your floor area, and what to arrange with your building association or landlord beforehand.

Fireplace in an apartment without a chimney: why a flue is almost never there
Modern apartments are built airtight and use mechanical ventilation instead of ducts. Adding a flue means drilling through a facade or a load bearing structure, which is expensive and rarely permitted by an owners association. Without an outlet, a wood burner, a pellet stove and a gas fireplace all drop out, however attractive their heat output may be. What remains is a portable solution that does not need to vent flue gases at all.
How a Tenderflame works without a flue
In a Tenderflame the flame burns above a stainless steel wick. Capillary action carries Tenderfuel up to the flame, so only a small amount of fuel is available at any moment. There is no open pool of liquid and no smoke or soot. That is why a chimney is not required, provided the room is ventilated the way you would ventilate while cooking.
Which models suit an apartment
Let the size follow the room rather than the other way around. This split makes the choice easier:
- Up to roughly 60 square metres: table models such as Lotus 10, Lotus 12 or Cafe 18
- Larger living rooms: a bigger table model such as Agni 40, or a freestanding model
- A clean interior with no spare floor space: a wall model hung at eye level
- Rented home: choose something portable, with no drilling and no marks on the wall
- Always keep 1 metre clear above the flame and 60 cm to the sides of textiles
Ventilation in an airtight apartment
A controlled flame uses oxygen and releases water vapour and CO2, just like a cooking flame. In a well insulated apartment that is easy to manage. Work through these steps:
- Before lighting, open a window slightly or turn the mechanical ventilation up one setting.
- Think in air volume: below roughly 50 cubic metres, choose a compact model.
- Do not combine several open flames at once in the same small room.
- Let the ventilation run for another quarter of an hour after you extinguish the flame.
- With a heat recovery system, use setting 2 or higher during use.
Owners association, rental contract and insurance
There is no national ban on portable fireplaces without a fixed connection. An owners association can, however, include rules on open flames or flammable liquids in its house rules, and rental contracts sometimes carry a fire safety clause. Read those passages in advance and inform your contents insurer. A proactive notice costs nothing and prevents discussion if you ever file a claim.
Placement: surface, height and walking routes
Place the fireplace on a level, heat resistant surface such as stone, metal, tempered glass or solid wood with a mat underneath. Avoid spots in a walking route, right next to a curtain or under a hanging cabinet. In small apartments a fixed spot is wiser than moving the fireplace every evening. Only move it once the burner has fully burned out and cooled down.
Choose the model that suits your apartment
Once you know the floor area, your ventilation options and the rules of your owners association or landlord, the choice comes down to size and placement. Always refill when cold, using original Tenderfuel: the wick, flame height, burn time and warranty are matched to it.
Frequently asked questions
Do I need extra ventilation when using a fireplace in an apartment?
Ventilate before, during and after use. A window slightly open, or the mechanical ventilation one setting higher, is usually enough in a normally ventilated apartment.
Does Tenderfuel smell during use?
Tenderfuel is developed for a low odour, stable flame. You may notice something briefly when lighting and extinguishing, but hardly anything while it burns.
Does Tenderflame work with a heat recovery system?
Yes. Run the heat recovery unit at setting 2 or higher during use. It removes CO2 and water vapour in a controlled way without much heat loss.
Should my contents insurer know about it?
It is sensible to tell them. The premium usually stays the same, but a proactive notice prevents discussion if you ever file a claim.
Can the fireplace stand in a semi open kitchen?
Yes, provided it stands stable and at least 100 cm away from cooking flames, extractor airflow and textiles. Do not combine a cooking flame and a decorative flame in a small room without ventilation.
Can my owners association forbid a fireplace?
An owners association can include rules on open flames in its house rules. Read the document and, if in doubt, ask the board for written confirmation.
How much heat does such a fireplace give in an apartment?
Expect warmth close to the flame, not heating for the whole room. A table model does not replace a radiator.
