Gas fireplace without chimney - is there such a thing?


Some special fireplace types do not actually need a chimney. In addition to bioethanol fireplaces, this is also a special type of gas fireplace. What advantages this fireplace has, what performance is to be expected, and what additional technical facilities are required, this guide explains.

Fireplaces without chimney

Where there is a fire, there is smoke. Smoke must necessarily be dissipated through a chimney. This applies to practically all stoves. An exception is only the ethanol fireplace - and some special gas fireplaces. You can do without a conventional chimney.

Closed systems

Mainly in the use are gas fireplaces, which are created as closed systems. Additional mechanical ventilation on individual models removes the resulting CO2 to the outside in most of these systems. Thus, no connection to a chimney is necessary for these models.

The advantage of closed fireplace systems with a glass pane is the high efficiency. He is around 70 percent. That's about the same as a classic wood fire. By contrast, open systems only have an efficiency of around 15 percent.

The nominal heat output of closed gas chambers can be different. It is usually between 3 kW and 8 kW.

Natural gas, propane gas or LPG cartridges

The operation can be done with natural gas, propane gas but also with LPG cartridges. An 11 kg LPG cartridge lasts for around 25 hours. An existing natural gas connection is advantageous.

The costs amount to about 60 cents for one hour of burning time and heating power of 6 kW. This is significantly more expensive than conventional heaters or wood combustion systems, but significantly cheaper than ethanol fireplaces.

Tips & Tricks

Ethanol fireplaces are significantly more expensive to operate and offer little heating power but only the fireplace optics with an open fire. But they are often cheaper to buy and free to set up.
