A portable barbecue: a possible additional heat source?
With the arrival of cool evenings, the idea of using a portable barbecue as an additional outdoor heating solution may seem ingenious. Indeed, this device naturally generates heat, which encourages some to stay around it even after cooking. However, it's important to understand that using a barbecue as a heater must be approached with caution. Charcoal, gas, or electric models are not designed for this extended use. Heat radiation is real, but diffusion remains limited in time and space. Therefore, if you're hoping to replace a traditional patio heater with a barbecue, you'll need to carefully assess the technical and safety constraints before embarking on this diversion.
Differences between portable barbecue and outdoor heater
It's important to distinguish between a portable barbecue and a traditional outdoor heater. Heating devices, such as patio heaters or fire pits, are designed to distribute heat evenly and safely. Conversely, a barbecue focuses heat on cooking, with a reduced emitting surface. Furthermore, heating autonomy is limited: once the food is cooked, the fire goes out or the charcoal burns out quickly. In comparison, an outdoor space heater can maintain a constant temperature for several hours. Finally, barbecues, especially those using charcoal or wood, emit fumes that can become unpleasant or even dangerous if poorly ventilated. This makes their use as a heater less practical, especially in semi-enclosed or covered spaces.
The advantages of a portable barbecue as a heat source
Even if it's not designed for this purpose, a portable barbecue can still offer some occasional thermal benefits. For example, during a picnic or camping trip, the heat given off by the embers or flame can provide momentary comfort. This is especially true if you use a charcoal model, which retains heat longer after cooking. In addition, the friendly atmosphere generated around a barbecue, with its light and heat, creates a warm psychological effect. However, it's crucial not to rely solely on this type of heat if the outside temperature is very low or if the event lasts for several hours.
Risks of using a barbecue as a heater
Using a portable barbecue as a space heater outdoors carries several significant risks. The first is the danger of carbon monoxide poisoning, especially if the appliance is used in a poorly ventilated area, such as a covered patio, an enclosed gazebo, or under a tent. Even outdoors, poor air circulation can create a hazardous environment. Burns and fires remain real threats if the appliance is poorly monitored. Finally, there is the potential for premature wear and tear on the barbecue, which is not designed for continuous operation. These are the reasons why manufacturers strongly advise against using it for this purpose, even if it may seem tempting at first glance.
Best practices for safe and punctual use
If you do choose to use a portable barbecue as a spot heat source, certain precautions are essential. First, make sure the appliance is placed on a stable surface, sheltered from the wind, and well away from any flammable materials. Always keep a bucket of water or a fire extinguisher nearby. Avoid use in semi-enclosed areas and ensure continuous ventilation. Never leave the barbecue unattended, even after cooking, as the embers can remain glowing for several hours. To prolong the heat distribution, certain accessories such as firebricks or lids can help, but again, safety must remain the top priority.
Recommended alternatives for outdoor heating
Rather than diverting the use of a portable barbecue , it is often wiser to invest in a suitable outdoor heater. There are plenty of options: designer fire pits, free-standing gas heaters, infrared electric models, etc. These devices are designed for efficient and safe heat distribution, with a much greater autonomy. Some hybrid models even allow you to cook lightly while heating (like braziers-plancha). By opting for a dedicated device, you benefit from much longer-lasting thermal comfort without compromising safety. This does not prevent you from using a barbecue for cooking, then switching to a high-performance heater to extend the evening.
Conclusion: a possible but very restricted use
In conclusion, a portable barbecue can provide additional heat outdoors, but this should only be done exceptionally, occasionally, and with all necessary precautions. It should never replace a proper heating system. For long evenings, low temperatures, or semi-enclosed environments, choose solutions specifically designed for safe heating. Finally, keep in mind that your thermal comfort should never come at the expense of your safety or that of your guests.

FAQ: Portable BBQ and Outdoor Heater
1. Can you use a portable barbecue under a pergola to keep warm?
No, this poses a high risk of carbon monoxide poisoning. Even under a semi-open pergola, ventilation may be insufficient to evacuate the fumes.
2. How long does it stay hot after cooking with a charcoal barbecue?
The heat can persist for between 30 minutes and 1 hour after cooking depending on the type of charcoal used, but it is neither constant nor sufficient to heat a group of people for a long time.
3. What is the best fuel to prolong the heat of the barbecue?
High-quality charcoal or compressed briquettes retain heat longer than conventional wood, but again, this is a temporary heating solution.
Finally, if you're considering using a barbecue on the go, be aware that there are specific considerations to follow depending on the context.
