Smokeless coals provide clean, efficient burning fire for your home fireplace or stove. They are an attractive alternative to traditional coals for those living in smoke control areas or wanting to operate a more environmentally friendly home fire. One particular benefit is with their burn rate being particularly impressive. To understand how long a standard 10kg or a 20kg bag of smokeless coals will last for in a home fire, we need to consider the burn rate and heating capacity of the coals.
We will also consider the size of the fire, burning conditions and the type of fire used. We will examine how each of these factors affects the burn rate and overall duration of the smokeless coals.
10kg Bag of Smokeless Coals
A 10kg bag of smokeless coals is usually enough to fuel a medium-sized home fire for about 3-4 hours. This can vary, depending on the type of fire you are using and the burn conditions.
For example, if you are using a multi-fuel stove with a medium airflow it may take longer to burn the coals. Likewise, if you are using an open fire that produces lots of flames, the coals will burn faster. Generally, you should be able to achieve a 3-4 hour burn rate from a 10kg bag of smokeless coals.
In terms of heating capacity, the 10kg bag of smokeless coals will provide the same amount of heat, regardless of how quickly they burn. The main difference is the length of time the heat will be produced. While the rate of heat generation may differ slightly, the overall effect will be the same – a warm, cosy space in your home.
20kg Bag of Smokeless Coals
A 20kg bag of smokeless coals can provide a comfortable warmth in your home for a significantly longer period of time than the 10kg option – typically around 5-6 hours. This is due to the larger size of the bag, which means more coals in the fire basket and therefore more hours of efficient burning.
Of course, the burning conditions and the type of fire you use will also influence the overall burn rate. If you are using a multi-fuel stove, it may take longer to burn the coals than if you were using an open fire and a higher flame.
Similar to the 10kg bag of smokeless coals, a 20kg bag will deliver the same amount of heat regardless of the burn rate. This means that a 20kg bag of smokeless coals will provide your home with a comfortable warmth for around 5-6 hours – significantly more than the 10kg option.
Conclusion
Smokeless coals are a highly efficient form of solid fuel that are suitable for use in a home fireplace or stove. A 10kg bag of smokeless coals should offer a burn time of around 3-4 hours, while a 20kg bag should offer a burn time of around 5-6 hours. This burn rate may be affected by the type of fire, burning conditions and other factors, but the heating capacity will remain consistent.
When using smokeless coals, it is important to follow all safety guidelines. Make sure you read the instructions on the bag and keep the fire in good condition. This is the best way to ensure the highest level of efficiency and the longest burn time from your smokeless coals.
