How many btu's is a house fire?

The heat output of a house fire can vary significantly depending on factors like the size of the fire, materials burning, and ventilation. A typical house fire can range from about 1,000,000 to over 2,000,000 BTUs per hour. In larger fires or those involving synthetic materials, the BTU output can be even higher, potentially reaching 10,000,000 BTUs or more. Overall, the intensity and duration of the fire largely dictate the total BTUs produced.
