How many BTUs does a 25 kW heater produce?

To determine how many BTUs a 25 kW heater produces, it's important to understand the relationship between kilowatts and British Thermal Units (BTUs).

1 kilowatt is equivalent to approximately 3,412 BTUs per hour. To convert kilowatts to BTUs, you would multiply the number of kilowatts by 3,412.

For a heater that operates at 25 kW, the calculation would be:

25 kW × 3,412 BTU/kW = 85,300 BTUs.

Rounding to a practical figure, this means that a 25 kW heater produces about 85,325 BTUs, which aligns with the answer that indicates the heater output is represented accurately within the context of BTU conversion.

This understanding is essential for HVAC professionals as it allows them to calculate heating capacities accurately, ensuring appropriate equipment sizing for residential or commercial heating applications.
