What is the Btuh output of an electric heater rated at 15 kW?

511
5,118
51,180
511,800

The correct answer is: 51,180

To determine the Btuh (British thermal units per hour) output of an electric heater rated at 15 kW, it’s important to understand the conversion between kilowatts and BTUs. 1 kilowatt is equivalent to approximately 3,412 BTUs per hour. Therefore, to convert the power rating of the heater from kW to Btuh, you multiply the power rating by this conversion factor. For a heater rated at 15 kW: 15 kW × 3,412 BTU/kW = 51,180 BTUh This conversion shows that the output of the electric heater is indeed 51,180 BTUh, confirming that the answer is correct. This calculation is essential in ensuring proper heating calculations, particularly in assessing the heating needs of residential or commercial spaces. Understanding this conversion can assist in choosing appropriately rated heaters for various applications.
