How many BTUs are equivalent to one boiler horsepower?

  1. 14000 BTU

  2. 34000 BTU

  3. 60000 BTU

  4. 75000 BTU

The correct answer is: 34000 BTU

One boiler horsepower is defined as the amount of energy required to raise the temperature of 34.5 pounds of water by one degree Fahrenheit in one hour. This translates to an energy output of approximately 33,475 BTUs per hour. Rounding this figure up for practical purposes, it is often stated as 34,000 BTUs per hour. This conversion is crucial in various calculations related to heating and steam generation, ensuring that systems are appropriately sized based on their thermal output capabilities. The understanding of this conversion allows gas fitters to match boiler capacities with the heating demands of a facility accurately.
