1. What is BTU to Boiler HP Conversion?

Definition: This calculator converts British Thermal Units per hour (BTU/h) to boiler horsepower, a unit of power measurement for boilers.

Purpose: It helps engineers and technicians working with boiler systems to convert between these common power measurement units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( HP \) — Boiler horsepower
• \( Q \) — Heat input rate (BTU/h)

Explanation: One boiler horsepower is defined as the energy rate needed to evaporate 34.5 pounds of water at 212°F in one hour, which equals 33,475 BTU/h.

3. Importance of Boiler HP Calculation

Details: Proper conversion between these units ensures accurate boiler sizing, performance evaluation, and system comparisons.

4. Using the Calculator

Tips: Enter the BTU/h value (must be > 0) to get the equivalent boiler horsepower. The result is displayed with 6 decimal places for precision.

5. Frequently Asked Questions (FAQ)

Q1: Why 33,475 BTU/h equals 1 boiler HP?
A: This is the standardized amount of energy needed to evaporate 34.5 lbs of water at 212°F in one hour.

Q2: How does boiler HP differ from mechanical HP?
A: Boiler HP is about heat energy (33,475 BTU/h), while mechanical HP is about work (550 ft-lb/s or 2,545 BTU/h).

Q3: When would I need this conversion?
A: When comparing boiler specifications, sizing new equipment, or converting between different measurement systems.

Q4: Is this the same as electrical horsepower?
A: No, electrical HP is 746 watts or about 2,545 BTU/h - completely different from boiler HP.

Q5: What's a typical boiler HP rating?
A: Residential boilers might be 5-50 HP, while industrial boilers can be hundreds or thousands of HP.
