1. What is a Boiler Power Calculator?

Definition: This calculator determines the required boiler power in kilowatts based on the heat output in BTU/hour.

Purpose: It helps HVAC professionals and homeowners properly size boilers for heating systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Boiler power (kilowatts)
• \( Q_{btu} \) — Heat output (BTU/hour)

Explanation: The formula converts British Thermal Units per hour to kilowatts using the conversion factor 3412 BTU/h = 1 kW.

3. Importance of Proper Boiler Sizing

Details: Correct boiler sizing ensures efficient operation, prevents energy waste, and maintains optimal heating performance.

4. Using the Calculator

Tips: Enter the required heat output in BTU/hour. The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the 3412 conversion factor?
A: It's the exact conversion between BTU/hour and kilowatts (1 kW = 3412.142 BTU/h).

Q2: How do I find my heat output requirement?
A: Perform a heat loss calculation for your space or consult HVAC sizing guidelines.

Q3: Should I add a safety factor?
A: Yes, typical practice adds 10-20% to the calculated power for safety margin.

Q4: What's a typical BTU requirement for a house?
A: Average homes need 25-50 BTU per square foot, but this varies by climate.

Q5: Can I use this for commercial boilers?
A: Yes, the formula works for any scale as long as you have accurate BTU requirements.
