1. What is BTU Calculation?

BTU (British Thermal Unit) calculation helps determine the appropriate heat pump size for a 1500 square foot home. Proper sizing ensures efficient heating and cooling while minimizing energy costs.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• 1500 — Square footage of the home
• Factor — BTU per square foot (typically 20-30 BTU/sq ft)

Explanation: The calculation provides an estimate of the heat pump capacity needed to effectively heat and cool a 1500 sq ft home.

3. Importance of Proper Sizing

Details: Correct heat pump sizing is crucial for energy efficiency, comfort, and system longevity. An undersized unit will struggle to maintain temperature, while an oversized unit will short cycle, reducing efficiency.

4. Using the Calculator

Tips: Enter the BTU factor (typically between 20-30 BTU per square foot). The calculator will estimate the total BTU requirement for a 1500 sq ft home.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect BTU requirements?
A: Climate, insulation quality, window efficiency, ceiling height, and home orientation all impact BTU needs.

Q2: What's the typical BTU range for 1500 sq ft?
A: Typically 30,000–45,000 BTU (20-30 BTU/sq ft × 1500 sq ft).

Q3: Should I always choose the highest BTU?
A: No, oversizing can be as problematic as undersizing. Consult an HVAC professional for precise sizing.

Q4: How does climate affect the factor?
A: Colder climates may need 25-30 BTU/sq ft, moderate climates 20-25 BTU/sq ft.

Q5: What about heat pump efficiency ratings?
A: While BTU measures capacity, also consider SEER (cooling) and HSPF (heating) ratings for efficiency.
