1. What is a BTU Calculator for Heat Pump?

Definition: This calculator estimates the effective heating capacity (in BTU/h) of a heat pump based on its power consumption and efficiency.

Purpose: It helps HVAC professionals and homeowners understand the actual heating performance of heat pump systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( BTU \) — Heating capacity (BTU per hour)
• \( kW \) — Power input (kilowatts)
• \( COP \) — Coefficient of Performance (dimensionless)
• \( 3412 \) — Conversion factor (BTU per kW)

Explanation: The formula accounts for both the electrical energy input and the heat pump's efficiency in transferring heat.

3. Importance of BTU Calculation for Heat Pumps

Details: Proper BTU estimation ensures correct system sizing, energy efficiency, and optimal performance in different climate conditions.

4. Using the Calculator

Tips: Enter the heat pump's power consumption in kW and its COP (default 3.5 for modern systems). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is COP in heat pumps?
A: COP (Coefficient of Performance) measures efficiency - the ratio of heat output to electrical energy input.

Q2: What's a typical COP value?
A: Modern heat pumps typically have COP values between 3.0-4.0, but this varies with temperature conditions.

Q3: Why 3412 in the formula?
A: This is the conversion factor from kW to BTU/h (1 kW = 3412 BTU/h).

Q4: How do I find my heat pump's COP?
A: Check manufacturer specifications or performance charts that show COP at different temperatures.

Q5: Does this work for cooling mode?
A: For cooling, use EER instead of COP (BTU = kW × 3412 × EER/3.412).
