1. What is a Heat Pump Heating Capacity Calculator?

Definition: This calculator estimates the heating capacity (heat output) of a heat pump based on its power input and coefficient of performance.

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Heat output (watts)
• \( P \) — Power input (watts)
• \( COP \) — Coefficient of Performance (unitless)

Explanation: The power input is multiplied by the COP to determine the heat output. Higher COP values indicate more efficient heat pumps.

3. Importance of Heat Pump Capacity Calculation

Details: Proper capacity estimation ensures adequate heating for spaces, energy efficiency, and proper system sizing.

4. Using the Calculator

Tips: Enter the power input in watts and the COP (default 3.0). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical COP value?
A: Modern heat pumps typically have COP values between 2.5 and 5.0, with higher values indicating better efficiency.

Q2: How do I find the power input?
A: Check the heat pump's specifications or measure the electrical power consumption.

Q3: Does this work for cooling capacity too?
A: Yes, but use the Energy Efficiency Ratio (EER) instead of COP for cooling calculations.

Q4: What affects COP values?
A: Outdoor temperature, system design, and heat pump technology all influence COP.

Q5: How can I improve my heat pump's COP?
A: Regular maintenance, proper sizing, and using in moderate climates can improve COP.
