1. What is a Heat Pump Heating Capacity Calculator?

Definition: This calculator determines the heating capacity of a heat pump based on its Coefficient of Performance (COP) and power input.

Purpose: It helps HVAC professionals and homeowners estimate the heating output of heat pump systems for proper sizing and efficiency analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Capacity — Heating output (kW)
• COP — Coefficient of Performance (dimensionless)
• Power Input — Electrical power consumption (kW)

Explanation: The COP represents the efficiency of the heat pump (how much heat energy it moves versus electrical energy consumed).

3. Importance of Heating Capacity Calculation

Details: Proper capacity calculation ensures adequate heating for the space, energy efficiency, and prevents system over-sizing or under-sizing.

4. Using the Calculator

Tips: Enter the COP (typically 2-5 for modern heat pumps) and power input in kW. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical COP value?
A: Most modern heat pumps have COP values between 2.5 and 4.5, with higher values indicating better efficiency.

Q2: How do I find my heat pump's COP?
A: Check manufacturer specifications or energy guide labels. COP varies with outdoor temperature.

Q3: Does this include heat loss calculations?
A: No, this calculates raw capacity. For system sizing, consider building heat loss calculations.

Q4: What's the difference between COP and capacity?
A: COP measures efficiency (output/input), while capacity measures absolute heating power output.

Q5: Can I use this for cooling capacity?
A: Yes, but use the cooling COP (often called EER) instead of heating COP for accurate results.
