1. What is a Heat Pump Pool Size Calculator?

Definition: This calculator estimates the required size of a heat pump for a swimming pool based on pool volume, desired temperature increase, and heat pump efficiency.

Purpose: It helps pool owners and professionals determine the appropriate heat pump capacity for efficient pool heating.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Size} \) — Required heat pump capacity (kW)
• \( \text{Volume} \) — Pool volume (cubic meters)
• \( \Delta T \) — Desired temperature increase (Kelvin)
• \( \text{COP} \) — Coefficient of Performance (heat pump efficiency)

Explanation: The formula calculates the energy needed to heat the pool volume by the desired temperature difference, adjusted for the heat pump's efficiency and a 24-hour heating period.

3. Importance of Proper Heat Pump Sizing

Details: Correct sizing ensures efficient operation, prevents energy waste, and maintains comfortable pool temperatures.

4. Using the Calculator

Tips: Enter the pool volume in cubic meters, desired temperature increase in Kelvin (1°C = 1K), and COP (default 5.0 for modern heat pumps). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is COP in heat pumps?
A: COP (Coefficient of Performance) measures heat pump efficiency - higher values mean more efficient heating.

Q2: What's a typical COP value?
A: Modern heat pumps typically have COP values between 4.0 and 6.0 depending on conditions.

Q3: How do I find my pool volume?
A: Multiply length × width × average depth (in meters) for rectangular pools. Use our Pool Volume Calculator for irregular shapes.

Q4: What ΔT should I use?
A: Typical values are 10-15K for heating pool water from ambient to comfortable swimming temperature.

Q5: Why the 24-hour factor?
A: This assumes you want to heat the pool within 24 hours. For faster heating, you'll need a larger heat pump.
