1. What is a Pool Heat Pump Sizing Calculator?

Definition: This calculator estimates the required heat pump size (in kW) for a swimming pool based on pool volume and desired temperature rise.

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( kW \) — Heat pump size (kilowatts)
• \( V \) — Pool volume (cubic meters)
• \( \Delta T \) — Desired temperature rise (°C)
• 0.00116 — Conversion factor (kW·h per m³ per °C)

Explanation: The formula calculates the energy required to heat the specified volume of water by the desired temperature difference.

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 and the desired temperature rise in degrees Celsius. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my pool volume?
A: Multiply length × width × average depth (all in meters) for rectangular pools. For irregular shapes, consult pool specifications.

Q2: What's a typical temperature rise for pools?
A: Most systems are designed for 10-15°C rise, but this depends on climate and desired water temperature.

Q3: Should I round up the calculated kW size?
A: Yes, it's recommended to round up to the nearest available heat pump size for better performance.

Q4: Does this account for heat loss?
A: This is a basic calculation. For precise sizing, consider heat loss factors like wind exposure and pool covers.

Q5: Can I use this for saltwater pools?
A: Yes, but saltwater may require slightly more powerful units (add 10-15% to the calculated size).
