1. What is a Pool Heat Pump Sizing Calculator?

Definition: This calculator determines the appropriate size (in kW) of a heat pump needed to heat a swimming pool based on volume, desired temperature increase, and heating time.

Purpose: It helps pool owners and professionals select the right-sized heat pump for efficient and effective pool heating.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Size} \) — Required heat pump capacity (kW)
• \( \text{Volume} \) — Pool water volume (cubic meters)
• \( \Delta T \) — Desired temperature increase (Kelvin)
• \( \text{Hours} \) — Desired heating time (hours)

Explanation: The formula calculates the energy needed to heat the pool water by the desired temperature within the specified time frame.

3. Importance of Proper Heat Pump Sizing

Details: Correct sizing ensures energy efficiency, proper heating performance, and prevents equipment strain from undersizing or unnecessary costs from oversizing.

4. Using the Calculator

Tips: Enter your pool volume in cubic meters, desired temperature increase (typically 10-15K for seasonal heating), and your target heating time (default 24 hours).

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate my pool volume?
A: For rectangular pools: Length × Width × Average Depth. For irregular shapes, consult pool specifications or use specialized calculators.

Q2: What's a typical temperature rise for pools?
A: Most pools aim for a 10-15°C (10-15K) rise from the source water temperature to comfortable swimming temperature.

Q3: Does this account for heat loss?
A: This is a basic calculation. For precise sizing, consider adding 20-30% to account for heat loss through evaporation and conduction.

Q4: Can I use this for saltwater pools?
A: Yes, but saltwater pools may require slightly larger heat pumps due to higher specific heat capacity.

Q5: What if I want faster heating?
A: Reduce the "hours" value to see the required heat pump size for faster heating times.
