1. What Is Pool Heat Pump Sizing?

Pool heat pump sizing determines the appropriate heating capacity (in kW) required to efficiently heat your swimming pool based on volume, desired temperature rise, specific heat factor, and heating time.

2. How Does The Calculator Work?

The calculator uses the formula:

\[ Size = \frac{Volume \times Temperature\ Rise \times Factor}{Hours} \]

Where:

\( Volume \) — Pool volume in cubic meters (m³)
\( Temperature\ Rise \) — Desired temperature increase in degrees Celsius (°C)
\( Factor \) — Specific heat factor (typically 1.16 kJ/kg·K for water)
\( Hours \) — Desired heating time in hours (h)

Explanation: The formula calculates the required heating power based on the energy needed to raise the pool temperature by the specified amount within the given time frame.

3. Importance Of Proper Sizing

Details: Correctly sizing your pool heat pump ensures efficient operation, optimal performance, energy savings, and extends the equipment's lifespan. Undersized units struggle to maintain temperature while oversized units cycle frequently, reducing efficiency.

4. Using The Calculator

Tips: Enter pool volume in cubic meters, desired temperature rise in °C, specific heat factor (default 1.16 for water), and desired heating time in hours. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical factor value for water?
A: The specific heat capacity of water is approximately 1.16 kJ/kg·K, which is the default value used in the calculator.

Q2: How do I calculate my pool volume?
A: For rectangular pools: Length × Width × Average Depth. For circular pools: π × Radius² × Average Depth. Measurements should be in meters for m³ calculation.

Q3: What is a reasonable temperature rise for pools?
A: Typically 2-5°C above ambient temperature, but this depends on personal preference and climate conditions.

Q4: How many hours should I set for heating?
A: Most systems are designed to heat pools over 24-48 hours for optimal efficiency, but this can vary based on your usage patterns.

Q5: Does this calculation account for heat loss?
A: This is a basic calculation that provides the theoretical heating requirement. Actual sizing should consider additional factors like evaporation, wind exposure, and insulation.
