1. What is a Swimming Pool Heat Calculator?

Definition: This calculator estimates the heat loss or gain of a swimming pool based on surface area, evaporation rate, and conduction.

Purpose: It helps pool owners and maintenance professionals determine heating requirements and energy costs for pool maintenance.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Heat \) — Total heat loss or gain (Watts)
• \( Surface Area \) — Pool surface area (square meters)
• \( Evaporation \) — Evaporation rate (Watts per square meter)
• \( Conduction \) — Heat loss through conduction (Watts)

Explanation: The surface area multiplied by evaporation rate gives evaporative heat loss, then conduction heat loss is added.

3. Importance of Pool Heat Calculation

Details: Proper heat calculation ensures comfortable water temperature, efficient heater sizing, and accurate energy cost estimation.

4. Using the Calculator

Tips: Enter the pool surface area in m², evaporation rate (default 100 W/m²), and conduction (default 500 W). Surface area must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical evaporation rate for pools?
A: Outdoor pools typically lose 100-150 W/m² to evaporation, depending on wind and humidity.

Q2: How do I find my pool's surface area?
A: For rectangular pools: length × width. For circular pools: π × radius².

Q3: What affects conduction heat loss?
A: Water-ground temperature difference, pool insulation, and surrounding air temperature.

Q4: Should I consider solar gain in this calculation?
A: This calculator shows heat loss. For net heat change, subtract solar gain from the result.

Q5: How can I reduce pool heat loss?
A: Use pool covers, windbreaks, and proper insulation to minimize evaporation and conduction.
