Pool Heat Time Calculator

Example Calculation

Let's assume the following values:

• Size of Pool $S$ = 10,000 gallons
• Desired Temperature Rise $t$ = 20 °F
• Heater Output Power $HP$ = 100,000 BTUs/hr

Step 1: Multiply the size of the pool by 8.33 and the desired temperature rise:

$$S \times 8.33 \times t = 10,000 \times 8.33 \times 20 = 1,666,000$$

Step 2: Divide by the heater output power:

$$T = \frac{1,666,000}{100,000} = 16.66 \text{ hours}$$
