Inground Pool Heater Calculator
FAQs
How do you calculate how much heater you need for a pool? To estimate the size of the heater you need for your pool, you’ll need to consider factors like the pool’s volume (in gallons or cubic feet), desired temperature increase, ambient temperature, and insulation. A rough estimate is to use a pool heater with 50,000 BTUs per 10,000 gallons of pool water. However, it’s best to consult with a pool professional for a more accurate calculation.
