To heat a 16x32 pool, which is approximately 512 square feet, you generally need a pool heater with a capacity of 100,000 to 150,000 BTUs, depending on factors like desired temperature increase and climate. One appropriately sized heater is usually sufficient, but if you want faster heating or live in a colder area, you might consider a larger unit or two smaller heaters. Always consult with a pool professional to ensure proper sizing for your specific needs.
