What size pool heater pump is needed for about a 17000 gallon above ground pool?

For a 17,000-gallon above ground pool, a pool heater pump with a capacity of around 100,000 to 125,000 BTUs is typically recommended. This size will efficiently heat the water while maintaining a comfortable temperature. It's also important to consider the heater's energy source (electric, gas, or solar) and the climate in which it will be used, as these factors can influence heating efficiency and performance. Always consult a professional for specific recommendations based on your pool's needs and local conditions.
