Pool Heat Pump Sizing Calculator
Calculate the required heat pump size to heat your swimming pool efficiently
About this calculator
This Pool Heat Pump Sizing Calculator helps you determine the optimal heat pump capacity needed to efficiently heat your swimming pool. By considering factors like pool volume, desired temperature, climate conditions, and pool cover usage, it calculates the BTU requirements for your specific setup. Using the right-sized heat pump ensures energy efficiency, cost savings, and comfortable swimming temperatures year-round.
How to use
Enter your pool dimensions (length, width, depth) or total gallons, select your desired water temperature, and input your location's average temperature. Include additional factors like pool cover usage and wind exposure. The calculator will recommend the appropriate heat pump size in BTUs for efficient heating performance.
Frequently asked questions
How do I know what size heat pump I need?
Heat pump size depends on pool volume, temperature differential, climate, and heat loss factors. Generally, you need 50-100 BTU per hour per square foot of pool surface.
Should I oversize my pool heat pump?
Slight oversizing (10-15%) can improve efficiency and reduce heating time, but significant oversizing wastes energy and increases costs without proportional benefits.
Do pool covers affect heat pump sizing?
Yes, pool covers reduce heat loss by 50-70%, allowing you to choose a smaller, more efficient heat pump while maintaining desired temperatures.
