Pool Heat Pump Runtime Calculator - Heat Efficiency Guide
Predict exactly how many hours your pool heat pump needs to run to reach your target temperature. Factors in ambient air temperature and COP.
How Ambient Temp Affects HP
Heat pumps do not create heatΠ²Πβthey move it from the air into the water. If the air is cold (below 50ΠΒ°F), there is very little heat to move, causing the **COP (Coefficient of Performance)** to drop. A heat pump that is 110,000 BTU at 80ΠΒ°F air may only produce 70,000 BTU at 50ΠΒ°F air.
Pro Tip: Run your heat pump during the warmest part of the day (10 AM to 6 PM) to maximize efficiency and shorten the runtime.
Frequently Asked Questions
What is COP?
COP stands for Coefficient of Performance. A COP of 5.0 means for every $1 of electricity you put in, you get $5 worth of heat out. Most heat pumps range from 3.0 to 6.5 depending on air temp.
Will it work in the rain?
Yes, rain doesn't significantly impact performance. However, high humidity actually *helps* heat pumps by providing more thermal energy in the air.
