Questions and answers

Is the Hayward HeatPro worth it for a large pool?
At 140,000 BTU it is sized for big in-ground pools up to 140,000 gallons. The 5.7 COP keeps electric running costs low compared with resistance heat. At $5,200 as of November 7, 2026, it is a serious investment that pays back on efficiency over gas or electric heaters.

A heat pump like this moves heat rather than burning fuel, so running costs are usually much lower. Gas heats faster and works in colder air. This unit still heats down to about 40°F, which covers most cool-weather use.
What electrical setup does it need?
It requires 240V at 40 amps maximum breaker and draws about 7.2 kW. That means a dedicated circuit run to the outdoor location. Confirm your panel capacity before buying.
How much space does it need around it?
Plan for 72 inches of vertical clearance and an outdoor spot with good airflow. The unit itself is 44 inches tall, 30.5 inches wide and 33.6 inches deep.
What plumbing connections does it use?
It takes 2-inch to 2-1/2-inch plumbing connections and supports flow up to 75 GPM. Match your pump and piping to that range for best performance.
When is the price lowest?
Pool heat pump prices often dip in late summer and fall as pool season winds down. The current best is $5,200 at AppaeTech Pool Supply as of November 7, 2026; check the price history before buying.
