Quick overview
- Lower running cost than gas Heat pump technology moves heat rather than burning fuel, so it draws less energy than natural gas and propane heaters.
- Built for smaller pools Hayward optimized this HeatPro platform for smaller bodies of water, and lists it for pools up to 13,000 gallons.
- Titanium heat exchanger Titanium stands up to constant contact with treated pool water, which is what usually kills a cheaper exchanger.
- Quiet at the pad An efficient rotary compressor paired with a low noise fan keeps the unit unobtrusive while it runs.
- Digital control panel Water temperature is on the display and the settings are adjusted from the front of the cabinet.
- AHRI certified Performance is independently lab tested rather than self reported by the factory.

Product details
The Hayward HeatPro is the heat pump platform Hayward built for smaller pools. Instead of burning fuel, it pulls warmth out of the surrounding air and moves it into the water, which is why its energy requirement sits below what a natural gas or propane heater needs to hold the same temperature.
What it is made of
The heat exchanger is titanium, so the surface in permanent contact with treated pool water resists the corrosion that ends the life of lesser units. Air is moved by a low noise fan in a horizontal discharge cabinet, and the refrigerant side runs on an efficient rotary compressor. The combination is what lets the unit sit near a deck without dominating it.
Running it
A digital control panel on the cabinet shows the current water temperature and holds the settings, so day to day operation is a couple of button presses. Hayward states the platform reaches ideal water temperatures even under harsh conditions, and the unit is AHRI certified with independent lab testing behind the rating.
Before you order
Note that the heating capacity appears two ways in the source data, as 47,000 BTU in the product title and as 50,000 BTU on the HP50HA model listing. Confirm the figure against the data plate and current Hayward documentation if you are matching the unit to a calculated heat load.
