Product Overview

The Hayward HeatPro W3HP50HA2 is a 50,000 BTU heat/cool pool heat pump designed to provide efficient temperature control for above-ground pools and smaller in-ground pools. Built on Hayward’s HeatPro platform, this unit can both heat and cool pool water to help maintain a comfortable set temperature through changing weather conditions.

With a durable titanium heat exchanger, corrosion-resistant evaporator coil, quiet side-air operation, and easy-to-read digital display, the W3HP50HA2 is a practical solution for pool owners who want energy-conscious water temperature control without relying on gas heating.

Heat and Cool Temperature Control

Unlike heat-only pool equipment, the Hayward W3HP50HA2 offers heat and cool operation, allowing it to warm pool water during cooler periods and help cool water when temperatures rise. This makes it a flexible option for maintaining a more consistent and comfortable swimming environment.

Its 50,000 BTU heating capacity is well suited for smaller pool applications where efficient temperature control is desired.

Built for Durability and Quiet Operation

The HeatPro W3HP50HA2 is designed with long-term outdoor performance in mind. A titanium heat exchanger helps provide strong corrosion protection, while Hayward’s Ultra Gold corrosion-resistant evaporator coil supports durability in demanding environments, including coastal or humid areas.

The profiled fan blade and efficient compressor design help support quieter operation, making this heat pump a strong choice for residential pool equipment pads.

Product Benefits

Heat and Cool Flexibility

The W3HP50HA2 can help warm pool water when conditions are cooler and cool pool water when temperatures are too warm, supporting better comfort throughout the swim season.

Energy-Conscious Operation

Heat pump technology uses ambient air to help transfer heat into the pool water, making it an efficient alternative to traditional gas heating in the right climate and installation conditions.

Corrosion-Resistant Construction

The titanium heat exchanger and corrosion-resistant evaporator coil help protect the unit from harsh pool environments, supporting long-term durability.

Quiet Residential Performance

The profiled fan blade and efficient design help reduce operating noise compared with many traditional heating solutions.

Easy User Control

The digital display allows pool owners to view and adjust settings more easily for convenient pool temperature management.
