This model features a round platform design, heat/cool capability, a durable titanium heat exchanger, and Hayward’s Ultra Gold corrosion-resistant evaporator coil. It is a strong option for pool owners who want dependable temperature control without using natural gas or propane.

Heat and Cool Pool Temperature Control

The W3HP31005T is designed for both heating and cooling pool water. It can help warm the pool during cooler weather and help cool the water during hot conditions, making it a flexible solution for maintaining a more enjoyable swimming temperature.

With 100,000 BTU heating capacity, this model is suitable for many residential pool applications when properly sized and professionally installed.

Efficient Electric Heat Pump Performance

Heat pump technology uses ambient air to help transfer heat into the pool water, making it an energy-conscious alternative to gas heating in suitable climates. The Hayward HeatPro is built to maintain water temperature efficiently and quietly while helping reduce dependence on fuel-based heaters.

Because this is an electric heat pump, it does not require natural gas, propane, combustion air, or gas venting.

Built for Durability and Quiet Operation

The HeatPro W3HP31005T includes a titanium heat exchanger for excellent corrosion resistance, even in challenging pool environments. Hayward’s Ultra Gold evaporator coil adds another layer of durability, especially in coastal or humid climates.

A profiled fan blade helps support high performance with quieter operation, making this unit a practical choice for residential equipment pads.
