Hayward w3hp21105t Heat Pump 110000 Btu/h

Product Description

The HAYWARD w3hp21105t is a pool heat pump rated at 110,000 BTU/h, designed to heat residential and light-commercial swimming pools. Heat pumps of this type extract heat from ambient air and transfer it to pool water through a refrigerant cycle, delivering energy-efficient heating compared to gas heaters. The w3hp21105t belongs to the Heat Pro W3 product line and is sized for mid-to-large inground pools. Installation is performed by a licensed HVAC technician or pool service professional.

This unit is suited for outdoor installation alongside a pool equipment pad. It is sized for inground pools typically in the range where sustained heating demand requires a high-capacity heat pump. The Heat Pro W3 line is a common choice for residential pool applications where year-round or extended-season heating is needed in moderate to warm climates. Consult local climate data and pool volume calculations to confirm proper sizing before installation.
