Powerful, Efficient Heating for Your Spa

The iNHEAT 9kW Inverter Pro Heat Pump uses advanced inverter technology to provide a highly efficient heating system for hot tubs and swim spas, producing more heat energy with less electricity.

Designed for larger hot tubs and smaller swim spas, it produces up to 13.2 kW of heat for every 1 kW of power consumed, dramatically reducing energy costs.

Quiet and unobtrusive, the brushless motor ensures minimal disturbance. Multiple heating modes allow you to choose fast warming, energy-saving operation, or silent overnight heating for comfortable temperatures whenever you want.

Optional WiFi control and a digital LCD panel give you full control of your heat pump system from anywhere. An automatic defrost feature and included winter cover protect the unit and ensure year-round performance.

We provide trusted advice, guidance, and product support for heat pump installation and maintenance, helping you enjoy a reliable spa heating system all year long.

New R32 Eco Gas

Optional WiFi Control

Control your heat pump system remotely via smart devices, adjusting temperature, heating modes, and monitoring seasonal energy efficiency from anywhere.

Multiple Operating Modes

Choose fast warming for immediate hot water, energy-saving standard operation, or silent overnight heating to maintain comfortable temperatures with lower energy bills.

The built-in defrost function and included winter cover prevent freezing in cold climates, ensuring your heat pump continues to run efficiently year-round.
