The SensaHeat ES Series 9kW is a compact full DC inverter spa and pool heat pump with WiFi control as standard, built around a Mitsubishi DC compressor and titanium heat exchanger. The smallest in the range — and the only model that plugs straight into a standard 10A outlet, no electrician required for connection. Ideal for spas, swim spas, and small plunge pools. Backed by Australia's largest OEM spa equipment distribution network — local stock and service across VIC, NSW, QLD, and WA, not the typical drop-shipping experience.

Spa Control System Integration
The SensaHeat ES is a popular retrofit heat pump for spas running Balboa, SpaNet, Gecko (AEware), and Davey control systems — including SpaPro, WWDG, Sapphire, Alpine, Oasis, Vortex, and most Chinese-import spas. Integration uses the optional Sensaheat Heat Pump Relay Controller (DT-1071021) for spa-controller-driven heating. For standalone pool installs, the Dontek / Sensaheat Universal Heat Pump Controller (J-Box / MJ Box / Intelliheat) provides full filtration and heating automation. Common spare parts — flow switches, water temperature sensors, controllers, capacitors, and PI/ES union gaskets — are held locally in stock for fast turnaround on repairs.
