The SensaHeat ES Series 13kW is a popular mid-size full DC inverter spa and pool heat pump with WiFi control as standard, built around a Mitsubishi DC compressor and titanium heat exchanger. The sweet-spot model for most Australian spas, plunge pools, and small in-ground pools — connects to a 15A outlet (no hard-wiring required) and delivers strong heating output on single-phase power. 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.

Heating & Cooling Performance

• 13.0kW heating @ 27°C Air / 27°C Water / 80% Humidity — COP 10.8 ~ 6.3 (average 9.2 at 50% speed)
• 9.0kW heating @ 15°C Air / 26°C Water / 70% Humidity — COP 6.2 ~ 4.5 (average 6.0 at 50% speed)
• 5.0kW cooling capacity — reverse cycle for hot-day pool cooling

Recommended For

• Most spas and swim spas — fastest heat-up of the smaller end of the range
• Plunge pools and small in-ground pools up to ~25,000L
• Year-round operation across Melbourne, Sydney, Brisbane, and Perth climates
• Spa retrofit replacing element heaters to slash running costs

• Reverse-Cycle Heating & Cooling: Auto-defrost with stable DC inverter operation.
• Titanium Heat Exchanger: ~40% higher efficiency than standard exchangers, chlorine and salt-water rated.
• R32 Refrigerant: Low-GWP (675, ~30% of R410A), future-proof gas charge.
• Anti-Rust ABS Casing: Built for Australian outdoor weather.
• Soft Start Technology: Reduces startup current draw by up to 70%.

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.

Warranty

• Titanium Heat Exchanger: 25 Years
• Compressor: 3 Years
• Other Parts: 2 Years
• On-Site Labour: 1 Year (T&Cs apply)
