The SensaHeat ES Series 24kW is the flagship full DC inverter spa and pool heat pump with WiFi control as standard, built around a Mitsubishi DC compressor and titanium heat exchanger. The top-of-the-range model — sized for the largest residential pools and commercial installations, with the rare advantage of running on single-phase 230V power (no 3-phase upgrade required). Hard-wired install (licensed electrician required). 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

• 24.2kW heating @ 27°C Air / 27°C Water / 80% Humidity — COP 10.8 ~ 6.3 (average 9.2 at 50% speed)
• 16.0kW heating @ 15°C Air / 26°C Water / 70% Humidity — COP 6.6 ~ 4.5 (average 6.2 at 50% speed)
• 8.8kW cooling capacity — reverse cycle for hot-day pool cooling

Recommended For

• Large residential pools up to ~80,000L
• Lap pools, swim training pools, and oversized family pools
• Commercial spas, swim schools, accommodation and hospitality pools
• Year-round operation in any Australian climate — including cooler regional VIC, NSW, and Tasmania

Why Choose SensaHeat ES?

• Single-Phase 230V: Industry-leading — most 24kW pool heat pumps require 3-phase. Significant install savings.
• WiFi App Control as Standard: Monitor temperature, schedules, and modes from anywhere.
• Mitsubishi DC Inverter Compressor: Up to 7x more efficient than fixed-speed heat pumps at part load.
• 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%.
• Quiet Operation: 46.9 ~ 58.7 dB at 1m — drops to 26.9 ~ 38.7 dB at 10m, remarkably low for this capacity.

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)
