Why Choose the I‑PAC PRO Heat Pump?
✅ Energy-Saving Inverter Technology
The I‑PAC PRO uses advanced inverter control to precisely match energy output to your pool’s heating demand. Unlike traditional on/off units, this ensures smoother operation, lower energy bills, and extended equipment lifespan.
❄️ Year-Round Performance from –20 °C to +43 °C
Whether you're swimming through winter or cooling off in summer, the I‑PAC PRO performs reliably across extreme temperatures, making it ideal for UK weather conditions and beyond.
🌍 Eco-Friendly with R32 Refrigerant
The I‑PAC PRO uses R32 refrigerant, which offers improved efficiency and a lower Global Warming Potential (GWP) than older refrigerants - helping you reduce your environmental impact while staying compliant with EU F-Gas regulations.
🔊 Whisper-Quiet Operation
Thanks to its variable-speed fan and compressor and it's Silence Mode the I-Pac Pro is perfect for noise-sensitive environments like residential gardens, hotels, and wellness centres.
📲 Smart Wi-Fi Control
Manage your heat pump from anywhere with the built-in Wi‑Fi module. Set temperatures, adjust modes, and receive live diagnostics - all from your phone or tablet.
🔧 Built for Durability
The I‑PAC PRO features a titanium heat exchanger, corrosion-resistant casing, and vibration-dampening mounts. It’s built to handle the elements and keep working reliably for years to come.
What’s Included with the I‑PAC PRO?
Every unit comes ready to install, complete with:
5-Year Comprehensive Warranty – No Gimmicks, Just Coverage
