Astral ECOLite IHP180 Benefits
Efficient inverter performance. The IHP180 automatically adjusts compressor and fan speed based on heating demand, helping maintain stable water temperatures while reducing electricity usage.
Strong heating capacity for larger pools. With up to 18kW heating output under optimal conditions, the IHP180 is well suited to medium and larger residential pools that require faster and more consistent heating performance.
Quiet operation for residential use. Designed for quieter everyday performance, the ECOLite range operates at low sound levels to minimise disruption around pool and entertaining areas.
Built for harsh outdoor conditions. The corrosion-resistant casing and titanium heat exchanger are designed to handle coastal air, humid climates, and chemically treated pool water.
Smart control flexibility. The touchscreen controller offers simple operation, while the optional WiFi module enables remote monitoring and control through the Aquatemp mobile app.
Reduced long-term running costs. Full inverter technology and R32 refrigerant help improve energy efficiency and reduce ongoing heating expenses compared to traditional heating systems.
