Madimack InverELITE V4 330 33kW Pool Heat Pump
Couldn't load pickup availability
The Madimack InverELITE V4 330 (Madimack model Elite V4 - 330) is a 33kW single-phase inverter pool heat pump with a published COP of up to 20.3. Madimack describes the InverELITE V4 as the world's most efficient and quietest pool heat pump. It combines a twin rotary Mitsubishi DC compressor, a commercial grade centrifugal fan and 3-directional airflow with triple-layer sound insulation, and it operates in air temperatures from -20°C to 43°C. Madimack's warranty runs to 25 years on the heat exchanger.
Who Is the InverELITE V4 330 Suited To?
Pool and spa owners who want the quietest and most efficient heat pump Madimack makes, including owners with neighbours close by or a pool close to living areas. The 33kW is hard wired on a 230V single-phase supply, with a maximum input current of 24.0A and a 30A breaker rating, so it needs a licensed electrician. A published operating range down to -20°C also suits cooler climates and a longer swimming season. It's the largest single-phase size and the eighth of the nine InverELITE V4 sizes: a step up from the 27kW when that's too small. For larger pools still, the 41kW is a 400V three-phase model.

Our Recommendation: Choosing the Right Size
The right heat pump size depends on your pool volume, whether you use a cover, how exposed the pool is to wind and shade, and the temperature you want to hold. A heat pump that's too small will run longer and struggle in cooler weather. Read our Madimack Heat Pump Buying Guide, or send us your pool size and whether you use a cover, and we'll recommend the right size.
