Couldn't load pickup availability
The Madimack InverECO Plus 90 (Madimack model ECO PLUS 9kW, SKU HPECOPLUS90) is a 9kW single-phase inverter heat pump for heating and cooling your pool or spa. A full stepless DC compressor and inverter fan adjust output to demand, so it runs more quietly and efficiently than an on/off heat pump, with a COP of up to 10.5 on this model. WiFi control is standard, the casing is anti-corrosion ABS suited to high-salt areas, and the titanium heat exchanger carries a 25-year Madimack warranty. Previously listed on our site as the Madimack Invereco 90.
Who Is the InverECO Plus 90 Suited To?
Residential pool and spa owners who want an energy-efficient, quiet heat pump with remote control and the option to cool in summer. It operates in air temperatures from 0°C to 43°C, has reverse-cycle defrost for cooler weather, and has a compact footprint (864 x 359 x 648mm). It's the smallest of the six InverECO Plus sizes, a good starting point for smaller pools and spas; larger pools, or pools without a cover, may need the 13kW or above.

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 InverECO Plus size.
