Poolex Silent Max – Fi 155 Inverter Heat Pump – with Wi-Fi

Ultra-quiet, energy-efficient pool heating and cooling with smart Wi-Fi control.

Product Overview

The Poolex Silent Max Fi 155 combines Full Inverter technology with rear ventilation to deliver ultra-quiet, energy-efficient heating and cooling for your pool. The inverter system continuously adapts to your pool’s set temperature, providing energy savings of up to 35% compared to traditional on/off heat pumps.

Thanks to rear ventilation, operational noise is reduced to just 20 dB(A) at 10 metres, making it one of the quietest heat pumps available. Built with a Toshiba compressor and Twisted Tech Titanium heat exchanger, the Fi 155 is durable, corrosion-resistant, and suitable for chlorine and saltwater pools.

Control is simple via the Poolex app, available on iOS and Android, allowing remote adjustment of temperature and operating modes.
