With the W'eau Sand Filter Set with Mini Inverter Heat Pump, you choose a complete technical system that allows you to efficiently filter and comfortably heat your pool water. This carefully curated set includes all essential components to immediately create a reliable pool installation. Ideal for above-ground pools and smaller permanent pools where quality, ease of use, and energy efficiency are paramount.
The foundation of this technical set is a powerful W'eau sand filter set. Thanks to the combination of a robust filter vessel and a reliable pool pump, dirt is effectively filtered out of the pool water. In combination with the included filter glass, even finer dirt is captured than with traditional filter sand. As a result, the water stays clear for longer, requires less frequent backwashing, and saves you on water and maintenance.
For a pleasant swimming temperature, the set is equipped with a W'eau Mini Inverter pool heat pump. This compact heat pump automatically adjusts its output to the heating demand, making it quieter and more energy-efficient than a traditional on/off heat pump. This allows you to enjoy a comfortably heated pool for longer at lower energy costs.
To easily connect the heat pump, a Universal Bypass Kit is included. With the three valves, you can precisely regulate how much water flows through the heat pump. This ensures the heat pump always operates under ideal conditions and can be easily shut off for maintenance or winterizing.
In addition, you will receive a set of connection hoses, a protective cover for the heat pump, vibration dampers for quieter operation, and all necessary connection materials to complete the installation.
This complete technical set saves you from having to combine separate parts yourself. All components are matched to each other and together form a reliable and durable solution for years of swimming pleasure.
