Heat Pump

reversible down to -5 ° C

The Nano Action Reversible has nothing to envy of large heat pumps. With its reversible functionality, it cools down the water in your swimming pool just as well as it heats it up. This is particularly useful for small above-ground swimming pools where the water tends to heat up quickly under the action of the sun's rays, causing algae growth on the liner.

With its capacity to operate down to -5 °C, one can comfortably extend the swimming season from Spring to Autumn.

plug & play

With its Plug & Play functionality, the Nano Action can be installed quickly with a simple connection to a power outlet. It does not require any bypass. The 5 meters long cable is equipped with 10 mA differential protection ensuring safe use.

ultra compact

As a heat pump dedicated to small pools and above ground swimming pools, the Nano Action, and its reduced dimensions at 40 cm wide by 39 cm high, knows how to be discreet. This heat pump sits next to the pool and blends right within the decor..

connects to all above ground pools

Compact and packed with functionalities designed for ease of use, the Nano Action heat pump follows closely with the trend of above ground pools that are installed and heat up in just a couple of hours.
