Why choose the Nano Action Reversible to heat up your small swimming pool

The ideal reversible heat pump for swimming pools up to 35m3.

Even more efficient, the Nano action Reversible outperforms all its rivals thanks to its reversible mode able to operate until -5°C.

With its 32/38mm and 1’’ connectors, it can be connected in just a few seconds to any standard filtration system, be it an above ground or in ground swimming pool, or a spa.

Simply plug in your heat pump and let your swimming pool get warm or cool off.

Designed with the same specifications as a premium heat pump, it features the same efficiency in an ultra compact casing. Its light weight enables anyone to carry it easily.

Heats up and Cools down

The Nano Action Reversible has nothing to envy any to larger heat pump. Thanks to its reversible functionality, the Nano Turbo has the capacity to cool down and heat up the water in your pool. This is particularly useful for small above-ground pools where the water tends to heat up quickly under the action of the sun's rays, with a risk algae spreading on the liner.

Plug & Play

Thanks to its Plug & Play functionality, the Nano Action can be installed quickly by simply plugging it into a mains socket. Depending on the filtration system, it can be connected without a bypass.

The 5-metre cable is fitted with 10 mA differential protection to ensure safe use.

Ultra compact

As a heat pump dedicated to small pools and above-ground pools, the Nano Action knows how to be discreet with its reduced dimensions of 40 cm wide by 39 cm high. It installs next to the swimming pool and blends in with the decor.

Connects to all above ground pools

Compact and equipped with functionalities designed for ease of use, the Nano Action heat pump fits perfectly with the trend of above ground pools which can be installed and heated in just a few hours.
