Why choose the O’SPA Flow spa heat pump?

Specially designed for spas and Nordic baths, the Poolex O’SPA Flow features a dedicated integrated circulation pump, eliminating the need for any external bypass. Its calibrated flow rate ensures stable circulation and precise thermal regulation, while significantly simplifying installation.

Available in 3 power outputs (3 kW, 5 kW and 7 kW), it allows optimal sizing according to your setup. With a COP up to 5.55, it delivers up to 5.5 times more energy than it consumes and operates year-round thanks to its wide operating range (down to -7°C in heating mode).

The O’SPA Flow combines heating, cooling (chiller down to 2°C) and automatic mode in one compact unit. It ensures fast temperature rise, precise maintenance and the creation of cold baths for recovery or summer use.

With its built-in WiFi and Poolex Cloud, it can be remotely controlled via the mobile app and benefits from OTA updates. Its integrated relay also allows control of the spa’s electric heater, ensuring heating continuity and smart energy optimization when required.

Integrated circulation pump: a solution designed specifically for spas

The O’SPA Flow directly integrates a dedicated circulation pump, specifically sized to meet the hydraulic requirements of spas and Nordic baths.

This design completely eliminates the need for an external bypass, often required in traditional installations. Installation becomes simpler, faster and free from complex adjustments.

Thanks to its constant and perfectly calibrated flow rate, the pump ensures stable circulation to the titanium heat exchanger, providing:

Permanent controlled flow
More precise thermal regulation
Stable performance in all conditions
Reduced installation error risks

With a flow rate adapted to spa volumes (up to 3.00 m³/h depending on the model), the O’SPA Flow offers the perfect balance between circulation, energy efficiency and user comfort.

Heating, cooling and automatic mode: complete thermal control all year round

The O’SPA Flow combines high-efficiency heating, chiller function and an intelligent automatic mode in a single unit, providing complete and precise thermal management of your spa in every season.

It ensures rapid temperature increase, stable and precise maintenance, as well as powerful cooling to create an ice bath down to 2°C.

The Auto mode automatically adjusts operation according to ambient conditions to guarantee perfectly controlled temperature, consistent comfort without manual intervention and optimized energy consumption.

A versatile solution suitable for traditional spas, Nordic baths or sports recovery use.

Smart control via the Poolex app: an intelligent and scalable spa

Thanks to its built-in WiFi, the O’SPA Flow can be remotely controlled via the Poolex mobile app to easily manage temperature and operating modes wherever you are.

From your smartphone, you can precisely set the temperature, activate heating or cooling, select automatic mode and adjust settings in real time.

Connected to the Poolex Cloud, the unit benefits from OTA (Over The Air) updates, ensuring a scalable and continuously optimized system without technical intervention.

Thermal performance meets modern connected technology for total comfort and permanent control.

Compact and premium design: discreet and elegant integration

The O’SPA Flow has been designed to naturally integrate near your spa without compromising the aesthetics of your outdoor space.

With its compact format, clean lines and carefully designed decorative grilles, it blends discreetly into its surroundings while maintaining a modern and premium presence.

Its optimized dimensions allow simplified installation even in limited spaces, positioning close to the spa and harmonious integration into any wellness area.

Performance and design combine to deliver equipment that is both functional and aesthetically refined.

Adaptability and energy efficiency: sized to perform

Available in 3 kW, 5 kW and 7 kW, the O’SPA Flow enables precise sizing according to spa volume, avoiding unnecessary overconsumption.

Under standard conditions (Air 26°C / Water 26°C), it delivers up to 7.10 kW with a COP up to 5.55 — up to 5.5 times more energy delivered than consumed.

Even under more demanding conditions (Air 15°C / Water 38°C), it maintains a COP up to 3.40, ensuring stable efficiency in mid-season and winter.

Its wide operating range allows year-round use: heating down to -7°C, cooling up to 43°C, water heated from 10°C to 40°C and cooled down to 2°C. Thanks to its optimized thermodynamic system and R32 refrigerant, the O’SPA Flow combines adaptability, high performance and thermal stability in all climate conditions.
