W’eau Solar Panel – Sustainable Pool Heating for Pools up to 10,000 Liters
Enjoy warm pool water for longer with the W’eau solar panel! This eco-friendly solar panel uses solar energy to heat your pool in a natural and cost-effective way. Thanks to its compact size (72 x 46 x 11 cm), the panel is ideal for above-ground pools with a capacity of up to 10 m³ (10,000 liters).
How does it work?
The pool water is circulated through the solar collector via hoses, where it is heated by the sun. The heated water then flows back into the pool, allowing the temperature to rise naturally – without additional energy costs.
Easy installation and expansion
The W’eau solar panel features adjustable legs, allowing you to easily tilt and aim the panel toward the sun. This ensures that sunlight is optimally utilized throughout the day. The panel can be quickly connected to the existing pool pump and comes with standard 32/38 mm connections. Want to heat faster and more efficiently? You can connect up to two panels together for greater heating capacity.
Important tips for use
-
Pump capacity: Make sure your pool pump is powerful enough to circulate the water through the panel. A flow rate of up to 10,000 liters per hour is possible, but this requires a pump with sufficient capacity.
-
Be careful with overcapacity: A pump that is too powerful can damage the pipes and the panel, while a pump that is too weak will not provide enough pressure for effective heating. Consult your pump's manual or seek advice to find the right combination.
-
Optimal placement: Place the panel in a sunny spot, preferably facing south, with as little shade as possible during the day.
-
Use in combination with a cover: For the best heating results, use the solar panel together with a solar pool cover so that heat is lost more slowly.
Benefits at a glance
✔ Sustainable and energy-efficient
✔ Easy to install and use
✔ Suitable for pools up to 10,000 liters
✔ Can be connected to a second panel
✔ Adjustable legs for optimal sun orientation

When it is cold outside, the pump heats the water to a pleasant temperature. On warm summer days, the same pump ensures that the water stays refreshingly cool.
