Protect your technical room and pipework with our anti-freeze units!

If you've opted for active winterisation (letting the filtration run at reduced speed through winter), an anti-freeze unit is your best insurance against weather disasters. If temperatures drop sharply, stagnant water or water flowing too slowly through the pipes can freeze, causing the pipework, filter or pump housing to burst. At Jardiboutique, we offer reliable, precise anti-freeze units to automate the protection of your pool.

The principle is simple: using an outdoor temperature sensor, the unit monitors the ambient air. As soon as the safety threshold is reached (usually set to +1°C or +2°C), the unit forces the filtration pump to start. By creating a permanent water movement, it prevents ice from forming in the hydraulic circuit. It's a minimal investment that saves you from extremely costly plumbing repairs in spring.

Jardiboutique's technical advice: For total reliability, the temperature sensor should be installed outside the technical room, ideally on a north-facing wall sheltered from direct sunlight. Remember to test your unit before the first cold spells arrive by placing the sensor in a glass of ice water to check that the pump contact triggers correctly. It's a simple habit that guarantees your peace of mind all winter long!
