Multiple spray options Built in turbine powers the screen – no batteries. LCD Screen readout water shower flow rate and temperature. The end of the screen changes colour with water flow. <40L green – indicates good water conservation and lower hot water usage saving you energy. 41-59L Orange – above average usage. >60L Red – very high, high water and gas/ electricity usage with high energy bills. Button on the side to change the spray function. 8L/min flow rate. Full flow aerating shower with consistent spray pressure just as good as a conventional shower. Independent testing has shown these shower heads can reduce your hot water bill by 75 per year* and reduce you metered water bill by 60 per year* in a typical property. Lime scale build up prevention with wipe clean rubber nodules. Helps you to reduce your carbon emissions protecting the environment. Excellent value and water/energy saving with performance better than market leading models. Fits onto a standard shower hose, simply screws on, no tools needed.

Air will be inhaled continuously into water stream through the venturi hole to create a mix of water and air, this speeds up the water stream leading to an improvement of the water pressure, meanwhile water would be saved as air takes up half of the space. When water reaches the skin, it explodes automatically giving a pressurized and oxygenised SPA and massage feeling, with an enhanced blood circulation effect, Manufacturer: LOWENERGIE
