WATER-SAVING MIXER TAP
1. push the lever down until it locks : the cold water present in the hot water pipes is quickly directed to an expansion tank. 2. when the hot water reaches the faucet, it causes dilation of the thermostatic element that unlocks the lever, enabling it to return to the neutral position. 3. the user can lift the lever and have hot water in a conventional manner without wasting any cold water. The cold water contained in the expansion tank will be reused automatically.To get hot water quickly, most houses are equipped with a hot water looping and a circulation pump that wastes up to 20% of the house energy consumption. The water-saving mixer tap deliver the hot water faster without any water and energy wasting thanks to an additional output orifice and a thermostatic element that detect the presence of the hot water. For the shower with a backward looping, you can even get into the shower before opening the tap without risking to receive a drop of cold water.
