Sustainable design The aerator in the basin versions limits the flow to 5 liters per minute, thus decreasing the water flow without diminishing comfort. This aerator enriches water with air, ensuring perfect functionality and guaranteeing 60% more water savings than class A aerators. This flow restriction meets the most demanding water saving standards, certified by the European Water Label. Energy savings Both Alfa basin models feature Roca’s Cold Start technology, which provides cold water on frontal opening, having to turn the handle to the left to gradually obtain hot water. This mechanism guarantees 45% more energy savings than a conventional faucet*. * Based on annual savings for a family of 4, considering 2 minutes per day of toothbrushing and handwashing 5 times a day.
