A team of former ETH students from Zurich, Switzerland, developed a water generator system, which can be installed between hose connectors to help reducing waisting one of the most important resources on this planet by tracking your shower habits. Hot water usage for showers is a major source of energy consumption in households.
The Amphiro a1 comes to live on as soon as you turn on your shower and provides real-time information on a large, easy to read display. During operation, it shows (1) water temperature, (2) volume from 0.1 to 1999 liters, and (3) a climate animation. All information is presented per shower to ease the comparison of individual events. The device automatically activates itself in a fraction of a second after the tap is turned on and goes off automatically after three minutes of inactivit.
When the water flow stops, a1 shows (1) the energy efficiency class of the recent shower on a scale from A+ to G- and (2) the shower’s volume in liters alternating with the energy consumption in watt-hours or kilowatt-hours.
At Amphiro’s free online portal, you can see your average shower consumption over time, observe trends, and compare yourself to similar households. It is not necessary to establish an Internet connection; the data is not read out automatically but is transferred manually by entering an efficiency code the device updates and displays after each shower. The online efficiency code contains aggregated information about your last 150 showers.
The Water Power Plant
Amphiro’s generator modules come at a size of less then 2.4 cm3 and provide 250 mW at their operation point. With their dynamic bypass, they allow for powering all electronics modules starting from of 3 l/min on, yet allowing for flow rates of above 22 l/min at a pressure drop below 0.1 MPa. They are extremely silent due to highly optimized turbine geometries. Burst pressure is above 5 MPa. A radial sealing allows for easy integration. No moving parts leave the housing of the generator, making the product fully leakage-proof.
They have a Kickstarter campaign running for the so-called b1, which is accompanied by an app giving insights into the user’s individual water and energy consumption in the shower. Supporting features like target setting and neighborhood comparisons are also available. Amphiro b1 is the perfect product for people who like to know more about their daily water and energy consumption.
The company was founded in 2009 by doctoral candidates of ETH Zurich. From the first day, the team pursued the goal to increase comfort and energy efficiency of one of the most widely used products in the world: faucets. Their mission: By the year 2020, more than 10% of all faucets sold will be equipped with Amphiro technology.
