A number of large shower head companies have come out with "aerator low flow shower heads" that conserve water while creating the illusion of a higher flow of water. High Sierra Showerheads™ achieve a low flow and feel good without resorting to aeration. There are three reasons why that's desirable. First, bacteria, which is present in aerated shower heads that do not fully drain after use, is mixed with water and air the next time you take a shower and is sprayed from the shower head. The bacteria in the air filled spray then becomes airborne and is easily inhaled. For this reason, aerated shower heads are not used in hospitals.
Second, aerated shower heads use more energy to heat the water than non-aerated. That is because the spray of aerated shower heads feels colder than that of non aerated sprays, even though the actual water temperature is initially the same. As a result, the user will increase the temperature of the water heater or the mix of hot water, which in turn uses more energy.
The third reason a conservation-minded individual should be wary of aerated shower heads is their tendency to clog. Air is pulled into aerated shower heads through air ducts. These air ducts are very small and easily clog with mineral deposits in the water. Once plugged, the flow rate of the shower head increases, resulting in an uncomfortable spray and a higher flow which wastes water.
Roger Marty, General Manager of Felton , "The concept of using an aerated showerhead to save water is not new, but the technology behind our device using an aerator insert allows the device to work with existing showers already installed. Our engineers worked with Dr Wu's team to turn the concept into an inexpensive, quality product," he said.
|Please keep in mind that all new faucets since 1994 are restricted to conserve water per EPA code mandates. Older faucets had no restrictions. Beyond intentional flow restriction, new installations can sometimes have reduced flow if the lines are not flushed prior to installation of aerators or shower heads. The flow restrictors required for aerators and shower heads can clog, resulting in greatly reduced flow rates. Remove the aerator or shower head and make sure the flow restrictor is not clogged.|
