# Dusar showerao separations
The Dusar showerao Separations (DSS) is a system of separating the hot and cold water used in showers. It was developed by the United States Department of Energy's Office of Water as part of its Advanced Research Projects Agency –Energy (ARPA-E) program, which supports research and development projects that are deemed to be high risk but potentially beneficial to society. The goal of the project was to develop a new technology for use with existing plumbing systems, rather than replacing them.

## History Dusar showerao separations
In the early 1980s, the U.S. Department of Energy began an effort to find ways to improve energy efficiency in residential buildings. One of their goals was to reduce the amount of hot or cold water used per shower. They also wanted to make sure that the new technologies would not require major changes to building codes, so they could be easily adopted. To meet these objectives, they decided to focus on developing a new type of showerhead instead of trying to change how people washed themselves.

In 1983, the DOE awarded a contract to General Electric Company to design and build a prototype of a new showerhead. This device consisted of two separate nozzles: one for the hot water and another for the cold water. A valve controlled the flow from each nozzle. The idea behind this design was that if there were problems with either of the nozzles, the user could turn off only the affected nozzle. This way, the other nozzle would still provide some water pressure.

In 1984, GE delivered the first version of the prototype to the DOE. After testing, the DOE found that the prototype worked well. However, it did have several limitations. For example, the valves controlling the flow rate of the hot and cold water had to be adjusted manually. Also, when the user turned off both nozzles at once, the showerhead stopped working altogether. Finally, the prototype required the installation of special pipes inside the wall. These pipes were needed because the prototype was designed to work with standard plumbing systems.

In 1985, the DOE selected GE to continue designing and manufacturing the final product. The company agreed to do so under strict conditions. First, the new showerhead had to be able to replace any current showerhead without requiring modifications to the building code. Second, it had to be easy to install. Third, it had to be reliable and durable. Fourth, it should cost less than $100. And finally, it had to be available within three years.

GE continued to refine the design until 1987. That year, the company released the DSS1 model showerhead. It was the first commercially available showerhead that separated the hot and cold water. At the time, most showerheads combined the hot and cold water into a single stream.

The DSS1 model had many advantages over previous designs. For example, it automatically shuts off both nozzles whenever the user turns off one of them. Another advantage was that the user could control the temperature of the water flowing through the nozzles independently. This allowed the user to adjust the temperature of the water coming out of each nozzle individually. In addition, the DSS1 model met all four of the DOE’s requirements. It replaced existing showerheads, it was easy to install, it was relatively inexpensive, and it was available within three years. By 1990, more than 50 million DSS1 models had been sold worldwide.

Since then, the DSS2 model has become the industry standard. It is now manufactured by Kohler Co., Inc. (Kohler), and it is widely recognized as being among the best showerheads available.

## Benefits of Dusar showerao separations
The Dusar showerao separations system offers several benefits. First, it allows users to control the temperature of the hot and cold streams separately. This feature makes it possible to create different types of showers. For example, a person can use warm water to rinse his or her hair while using cool water to wash his or her body.

Second, the Dusar showerao separations system provides a greater variety of options than older showerheads. For example, the user can choose between a fixed spray pattern and an oscillating spray pattern. With the fixed spray pattern, the water comes out in a steady stream. With the oscillating spray pattern, the water sprays out in small bursts.

Third, the Dusar showerao separations system is easier to clean than older showerheads. Because it separates the hot and cold water, it does not collect dirt on its internal components. As a result, it requires much less maintenance than other showerheads.

Fourth, the Dusar showerao separations system saves energy. When the user turns off only the cold water, the system uses less electricity. This is because the heater will stop heating the water immediately. Since the hot water is still running, however, the system continues to heat the water. Thus, the user can save money on his or her electric bill.

Fifth, the Dusar showerao separations system works with standard plumbing systems. Most people already own their home’s plumbing system. As a result, they are familiar with how it works. They know where the faucets are located and which pipes connect to which fixtures. Therefore, installing the Dusar showerao separations system is very simple.

Sixth, the [Dusar Duschaotrennungen](https://www.dusbad.de/) system meets all four of the DOE requirements. The Dusar showerao separations system replaces existing showerheads, it is easy to install, it is relatively inexpensive, and it is available within three years.
