Solar Shower at CCAT
The idea of a hot shower outside on a cool summer night is very appealing. CCAT developed just the thing for the occasion! Several versions of solar showers are available to build or purchase. Also, several reasons exist as to why one might chose this alternative form of energy for heating water for bathing purposes.
First, we will examine the question of why one might choose solar energy over other forms to heat water. Solar energy is accessible almost anywhere. It is easily used for heating up water in a shower system. The cost of a solar shower system verses a gas heated or electrically heated system is far less. Looking at the Energy Star website provided by the EPA, one observes that water heating is typically the third largest energy expense in your home (after space heating and cooling). Water heating typically accounts for about 14% of your utility bill. One way to reduce water-heating costs would be to replace your old water heater with an alternative form of water heating such as solar energy.
A solar water heater includes collectors{solar heating panels} mounted on the roof or in a clear area of the yard, a separate storage tank near the conventional heater in the home, connecting pipe, and a controller. Solar water heaters reduce the annual fuel cost of supplying hot water to your home by more than half. Throughout the year, the solar system preheats the water before it reache s the conventional water heater. During the summer, it may provide all the required heat.
Several versions of solar showers are illustrated in photos from websites cited at the end of this document. The first photo (figure1.1) is an esthetically pleasi ng pool and spa type shower for outdoor patio use. This solar model is stationary and can be used in the hot summer months for those days in the garden or out by the pool. It is said to work well and is totally sun reliant for energy. You may visit the web page listed for one site on which you can purchase the shower or gain more information on it. This type of shower goes for around $265. The second photo (figure 2.1) is of the more familiar camping types portable solar showers. Most models found through research show a gain from 60 degrees to 110 degrees Fahrenheit in about three hours when in the sun. These showers consist of various types of black or silver bags and tubing. They tend to run about $10 in price. Finally, we have the CCAT version of the solar shower (figure 3.1).
