Solar equipment is offered by the city for the heating of swimming pools, process water, and domestic hot water. The pieces of hardware (solar collectors, controls and storage tanks) are owned and maintained by the city under a rental agreement. The renter pays an initial installation fee and a monthly utility fee. These amounts vary according to the size of the installation.

In planning for a solar heating installation it is important to provide sufficient exposure on a south or southwest facing roof area. Other factors to consider include the distance and access to the conventional heating equipment, space constraints for the solar accessories and shading of the solar collectors (either daily or seasonally).

For any questions concerning the Solar Utility Program, or for assistance in planning for a solar heating installation, call 984-3183 - Santa Clara City Solar Utility.

TYPICAL SOLAR HEATING SYSTEMS AVAILABLE

SWIMMING POOLS

The swimming pool solar heating system would normally connect into the standard pool circulating system and operate in conjunction with a conventional heater. The system that the city installs would include the collectors, the plumbing between collectors and the pump/filter equipment, and a thermostatic control to regulate the flow to the collectors.

DOMESTIC HOT WATER

A solar domestic water heating system would include two to three collectors, a
storage tank, circulating pump and an automatic control. Since solar cannot pro-
vide 100% of the heating, some conventional backup heater would be required.
This could be installed as a separate hot water heater plumbed in series with the
solar storage tank, or the solar system may be installed with an electric heating
element integral with the solar storage tank.

PROCESS WATER HEATING

Solar process water heating could be useful for any of a number of industrial or
commercial grocesses. Typically, the water could be preheated to approximately
100° to 160° F. Some conventional heating system would usually be required as
a backup.

Energy Research and Development Administration

Division of Solar Energy

The Solar Energy Research, Development and Demonstration Act of October, 1974 authorized a Federal effort to establish solar energy as a viable energy resource for the United States. Under the provisions of the 1974 Energy Reorganization Act, ERDA has the central responsibility for the Federal Government's solar energy program.

ERDA is conducting a National Program for Solar Heating and Cooling of Buildings, with the assistance of the Department of Housing and Urban Development (HUD) and other Federal agencies.

The primary goal of the program is to work with industry in the development and ear introduction of economically competitive and environmentally acceptable solar energy systems to help meet national energy requirements and reduce dependence on fossil fuel supplies. The thrust of the program is to demonstrate the economic viability of solar energy for the heating and cooling of buildings within the five-year period of the Federally-sponsored program.

One of the basic program elements is the demonstration of solar heating and cooling in commercial buildings under various climatic conditions. The first stage of the demonstrations provided for the installation and operation of state-of-the-art technology. As solar energy technology improves, advances will be incorporated in the demonstration projects.

In addition to ERDA's solar energy pr gram, many projects are underway in other Federal agencies, industry, universities, small businesses, and state and local governments. Together these activities comprise the national solar energy effort.
