As part of the Southwest Border Regional Commission demonstration program on Solar Upgrading of Low-Income Housing, three different types of passive breadbox solar water heaters were designed. Using these designs, a total of six solar water heaters have been installed on public housing units in Las Cruces; these systems act as preheaters to the existing conventional gas-fired water heaters. Under a separate contract from the National Center for Appropriate Technology, four of these installations have been instrumented with two Btu meters each to measure the thermal output of both the solar preheater and conventional backup system. This has enabled measurement of the actual solar fraction of the four instrumented solar systems. The design and construction of the water heaters is described, and the actual performance of the systems is compared with the predicted performance.
