Feldman, Jr, K T

A one year research and development project was conducted with NMERDI and Energy Engineering, Inc. (EEI) support to improve the design, manufacturing, testing, certification, shipping and installation of the heatpipe (tm) Passive Solar Water Heater. The objectives of the project were to develop a more cost-effective heatpipe (tm) system and the machines and manufacturing processes needed to produce it in the EEI Albuquerque plan. The project included redesign of the collector frames and mounting hardware to use aluminum extrusions, redesign of the tank cover to use molded fiberglass, new polisocynaurate foam insulation for the tank covers, a new heat pipe extrusion and welding process, new shipping and crating techniques, and new system data. The test data indicates that the heatpipe (tm) system efficiency is equal to the best active systems and is significantly better than most passive solar DHW systems.
