Hardware Package and Workshop Development for Homeowner Solar Water Heater

摘要

The project objective was the development of a hardware package and a companion two day workshop necessary to assist homeowners with the fabrication and installation of a solar water heater at a cost of $300 to $400. It was the purpose of this project to (1) develop a standard solar hot water heater package, (2) develop a workshop for the assembly of these components by the homeowner, (3) provide guidance on how the components may be retrofit to existing homes in accordance with local codes and good practices, (4) provide operating and maintenance instructions, and (5) provide this community serivce at a target cost of $300 to $400 for the complete solar water package including the enrollment and 1-1/2 day workshop. The solar hot water system's thermal performance and development of a solar company are discussed. Nationwide expansion of the program is proposed. Included in an appendix is a more thorough discussion of solar water heating system and workshop. Also included is a study of the potential of the workshop and how the potential can be reached. The workshop is evaluated statistically. A new double walled heat exchanger is also discussed. (ERA citation 06:016700)
