The TEA solar air heating collectors described in this book are very well thought out designs. The TEA system uses solar air heating collectors that are integrated with the building's roof or wall to make a highly efficient, cost effective, and long lived solar heating system. The collectors are simple, relatively straight forward to build, and look great. These collectors were developed by TEA in the late 70's and were the culmination of an extensive design and testing program.
The authors of the book are Peter Temple and Jennifer Adams. I want to thank Peter for his permission to allow this material to be made available for download. Peter is currently teaching classes in Building Science and Super Energy-Efficient Building Design at Keene State College Architecture Department. Peter also works as an building energy consultant, including buildings with near net-zero energy use.
Some things to like about TEA collector design and the Construction manual:
It provides well thought out designs for
large roof and wall integrated collectors.
The collector designs are straight
forward, and use commonly available materials and tools. Ordinary
house building skills, tools are all that is required to build these
Extensive testing was done to
validate the collector design and materials used.
The roof/wall integrated design
reduces material use, and reduces collector cost and labor.
The design can be
tailored to an individual home's roof or wall size and shape.
The manual includes details on
a full solar air heating systems, including: collector, storage, ducting
system, and control system. Designs for both new construction and
retrofit are covered.
The collector provides good
performance, which was validated by actual testing.
The manual includes information on how to size the system, how to construct the system, and a full set of detailed construction drawings.
The book describes a full solar home heating system that includes a large collector, a heat storage system, and a ducting and control system to connect all this together -- this will be a big project for anyone. But, as the book points out, a more modest sized collector can be used without a heat storage system, and with a much simpler control and duct system. This smaller system could be a very manageable project for either new construction or retrofit, and could still put a sizable dent in your heating bill. In a passive solar house design, adding such a small system could improve the solar fraction significantly.
For people with existing homes that have available south facing wall space, retrofitting the wall collector could be very attractive. The TEA collectors use vertical supply and return manifolds located on the left and right ends of the collector, which seem more suited to retrofit situations than the usual collector designs with vents or manifolds along the top and bottom.
In spite of the 30 years that have passed since these collectors were designed, there is little in the design that is out of date. But, here is a list of changes that one might consider based on materials and design practices that have changed some over the years since these collectors were developed ...
