The Westech Evacuated Tube Solar Collector is a device that absorbs thermal energy from the sun and converts it into usable heat. The heat is normally absorbed by water, or a freeze resistant water mix, which can then be used to supplement hot water heating...

The Drake Landing Solar Community is a 52-home subdivision that uses the sun's energy to supply 90% of space heating and up to 70% of domestic hot water needs. The system uses 800 commercial solar collectors in conjunction with seasonal storage to...
-
EnerWorks Rob Singlehurst describes their commercial Solar Water Heating systems and some recent case studies where these systems have been implemented. EnerWorks designs and manufactures solar heating equipment and solar collectors for commercial, industrial...
