Take a look at this site for a Geothermal HVAC installation in a home of 1000 square feet ( www.duanesworld.net ). Follow the Geothermal HVAC links on the page or click on the title of this Blog Entry.

This site contains pictures of the complete installation process, listing of components, key learnings, and other notes. There is also a Blog called the Notebook ( www.duanesworld.net/notebook ) which contains further information and issues with the installation and operation of the Geothermal HVAC system.

There are data charts showing past energy usage as well as current energy usage. The Real Time Data page shows the current system in operation. This page tracks the amount of electricity used during the systems operation and also temperatures of the systems component freon, ground loops, water, and air.
