post back here on what you decide to do, that is a very cool system.

you have hippies around your area? i know in strathacona here they have a one or a few 'test' houses where they're running geo thermal, sewage and water creation that basically has no impact on the environment.. if you got those, the students/hippies are going to tell you everything, rather than the sales telling you everything they want you to hear
