Geothermal heating & cooling - Calgary

[michika]

Is anyone in the Calgary area doing this, or thinking of doing this? (http://www.canren.gc.ca/prod_serv/in...d=150&PgId=769 ) I'm considering it for our new house, and wanted some first hand opinions or information about experiences.

I'm looking at it for a few reasons, 1) I want to put in a very large tank into my house, 2) I hear it can reduce the cost of your utilities, 3) eco-friendly is always nice.

I suppose I want to know if it really is cost-efficient, or if the time to recoup your initial investment is really far off. I also want to know how people have faired with it in Calgary and its surrounding areas.
