I can't see why anyone WOULDN"T want to isntall a geothermal system. Consider this: We live in a Canadian city called Winnipeg (http://en.wikipedia.org/wiki/Winnipeg) about 8 hours NW of Minneapolis. Most of our fellow Canucks call this place Winterpeg 'cause it's so freakin cold here in the winter. Our kids haven't been allowed outside at recess for the last month because it's been so cold. It's warmer at the North Pole. You get the idea. We put a geothermal system on our new house 2 years ago and it's been great. It keeps us at a toasty 23degrees C even if the outside temp is 40 degrees below zero Celsius ( same as -40 F) We have a 2-well system supplying a 5tonne heat pump. The house is well insulated from basement to attic which is key. It is incredibly cheap to run. There is a backup electric heater built in to the system, but it has only kicked in ONCE. In addition, it also pre-heats all of our hot water as a by-product. It really is the best thing going for heating and cooling your house, shop, office building etc...
