I've heard of the system before, but just recently one of my Team Lead's clients took on the project. Its a heat source that pumps heat from the Earth. This system is very expensive running between $40k -$80k. They say that the savings in the long run are well worth it and the system is super energy efficient. Geothermal systems can be connected to HVAC and radiant floor heating which I heard was the most comfortable form of heat in a house. The state will provide a 30% tax write off on the system and for anything involved to make the system work for your home.

I just wanted to get other people's opinion on this system or gain some more knowledge about it.

So what do you guys think?
