If you have a sustainable watertable, look into the open loop system. My opinion is that there are more advantages than disadvantages compared to closed loop. This starts with a fraction of the install labor & material costs.
Another consideration might be an air-to-air heat pump for less labor and costs. I have a carrier heat pump for my 3 car garage and bonus room above. Can't tell you how good it is or isn't. I have only started the system a couple of times since it was installed 15 months ago.
