Would the PVC ducts in the floor need to be insulated? Would the slab then need to be insulated? I like the idea just don't want to add tons of cost. Is doing a well pump going to off out the geothermal savings? I just am having a hard time seeing a pump run for that long without drawing a lot of power. The discharge/pond idea is great though. I can solar power mine as well, and one day plan to, but that is a huge extra cost. Thanks for all your advice its going to help me make the best choice.
