Has anyone used underground piping before to cool a house? Answered
I bought a 110 Victorian home in Middle Georgia and was studying about installing underground piping to help cool the house. Has anyone experimented with 5 inch PVC before underground to cool with? I took a study of temps in the house, attic and crawl-space to see if I pulled air from the crawl space, I could use that cool air to help circulate in the house to assist cooling. I found that the crawl-space was actually as close to the outside temp. It wouldn't help. I then studied using piping to put under ground about 3 feet and use a to-and-from push fans then tie it into the fan-only central heat and air system. I then wonderered if I would cause a positive preasure issue. I haven't tested it yet, but I think the ground temp is about 68 degrees constant if you go at least 3 feet deep! Any comments?
