We’re having a geothermal HVAC system installed and they started drilling the wells a couple weeks ago. The original plan was to have four 250-foot holes for the larger geothermal unit and three 250-foot holes for the smaller unit (because of the length of the house, it’s more efficient and cost effective to have two units like that). However, around 80 feet down, the driller hit a big area of sand and the hole kept collapsing back on itself almost immediately, so the hole plan had to change. There will be twelve 80-foot holes for the larger unit and eight 90-foot holes for the smaller unit. Our whole back yard is currently dotted with holes spouting black tubing!
Once it’s all done, everything will be hidden four feet underground, so it’s no big deal. It will actually be a little easier on the geothermal pump because of the shallower wells. We just have to make sure that any future construction plans don’t dig down deeper than four feet!
No in-ground pool for us!
