This Old House

Essex 2012/13 Part 4: Water Feature and Geothermal, Demolition (34x19)

:

Roger meets aquatic systems specialist Yorgos Gregory to learn about our existing and neglected water feature and to see what it takes to restore it to good condition and function. Kevin meets Richard to learn the anatomy of a water well and how we can revive ours. Drilling expert Roger Skillings arrives with a drilling rig to diagnose and treat the problem. In the backyard, Kevin finds master electrician Allen Gallant working on a 100-yard trench from the house to the street down below. Excavation revealed that the service was once buried, but then put above ground again in the 1960s. Today he's reburying it 18 inches down with PVC conduit that follows the contour of the land thanks to a PVC heater. At the end of the day, Kevin finds the drilling rig still on site as renewable energy specialist Ross Trethewey explains why this is an ideal site for geothermal heating and cooling and how it will work.
