18x8 - This Old House

The show opens at Nantucket's Whaling Museum with curator Mike Jehle. At the site, we see the first of two wells being drilled for the Bentley's ground-source heat pump; they meet an expert in the technology, Carl Orio, who explains how the heat pump works off the ambient temperature in the groundwater. Then we take a tour of some of the island's best open spaces, preserved through the efforts of the Nantucket Land Bank, a public body that competes against developers on the open market using funds it receives from a 2% fee accessed on every real estate transaction on the island. Back at the site, homeowner Kathy McGrew Bentley is hard at work at decisions about her kitchen and floors - our master carpenter reviews wood floor options with her and general contractor Bruce Killen. Our host discusses decisions about the electrical and lighting plans with lighting designer Melissa Guenet and electrician Sally Kay Bates.
