Wormley Row

Located on Prospect Street in the heart of Georgetown, the Wormley School was founded in 1885 and named for James Wormley, one of Washington, D.C.’s first prominent African-American businessmen. It was segregated until 1952, and operated by the D.C. Public Schools until 1994. In 2009, the structure was transformed into seven luxurious, million-dollar condominiums.

“Our charge from the builder was to deliver a best-of-the-best heating and cooling system to meet its vision for the project,” explains Dan Foley, president, Foley Mechanical, Inc., of Lorton, Va. “With ceiling heights of nine to 14 feet and 6-foot to 8-foot-high windows, ‘best of the best’ meant a radiant floor heating system.”

The Uponor radiant floor heating system in the structure features more than 15,000 feet of PEX tubing. To facilitate tubing installation in just two days, Foley Mechanical adapted new tools that wrap PEX pipe, tie it off and cut in half a second.

“The tools cost a lot, but my labor costs more,” says Foley. “These devices saved money for our clients in the form of reduced installation time. More importantly, they also saved wear and tear on my crews.”

Radiant and Snow Melt for Comfort, Convenience

While radiant heat provides interior comfort and efficiency, an Uponor snow melt system provides safe travel on the outside parking ramp and public walkways.

“We used about 3,000 feet of PEX tubing to create a snow melt system which will eliminate the need to shovel snow or salt walkways during the winter months,” says Foley. “It’s the ultimate system for safety and convenience.”
