The Mendota

Built in 1901, The Mendota is Washington DC’s oldest luxury apartment building. This historic building has been painstakingly restored over the years to preserve its unique architectural details. The Mendota’s original heating system consisted of a coal-fired boiler, which was later replaced with a steam boiler on a one-pipe steam system connected to column-style cast-iron radiators. After 40 years of operation, the boiler became inefficient and unreliable. Among other improvements, Foley Mechanical installed a Weil-McLain LGB-20 atmospheric draft steam boiler which improved resident comfort and offered major energy savings.
