When the 1717 East 18th Street co-op board first began exploring ways to increase resident comfort and improve the efficiency of their building’s one-pipe steam heating system, installing a new heating control system was at the top of their list. After meeting with a heating contractor, however, the board learned that although new controls could help to reduce boiler run-times, saving fuel and money, a more holistic approach was needed to really improve steam heating system performance.

Facts about the building

Project type: One-Pipe Steam Heating System Upgrade

Location: Brooklyn, NY

Year of project completion: 2015

Base building completed: 1957

Existing Conditions

Built in 1957, 1717 East 18th Street faced many of the challenges typical in older steam-heated buildings, including: uneven heating with hot and cold spots; overheating with residents opening windows in winter and consequent heating fuel waste; loud, clanging pipes; and occasional radiator leaks.

  • NYC Accelerator


  • Balanced flow of steam with more consistent and even heating to all apartments.
  • Greater ability to regulate boiler cycles and control building temperature.
  • More efficient boiler and burner operation, with energy and fuel cost savings.
  • Higher quality steam, quieter radiators, reduced leaking, and longer equipment lifespans.
  • Increased occupant comfort and satisfaction.

Lessons Learned

The upgrades completed at 18th Street were relatively straightforward, from a technical perspective. Getting building staff and residents to buy into the proposed scope of work, and later adjusting to changes in apartment temperatures, proved to be a greater challenge. Ongoing communication with residents and staff about the reasons for, and benefits of, the upgrades was essential to getting their support and consent.

We were eager to install new boiler controls to balance heat across the building and reduce energy waste. In the process, we learned more about our system, addressed underlying issues, developed a more energy-conscious community of residents, and saved money.Dr. Samuel Thomas, President, 1717 E 18th St. Owners Corp.
