About Steam Heating Systems

Steam heating systems use a boiler to burn heating oil or natural gas to produce steam on-site. A system of pipes and radiators then distributes this steam to provide heat throughout the building.

Many steam systems are decades old and haven’t been updated since they were originally built. As a result, they waste heat and cause other issues, such as units that are either too hot or too cold or banging or hissing pipes.

Make Upgrades to Save Energy and Money

You may think there’s nothing you can do but about these issues, but there are cost-effective solutions. The best approach is to address the system as a whole. You can:

  • Clean and tune the boiler to ensure your boiler is operating as efficiently as possible, or for older boilers in need of replacement, resize and replace the boiler.
  • Install vents on pipes to help draw steam to apartments furthest from the boiler.
  • Install modern heat controls, which use wireless sensors to help maintain comfortable apartment temperatures.
  • Install thermostatic radiator valves (and orifice plates for two-pipe steam systems) to give residents control over apartment temperatures and reduce overheating.

To get the most out of these upgrades, you can also:

  • Install pipe and boiler insulation to prevent the loss of heat before it reaches apartments.
  • Repair steam traps on radiators to ensure efficient release of steam.

Making these upgrades can reduce the fuel used for heating by 15 to 20 percent and help reduce overheating and clanging pipes.

Find a Contractor

The NYC Retrofit Accelerator has trained and qualified contractors to perform steam heating system upgrades. In many cases, these contractors can provide all of the services for a steam system upgrade. But in some cases engineering services should also be considered.

For Contractors

If you are interested in becoming a qualified contractor, you can respond to New York City’s Request for Qualifications for Providers of Steam System Retrofits here.

A classroom orientation is required for all respondents offering steam heating system upgrades. The classroom orientation is not required for those who have only applied to offer heat controls or energy management systems. Orientations will be scheduled on an as-needed basis. Check here to see if one has been scheduled, or contact
