Many buildings will be able to switch to one of the cleanest fuels using their existing equipment. Others may need to replace or upgrade components of their systems. Contact NYC Clean Heat to answer any questions.

1.   Know when you need to switch

Beginning July 1, 2012, buildings that currently use No. 6 oil will need to switch to a cleaner fuel before their three-year certificate of operation expires. To find out when your boiler permit expires click here and enter your building’s address. Planning well in advance of the expiration date will give you the most flexibility and options for your building. Learn more about regulations and the permitting process.

2.   Understand conversion options

Buildings that currently burn No. 6 and No. 4 heating oil have several conversion options to choose from when switching to cleaner fuels. These include Ultra-Low Sulfur 2 oil, biodiesel, natural gas, and steam.   

3.   Consider energy efficiency

Most buildings that utilize heavy oil and are required to switch to cleaner fuels must also comply with the City's energy efficiency laws, the Greener Greater Buildings Plan. At a minimum, pursuing energy efficiency and a fuel conversion at the same time will improve heating system performance, reduce fuel usage and costs.

4.   Obtain costs estimates

Start by contacting your existing fuel supplier or boiler service provider to ask how they can assist you with converting to a cleaner fuel and to obtain cost estimates. If more extensive work to your heating system is needed, you may also need to consult a licensed engineer. If you plan to seek bids from multiple contractors, make sure to submit the most detailed specifications possible and ask contractors to include pricing for all required items.

5.   Contact your utility if necessary

If you are interested in connecting to the natural gas system you will need to contact Con Edison or National Grid, depending on which utility serves your neighborhood, to determine if there will be costs for connecting to their gas distribution system. It is best to obtain cost estimates for your fuel conversion work prior to contacting your gas utility so that you are ready to take action. If you live in Manhattan below 96th street and are interested in converting to steam, contact Con Edison Steam.

6.   Evaluate Incentives and Financing Options

Converting to a cleaner fuel will likely include upfront costs. Learn more about financing and incentives.
