Natural Gas Conversions

Professional Help For Your Gas Conversion.

-Locate Professional Help from an energy consultant like myself. 800-524-4280, I wrote this article, Jay Sullivan.  My job as an energy consultant is to help you with every step of the process from engineering, heat loss calculations, equipment selection, to getting equipment & labor quotes as well as help you negotiate prices with contractors. The more knowledgeable you are about the process the better deals you get from every contractor involved with the project.  Let me be your eyes & ears /your knowledgeable assistant on the project for a first visit fee + $ an hourly rate.  (fee & hours needed determined by the scope of project.)

-Discussing your energy reduction goals, and the best possibilities for your building.

1) The Meeting- visit 1- We meet and discuss your goals for the building, and walk around the basement so I can check the current heating system and see what kind of piping is within the walls of the building. If you want to keep the plan simple (straight gas conversion to your current equipment) we can gather the information needed for the Gas Load Letter on the first visit.

-More advanced gas conversion plans.

2) If you want to explore the options of going with a “High Efficiency” option, with brand new Modulating & Condensing boilers, multi linked together for Ultra High efficiency ratings over 90%, I am more than happy to help you explore those options with you.  However, this will take many more calculations.  The first set of calculations we need is called a  Heat Loss.
Our NYSERDA certified engineers are experienced with commercial & high density buildings.  They perform a heat loss, which is a series of calculations that determine how many BTU’s of heat the building truly requires based on the buildings true heating requirements, counting for the amount of heating the building naturally loses through the windows, walls, ceiling etc.  Remember all old boilers were over sized, and the new replacement will likely be (should be) a good deal smaller. You may have upgraded the windows, the roof, and made other improvements since the building was originally built and everything affects the about of BTU’s needed to heat the building.

A professional heat loss ensures you save as much money as
possible by sizing the equipment perfectly. Do not cut corners by skipping a heat loss, it will cost you tens- to hundreds of thousands of dollars in over sized equipment and a life time of fuel wasted.  Your average plumber or heating supply store is going to suggest  you go back with the same exact size boiler you currently have, which is completely insane/ should be illegal.  Not to mention the city will not even approve heating upgrades without the proper engineering and drawn out plans submitted to the DOB, after approval from ConEd.

The Second set of calculations or engineering we need is called Energy Modeling. Our NYSERDA certified engineers need to preform the energy modeling survey for your commercial & high density buildings.  Energy Modeling shows, unquestionably, exact, the exact amount of money your spend on your heating bills, and what you can save with all the different heating upgrades you building qualified for.   If you want to tap into the tax credits, rebates, state & local energy incentives you want a professional energy modeling survey.

-Once we know what type of equipment will be used for your gas conversion, and how many BTU’s it will require. We can send in the request letter.

Acknowledgment letter from ConEd. A few weeks after we submit the gas load letter ConEd will let us know if we have enough gas available for the gas conversion/ heating upgrade or not.  Hopefully there is enough gas and ConEd assigns us and the building a representative.  This rep is very important to the process and we will be talking to this person many times throughout the job process.

-Going with brand new equipment?   We need quotes.

3) Equipment selection. There are almost an unlimited amount of options for new heating systems and there is a mountain of information to go through online.  Rather than overwhelming you with information, we talk about your goals.  I’ll create a short list of all the conventional or high efficiency options that are appropriate for you building and the goals you want to achieve.   We discuss the benefits and draw backs and rough prices for each direction and each manufacture.

-Now that we have a real plan and know what type of system and equipment we want to use, I can get your all the labor quotes.

4) Contractor walk through. It’s time to get the tradesmen in the building.  Plumbers, pipe fitters, boiler builders, electricians, low voltage wiring, the chimney liner, oil tank cleaners, we need a ton of estimates in order to make sure we get the right prices on every aspect of the job.  The contracting companies chosen depends on the size and requirements of the jobs.  Bids are open to all qualified contractors but the high efficiency heating options (anything over 90+% efficient) we recommend specific qualified contractors we know and have worked with in the past, otherwise we are just asking for problems.  High efficiency wall hung boilers have specific installations requirements and inspectors are known to be very difficult to work with, when when they are installed 100% perfectly. 

Note: High efficiency heating equipment has very specific installation requirements and the contractors we work on a regular basis have all have proven themselves. For large heating applications requiring a duel fuel heating system. We work with 2 of the biggest on site boiler manufactures in the greater NYC area.  We also have a number of mechanical companies for conventional heating job in between.

Now that we sent and had our gas load request approved. 
I got quotes for the equipment and labor quotes from all the installers.

5) Quotes submission.  After equipment selection I send an email to all the bidding contractors, let them know the equipment we selected and tell them to submit quotes for the labor portion of the job, and my office begins fills with quotes.  As this point I have called plumbing suppliers and got quotes for the rough materials necessary for the job.  Material quotes are quick to get, as fast as 48 hours.  Getting quotes from contractor takes some time, they all have to review the construction documents and tour the building, as well as make detailed material lists and figure out how many hours the job will take, permits etc.

5) Quote Presentation. At this point I have multiple quotes for every aspect of the oil to gas conversion and I present you with all the quotes and information you need to make an educated decision on if or not you are going to proceed with the project.   Now that you have a few different options to your gas conversion and heating system upgrade and all the quotes for the options you choose we can begin on the project.

-Now that you have the good, or bad news from ConEd.
I have helped you get multiple quotes for equipment and all the contractors needed for the work it’s time to start the project.

7, 8, 10->  Now that we have the plan it’s time to begin!   We need an architect to draw up blueprints, temporary heating system, DOT permits, EPA signatures, expediting services and choosing an escrow account..  Often times there is well over hundred hours of research and set up time needed that goes into an oil-to-gas conversion for commercial buildings in NY before one nut or bolt is turned, and historic or landmark Manhattan buildings can take even longer.

*Engineering Notice*

One very important thing not mentioned is engineering.  Engineering is a little tricky to talk about for an oil to gas conversion because different engineers are needed for different heating upgrade plans.  The size of building, type of upgrade and amount of “full engineering” required will dictate what type of engineers we need to use.  Just a “straight conversion”, converting a field fabricated boilers to gas or duel fuel requires light engineering.  A gas conversion including high-efficiency options or other major changes to the existing heating system requires medium to full engineering services.  More about engineering requirements here.


Who to call for an oil to gas conversion quote for a commercial building in the greater NYC area? Give me a call.
I started putting this website together in 2009 and have helped many NYC buildings owners convert to gas since.  I have all the skills, contractors, supply stores etc,  needed for every step of the process.
I look forward to working with you on your NYC gas conversion soon.

If you have no clue about heating systems, possibly upgrades, the complex issues with NYC heating improvements etc.  You should start with my educational service first.   Thank you-
