When & Where would I need a Natural Gas Booster?

    Eh? What is the problem you are trying to solve? Your gas connection to the main and the associated meter — neither of which are yours to play with (you have to get the gas company involved) control the number of therms you can have.

    There was just a video on Facebook of a booster in NYC where it increased 4" to something higher for boilers.

    Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

    I have installed boosters they are $$$$$$.

    We had a Supermarket in West Hartford; CT. had a 6" gas main coming in . In the winter the gas utility would only guarantee 4" of gas pressure. They wanted to install a Munters Cargo Caire gas fired dehumidification system on the roof that required 12" of gas pressure. We had to rework a lot of gas pipe and install a booster for the whole system. Don't remember the total gas load but the booster cost 25k installed was 85K and that was probably 14 years ago.

    Its just a gas pump to raise the pressure. Usually in the older section of cities with old leaky underground gas lines where they can't raise the pressure do to leaks.

    It takes a bit of engineering from the gas utility and most locations will want a PE to design this system. The gas utility has to sign off that they can supply the load. And the local inspector will have to approve it.

    what happens when you start sucking in air through the main…

    Has to be engineered. Pressure in the main so air will not leak in if any leaks. They run low pressure in old cities downtown so the old pipe won't leak to much gas out. In NYC about 8 years ago an apartment building blew up. The existing gas pipe in the street was from 1887. Boston has/had wooden gas pipe in the streets.

    All that stuff should be replaced but…………………..its still out there. If it wasn't they wouldn't need to sell boosters

    or suck in water, that would be even better… my neighborhood only has 2psig in the street. and you can smell it all over the place.

    i think the idea of electrification is to only have to replace one 120 year old infrastructure.

    in my neighborhood it is only from about 1950. the stuff in old inner cities used to be town gas and was converted to methane as the natural gas distribution network was built out.
