New York City, and in particular Manhattan, saw two steam systems built in 1882.  The New York Steam Company was well-engineered, began operating in March, and continues to operate today with a much enlarged distribution network.  The American Heating and Power Company began service later that year and managed to cause several explosions in lower Manhattan that were apparently caused by water hammer.  The become suspended operations shortly thereafter and was bankrupt.

A third system, the Prall New York Heating Company, was based on William E. Prall's Superheated water design.  Apart from cooking a delicious meal for the Annual Meeting of the American Society of Civil Engineers in November 1880, the company did not have the financial resources to build a system.  Prall later designed the Boston Heating Company that began operating in 1888 and became a spectacular failure. 

The New York Steam Company encountered financial difficulties during the First World War, as did many district heating systems.  They entered receivership in April 1918 and emerged in 1921 as the New York Steam Corporation.  The Consolidated Gas Company bought a controlling interest in the steam company in 1929 and it was fuly merged into Con Ed in 1954.

Any block of buildings might be heated as easily as are the great inns and other large buildings, if the several owners would only join hands; but if they will not there is place and profit for a steam heating company in New-York. A company organized as the gas companies are, with boiler houses and steam mains properly jacketed, could furnish heat to houses at a much smaller cost than any householder can make it for himself, and such a company would not long lack business. The insurance associations would lend it powerful aid by their influence, and every physician would become a personal advocate of its cause.

It has been somewhat more than a year since the Evening Post first suggested the propriety of heating towns and cities by steam, the steam to be furnished to householders by a company, precisely as gas is already furnished. When we made this suggestion and pointed out the desirability of its adoption we had little doubt that in due time some company would act upon it, but we had little reason to expect that practical measures would follow as speedily as they have done.

[1878] The Prall System of Heating Cities and Supplying Power by Hot Water, by William E. Prall
It is true that the more modern and expensive establishments, such as hotels, public buildings, and a few of the more costly private houses, have been provided with steam-heating apparatus, but while it may justify the expenditure for separate steam generators, and maintenance thereof, in such places, it would not be within the means of the masses to do so, hence many attempts have lately' been made to make steam wholesale as it were, and retail it to customers both for heating, and power purposes, through pipes, extending over a large area, and at considerable distances from the generators or boilers.
Confined to comparatively small areas the system has proved profitable, as shown by the Manhattan Real Estate Association, who for many years past have supplied the district lying between Thomas and Worth streets on Broadway, New York, with both heat and power, from a battery of boilers. The system has met with equal success in other cities for many years, notwithstanding the immense loss from radiation and condensation.

1881 "The Fuel of the Future," The New York Times, June 21, 1881, Page 4.
There an be no reasonable doubt that the fuel of the future, for use in our dwelling-houses, will be some kind of gas, distributed through the City precisely as illuminating gas is now delivered. The use of coal is extravagant, wasteful, and inconvenient, and the dust and smoke arising from it add much to the impurities of the air, while the removal of from 100 to 200 pounds of ashes for every ton of coal burned is a great annoyance. Several substitutes for solid fuel have been proposed, all of which have strong advocates. These are steam heat, hot water, and gaseous fuel. So far as the warming of dwellings is concerned, it must be admitted that Mr. Holly has succeeded in demonstrating that steam can be generated at a central station and economically distributed for this purpose. But for cooking purposes steam beat supplied in this way cannot be made available. At the present time it is the custom to use steam for heating purposes at higher pressures than formerly, sometimes as high as twenty pounds to the square inch. The prospects for the hot water system do not seem promising of great success. The practical difficulty of maintaining constant circulation through a great number of pipes running in every direction seems to be almost insurmountable.
Moreover, granting that this difficulty is overcome in practice, a fatal objection still remains, which is that the temperature of an apartment heated by hot-water pipes cannot be easily regulated; for, if the room is too warm, the water cannot be shut off like steam, but must remain in the pipes if the circulation is interrupted, and part with its beat gradually, or if more beat is required, the fires must be quickened, and the water has to make an entire circuit before the benefit is felt. The temperature of the water in the Prall system, which is, perhaps, the best known of all, is to be about 400° to 425° Fahrenheit. Such a high temperature involves a pressure at the boiler of not less than nineteen or twenty atmospheres, and it is doubtful if such a pressure can be regarded as quite safe. The system of heating that is destined to supersede all others is by means of a gaseous fuel. For this purpose a suitable gas can be manufactured very cheaply, and there need be no more difficulty or danger attending its use than is met with now in the use of illuminating gas.
By passing. current of steam through an incandescent mass of coal in a suitable furnace, the oxygen of the steam combines with the carbon of the coal to form combustible gas, while the other constituent of the steam, hydrogen gas, which is also combustible, is set free. The mixture of carbon oxide and hydrogen thus produced is the so-called " water gas," and it is this gas which seems likely to come largely into use for a household fuel. A not unimportant fact in connection with this gas is that although it will explode when mixed with the proper proportion of air, its explosive energy is much less than that of ordinary illuminating gas. The introduction of gaseous fuel would not necessitate very great changes in the stoves and ranges now in use.
The convenience and economy of the system commend it to every one

Plans were submitted to the Bureau of Buildings yesterday, by the Steam-heating and Power Company of this City, for a boiler-house, to be situated at Nos. 170, 172, and 174 Greenwich-street. The building is to be of brick, with a frontage of 77 feet, a depth of 120 feet, and five stories high. The plans are drawn by Charles E. Emery, engineer, and the building will be erected by the company under the direction of Mr. Emery and Mr. Crittenden, the Superintendent. The estimated cost of the building is $175,000.

The New York Steam Company turned on its power in nearly a mile of pipes on Tuesday night. These pipes are under Greenwich street from Cortlandt street to Warren street, and in Warren, Barclay, and Courtlandt streets, Workmen are laying others in deep trenches in Broadway above and below Liberty street. There have been some complaints by merchants of the slowness with which the work progresses, but it is said that this is due to the fact that the pipes are surrounded by brickwork tiled in with mineral wool and covered with wood or stone.  The Broadway and Cortlandt street mains are 15-inch pipes; the ethers 11-inch pipes. It is designed to lay pipes along Broadway from the Battery to Canal street. The power station to supply this district is now building on the site of the Pacific Hotel on Greenwich street, above Cortlandt street. The third story is now being finished. It is to be six stories in height. and taller and proportionately heavier than the Post Office. It will have two chimneys each 225 feet high, or higher than the Bunker Hill monument. It will contain sixty-four boilers of 250 horse power each. The company at present intends to equip nine other such
stations in Varies parts of the city. Although the steam was turned on, it as mot yet been furnished to any customers.

Announces, to avoid misapprehension, that is has been supplying steam for eight months, and that it is now prepared to furnish steam in any quantity on the line of its mains, at an average pressure of 75 pounds, day and night.
The accidents to steam-pipes, so often chronicled in the daily papers, and the consequent opening and reopening of public streets on the east side of Broadway and the escape of steam from man-holes has nothing to do with the work of this company, as such troubles began many months after this Company began operations, and nearly all of its pipes are west of Broadway.
This Company lays its pipes in clean boards, in a substantial conduit, usually of brick. It does not use lampblack or tan bark for packing purposes.
This company has pipes in Broadway, extending from Bowling Green to Warren Street, generally on the west side of the center of the street. It also has pipes in Wall Street, in Pine, Fulton, Maiden Lane, Ann Street, Theater Alley, and Park Row. In no case does escaping from manholes in the streets come from the pipes of this company.
On the West Side this company has pipes in Greenwich, Liberty, Cortlandt. Fulton, Vesey, Barclay, Park Place, and Warren Streets.
PROMINENT CONSUMERS ARE THE AMERICAN EXPRESS Co., Mutual Union Telegraph Co.. Chatham National Bank, and thirteen others on Broadway; Bank of New York; Alexander Duncan; the Stone Building on Liberty Street; Parke, Davis & Co., Maiden Lane; New York Commercial Advertiser, U.S. Illuminating Co.: Stockwell & Co., in Ann Street: Nash & Crook; S.V.

Stewart, Well Brothers: Smith & McNeil's restaurant, North River Bank; Metropolitan Job Printing Establishment, and eight others in Vesey Street: and C. H. Delamater & Co. and fourteen others in Cortlandt Street.
THE STEAM NOW FURNISHED BY THIS COMPANY IS generated at its station "B," in Greenwich Street, near Cortlandt, distinguished by its large chimney.
THE OFFICERS OF THE COMPANY ARE W.C. ANDREWS, President; William P. Shinn. Vice-President; J.A. Bostwick, Treasurer: R.E. Rockwell, Secretary; Charles E. Emery, Engineer and Superintendent.

Page 194:  The return pipes of the New York Steam Company finally caused so much difficulty from leakage, that the present management decided to dispense with them, and this has been done on the east side of Broadway and in many streets on the west side, by arranging that the water of condensation from the heating coils of the buildings be discharged to the sewers. This is the method originally adopted by the original Holly company, which, it is well known, has put up a large number of plants for heating buildings in small cities throughout the country. Its general plan in heating a dwelling, was to run the pipes to and from the radiators as usual, and discharge the water of condensation.

Confusion caused by city employees interfering with the New York Steam Company's water supply.
The light, heat and power supplied by the New-York Steam Company whose plant is at Washington and Dey sts., were shut off a little after 2.30 o'clock yesterday afternoon. Electric lights went out, elevators refused to run and heat was wanting.
The cause of all this confusion and inconvenience and discomfort was the shutting off of the water supply to the New York Steam Company. Employees of the Water Supply Department of the city were putting in a hydrant in front of the building without informing the steam company.  The hydrant was put in, but the but the employees forgot to turn on the water again.
The first thing the New York Steam Company's employees knew was that the water in their boilers was running low. The fires were put out. and an investigation was made. Steam was turned off in all the district which is supplied. Then it was learned that the water had been shut off. The Water Supply Department was informed and employees were hurriedly sent around to turn on the water again. But the lower part of the city for more than two hours was without light, heat and power so far as the big buildings were concerned.
Nearly all of the big buildings as far north as Duane-st., with West Broadway on the west and Nassau-st. on the east, extending to the Battery, get steam from this company. This steam used for running the dynamos and the elevators.
The shut-off of these three important factors in some of the big downtown buildings came unexpectedly and without warning. In the Stock-Exchange and other big buildings down town, which swarm with people, there was the utmost confusion. Most of the large halls and vestibules of the big sky-scraping buildings, which are usually lighted by electricity, were in Cimmerian darkness, and candle and lamps were used light up the halls.
The smaller buildings, which derive their entire lighting and heating power supply from the New-York Steam Company, were in a bad fix. Stout men perspired as they tolled up and down the tortuous stairways.
B. F. Seadler, secretary of the New-York Steam Company, said that no notice was given to the company. He said that some foreman took on himself the shutting off of the water and neglected to turn it on again. He further stated that it was no fault of the steam company. They were obliged to turn off the steam and bank the fires when the water ran low In the boilers.

1932 Fifty years of New York steam service; the story of the founding and development of a public utility, by New York Steam Corporation/

1932 Handbook of the National District Heating Association
Pages 9-12:  New York City.  The New York Steam Corporation supplies steam to consumers on Manhattan Island for heat and power. At the present time the corporation serves two districts-the downtown district and the uptown district-indicated on the maps.
The downtown district includes the area of large buildings constituting the financial and business center of lower Manhattan. The uptown district includes the rapidly developing business center, as well as the adjacent area of large apartment structures.
The corporation serves a total of 2460 consumers, occupying 1,824,236,000 cu. ft. of building space. To serve these consumers, during the year 1930, 10,189,919,000 lb. of steam were delivered to them from five boiler plants through 330,402 ft. of pipe, ranging in diameter from 2 in. to 24 in. The five boiler plants have an aggregate generating capacity of 7,170,000 lb. of steam per hr.
Consumers are served with steam at pressures ranging from 100 lb. to 150 lb. per sq. in. In the downtown district, a considerable portion of the steam is used for the generation of power, while in the uptown district the proportion of power service is much less. The sale of steam for power increases the summer load, but as existing isolated power plants using this service are discontinued from time to time, the amount of steam thus used is decreasing. Summer loads are improved to a small extent by the sale of steam to construction operations, which, in New York, are in progress to a great extent continuously.
The tremendous concentration of business, forces the use of high pressure and large pipes to supply the demand for steam service. The sub-surface space is so crowded with water, sewer, gas, and electric services that the generation of district-heating supply in any one location is limited by the inability to distribute steam from one point in excess of 4,000,000 lb. per hr.
Recent acquisitions to the list of customers are the Empire State Building and the federal government buildings on Manhattan Island.
Growth of the service has required during each of the past several years the installation of about three miles of pipe and an increase in station capacity of 300,000 to 600,000 lb. of steam per hr. A total generating capacity of 6200 kw. of electricity is installed in the five stations, all of the current generated being used to supply boiler plant auxiliaries. Coal is brought to the stations by barges on the East River and is hoisted directly to the bunkers except for the downtown station, to which the coal is hauled by trucks.
The greater part of the ashes are sold at the stations for construction purposes.
The New York Steam Corporation is the largest district-heating organization in the world and a statement of its earnings, expenses, and charges for the year ending December 31, 1930, is included to indicate how large such a heating service may become in a fertile field.
