Chronological List of District Heating
Systems in the United States |
The Springfield Electric Company installed an exhaust steam heating system in the fall of 1890.
The People's Hot Water Heating & Electric Co. installed a hot water district heating system in 1902. The two systems came under common ownership in 1903.
The hot water system was discontinued in 1956 and steam heating in 1968.

Another illustration of this use of exhaust steam can be quoted from the
Springfield Electric Company, and I am glad to see the president of that
company here. This pipe was laid last fall. The President informed me last
week that it worked perfectly. They deliver the steam through nearly 2,000
feet of mains at two and three pounds back pressure. They are so pleased
with this saving of exhaust steam that they propose an extension of the
mains the coming season.
Since reaching the city I have had the pleasure of asking Mr. Ide, of
Springfield, the amount of their heat. He does their heating now upon
nearly 1,000,000 cubic feet of space, and using but little to exceed
one-half of 100 horse power boiler; so that would fully sustain me in
these figures.
MR. IDE: My experience in heating has not been very long or extensive.
Last fall we put in about 2,000 feet of main, about one-third eight inch,
the balance six inch. Our station is favorably located in the central
business portion, and we conceived the idea of selling our exhaust steam.
We have a five year contract for furnishing power for an electric railway.
At present they are running 10 cars. We also run a motor circuit that is
now using about 50 horse power. We made contract with seven store
buildings to heat them for five years with exhaust steam at a price
averaging about $200 a year. The buildings contain about 100,000 cubic
feet of space each. We did not contract for any more at that time, because
we wanted to be sure to have sufficient exhaust steam to supply them. We
have now given about four months' service, which have been very
satisfactory in every respect, warming the buildings satisfactorily in the
coldest weather. We have never exceeded four pounds back pressure.
Ordinarily we carry two ounds back pressure, and the gauge shows a
reduction of about one pound at the extreme end of the mains. We estimate
that the expense of furnishing this exhaust steam is trifling. We do not
notice any difference in the consumption of coal required, and we now find
that with the surface exhaust steam we do not utilize over half. Next
summer we expect to add about a thousand feet more main. We think our
present steam will be sufficient to double our capacity. We estimate that
the receipts we get from steam are about one-half profit. It does not
require any additional attendance. It is simply the interest on the
investment on the plant, and the slight additional fuel it requires.

Report Central Illinois Light Company

hot water heating service in Springfield by July, 1956. About 460
customers are affected, and it is expected that the majority may
substitute gas space heating, which will result in operating economies for
both the Company and the customers.
