Thanks Jon. I am still trained to believe electricity is prohibitively expense...bcause it is in my city/area. What do you pay per Kwh, taxes and all?
Garbriele:
How far away is the plant that heats your water? Would you say buying water that is already hot is less expensive than heating it in your own home? How about with electricity? and with methane/gas?
The island of Manhattan is the center of Downtown New York City. There steam can be bought form the local utility company (ConEdison => Consolidated Edison). You can't put a boiler in the basment of a skyscraper because by the time the flue got to the top of the buildng, the gasses would be cold and the moisture would all condense, rotting the chimney and flue. If one were to dump the by-products of combustion out the side of the buildng, it would be hitting someones else's window; not good. You can't easily put a boiler on top of a skyscraper because getting the gas or oil to the top takes vast amounts of pipe, pumping and is dangerous. Such a location is also otherwise impractical. Steam, then, at any price is what works!
