It is an important part of our commitment to preserving our earth and conserving its resources for future generations to enjoy.We deliver top–quality heating oil from our own 400,000 gallon storage facility to your home in Brooklyn, Manhattan, Queens, The Bronx or Long Island.To order hard copies of the Briefs, see Printed Publications.The need for modern mechanical systems is one of the most common reasons to undertake work on historic buildings.Air is pushed through the heat exchanger by the “air handler’s” furnace fan and then forced through the ductwork downstream of the heat exchanger.
By regulating the ambient temperature, heating also serves to maintain a building’s structural, mechanical, and electrical systems.
A more common form of heating in modern times is known as central, or indirect, heating.
It consists of the conversion of energy to heat at a source outside of, apart from, or located within the site or sites to be heated; the resulting heat is conveyed to the site through a fluid medium such as air, water, or steam.
Some of the web versions of the Preservation Briefs differ somewhat from the printed versions.
