Central heating

Two concepts coexist under the name of Central heating:

In a room of mechanics, one or more Chaudière S generates the energy. This Chaleur is conveyed by a coolant, in general of water, worms of the serpentines for the systems with hot air, and/or of the Radiateur S, Convecteur S, Aérotherme S.

For a system of central heating on a district or city scale, one will rather use the terms of “district heating”, “heating of district” or “remote heating”. The industry which uses much energy at the time of having surpluses and/or residues of energy that it can sell with peripheral industries or even at very close cities. One qualifies the latter of systems to Co-generation.

The Co-generation, the district heating and the heating of district generally have a distribution of energy by a vapor pipe network. This vapor can be produced by large power stations equipped with steam boilers. Certain networks are fed with the heat produced by a central of incineration of the household refuse. These power stations are rather located outside the downtown area.

The principle of the distribution of heat in the building remains the same one except that inside the building the room of mechanics sees the boilers replaced by exchangers of heat. The exchangers transfer energy from the vapor provided by the city or industry (primary distributers), with the district distributers of heating of beat.

The towns of New York, Montreal and Paris have systems of district heating or district.

The vapor is sold to the subscribers. The vapor passes by the meters among customers who are invoicees according to the consumption of the number of cubic meters of vapor used by each one of them.

The heating of district makes it possible to decrease the concentration of the by-products of combustion in the center town. It offers in premium the occasion to recover energies which would be differently wasted.
