There are only a few states where the homes can get away without having a furnace, but not many. The most common method of heating homes is central heating in Greenwich CT. This central unit produces heat by burning fossil fuel inside a metal fire box; the medium is either hot air or hot water. In the case of hot air, the heat is distributed to all the rooms in the house though a ducting network, heated air is delivered through one network and cold air is returned to the furnace through a separate duct network. In the event the medium is water, hot water is distributed through a piping system which takes hot water to a series of radiators, normally one or two per room. The most common fuel is natural gas, but central heating in Greenwich CT can also burn oil, coal or wood.
Central heating differs from unit heating inasmuch as all the heat is generated in a single furnace and then distributed. This is by far a superior system; fuel only has to be supplied in one central place. Fireplaces, although they are lovely to look at and do provide great ambiance are not efficient as a great deal of the heat goes straight up the chimney. Fireplaces also draw cold air from the outside which tends to make rooms on the perimeter of the house much colder than those in the center.
Central heating has been done for many hundreds of years, and although the modern system is very sophisticated when compared with old systems, the concept has not changed. A furnace is not particularly complicated but it does have some essential components. In the typical central heating furnace, the heating takes place in the core of the unit and the ducts leave and return through the top and bottom.
The heat supply duct is at the top of the furnace, if necessary a humidifier can be installed at this point. In the middle of the furnace are two pipes, one supplies air for fuel combustion and the other is for removal of the exhaust.
The return ducts all terminate at the bottom of the furnace, this cold air is drawn from inside the house for heating. In most cases the return air duct is fitted with a filter which cleans the air before sending it back through the system as heated air.
