A Central heating system aims at providing uniform heating throughout a building. Central heating is quite different from traditional local heating devices like furnaces or mechanical heating devices which are mainly restricted to just one particular place.
Generally three kinds of systems are used in any central heating installation. These are:
Forced air heating: In this particular system ducts and air blowers are used for circulating air. This device works on a very simple concept in which the blower pumps air into the room through the ducts and at the same time the cooled air from the room is drawn back to the furnace through another set of ducts. Upon reaching the furnace, the cool air is once again warmed up and the entire process is repeated. The ideal place for installing these devices is any closed space like a basement area, closet or even a garage. The main benefit of using this system is that a centralised air conditioning system can be attached to it.
Water heating: This system includes a boiler that is used to heat water and then circulate it. Heated water is generally circulated through one or two pipes or a series of loops. This system comes with radiators which are used for pumping in hot water and withdrawing cold water to the boiler. Three kinds of radiators are used in this system- vertical tube, cast iron and baseboard. Of these, the first two are installed standing on the floor while the third kind is placed at ground level within an enclosure.
Combination heating: This is the third kind of heating system and, as the name suggests, it uses a combination of heating and cooling systems in one pack.
How do these work? Generally central heating equipment is available in many various forms in the market. Some of these are furnaces, boilers and heat pumps. An electric furnace comes with wire strips that are heated by power. The fan present blows hot air through the strips which in turn is circulated in the room with the help of a blower.
In the case of a gas unit, a burner pumps gas which is ignited to generate heat. This heat is transferred from the heat exchanger to the room and the waste gases released are sent out through the vent pipe.
An electrical heating system is used both during winter and summer. In winter this electrical heating equipment extracts heat from the outside atmosphere and pumps it into the room. Vice versa during summer. Generally in winter the pump uses an outdoor coil containing liquid refrigerant. When air is blown across this coil, heat is absorbed by the refrigerant which upon conversion to hot vapour is pumped through an indoor coil. As the vapour pumped is hotter than room temperature, it gets condensed and heat thus generated is used for heating the room. The same process is reversed in air conditioning. Thus central heating systems really aren’t as complicated as they sometimes seem.
