What is central heating system?

Central heating system refers to a single heating appliance which can be used centrally for every area. For instance, boiler is a central heating system which is fitted into your kitchen but pumps up the hot water to your bedrooms bathroom, utility room and other places with the help of radiators situated in your rooms.

How does a central heating works?

  1. Natural gas enters into the home with the pipe and all the heat that will be used to warm your house will get store inside the gas in the chemical form.
  2. Then the gas is burnt by the boiler to make the hot jets that play on the heat exchanger. This heat energy is transferred to the water.
  3. An electric pump attached with the system pushes the heated water upwards.
  4. The water than flows around a closed loop inside the radiator, entering one side and leaving the other.
  5. As soon as the water cools down, it has to return to the boiler to pick up the more heat.
  6. Water acts as a heat-transporting device that collects the heat from the boiler and delivers it to the radiators.
  7. The pump uses it full force to push the water upstairs through the radiators.
  8. A thermostat is available in one room, regulates the temperature and switches off the boiler off when it is hot enough
  9. Also it switches on the boiler when the room gets too cold.
  10. Waste or harmful gases from the boiler, leaves through a small smokestack called as a flue and disperses in the air.

What are radiators?

Radiators as the name suggests not only give the radiant heat, they deliver most of their heat through convection. However air warmed by the radiator naturally rises and cools down, as a result the warmed air circulates and the space in the room is warmed.
