How Does a Boiler Work

This post explains How Does a Boiler Work. A boiler is a water-containing vessel that transfers heat from a fuel source (oil, gas, coal) into steam which is piped to a point where it can be used to run production equipment, to sterilize, offer heat, to steam-clean, etc.

The energy provided by the steam is sufficient to convert it back into the form of water. When 100% of the steam produced is returned to be reused, the system is called a closed system. Examples of the closed systems are closed steam heating, hot water heating, and the one-pipe systems.

Since some methods can contaminate the steam, so it is not always desirable to feed the condensate back into a boiler. A system that does not return the condensate is called an open system.

Heating Boiler

  • Your home’s thermostat senses a drop in the home’s temperature and calls for the boiler to turn on.
  • The boiler powers on and the uses either oil, gas or the electricity to create heat.
  • The heat from the fuel source is used to heat up the water inside the boiler.
  • The heated water or steam is sent throughout the home where it gives off its heat to warm the air.
  • As the water cools, it travels back to the boiler where it’s reheated and sent back out to continue heating your home.
  • This method continues until the home reaches the set temperature and your thermostat calls for the boiler to turn off.

The boiler is an important part of the central heating system. It’s like a big fire that has the continuous supply of natural gas streaming into it from a pipe that goes out to the gas main in the street. When you need to heat your home, you switch on the boiler with an electric switch.

A valve opens, gas enters a sealed combustion chamber in the boiler through small jets, and the electric ignition system sets them alight. The gas jets play onto a heat exchanger connected to the pipe carrying cold water. The heat exchanger takes the heat energy from the gas jets and heats the water to something like 60°C (140°F).
