Boilers help make the steps between turning the heater on and enjoying comforting warmth seem easy. But there’s a lot of work going on.

1. The user turns on the heater, opening a valve in the boiler through which gas enters a combustion chamber. 
2. An electric ignition system ignites the gas entering the combustion chamber.
3. The resulting flame warms cold water that’s in a pipe connected to the heat exchanger. 
4. An electric pump moves the heated water through piping that wends its way around a house or office space. 
5. As the heated water flows in the piping, it moves through radiators in various rooms and gives off heat that warms the space.
