How does a combination boiler work?

A combination boiler is connected to the mains water supply. When a hot water tap is turned on, gas burner is ignited, and a heat exchanger transfers the energy to the water. The exchanger allows hot water to be generated almost immediately, for hot water on-demand at any time of the day.
