How does a hot water heating system work?

We can think of a central heating system as acontinuous circuit moving hot water out from theboiler, through all the radiators in turn, and then backagain to pick up more heat. The heat energy from thegas is transferred to the water. An electric pump pushes theheated water through the system.
