How do boilers transfer heat from the burner to the room

Convection helps to move the water through the piping system. Warm water tends to rise and cool water tends to fall, since it's heavier. Gravity water heating systems rely exclusively on convection to move water through the piping system. Boilers also use convection to transfer heat from the radiators into the rooms.
