As a result of this heat transfer, some of the saturated steam will condense as it travels around the pipe loop, returning the state to within the vapour dome. The. amount of liquid in the mixture will increase the further the water flows from the boiler, reaching a maximum where the pipe loop reenters the boiler to complete the cycle.

Gas-Fired Boilers - Code Compliance Brief | Building

Whereas a furnace directly transfers heat from combustion to supply air in the air distribution unit, a boiler heats a secondary transfer fluid (typically water, but sometimes steam) that is, in turn, pumped through a radiation/convection system located throughout a building or home. The hot water can also be used to heat air via a coil and blower.
