One has to finish the job: a stupid way to complete the cycle would be to let the steam escape into the air, for then one has to keep supplying water. It is cheaper—more efficient—to let the steam go into another box, where it is condensed by cool water, and then pump the water back into the boiler, so that it circulates continuously.

Selecting a Home Heating System - Energy Depot

The water vapor in the exhaust is condensed, releasing additional useable heat, and lowering the exhaust temperature to the point where it can be vented outdoors via a plastic pipe. Although this type of system is more expensive, it is often the most cost-effective option in cold climates or large homes with high heating requirements.

Water - Wikipedia

Water (H2 O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, nearly colorless with a hint of blue.This simplest hydrogen chalcogenide is by far the most studied chemical compound and is described as the "universal solvent" for its ability to dissolve many substances. This allows it to be the "solvent of life": indeed, water as found in nature almost
