  • Boilers Versus Furnaces: What's the Difference? | Carrier

    Boiler vs. Furnace: What's the Difference? Both boilers and furnaces burn fuel to help heat your home, but they do so quite differently. Furnaces - also called forced air furnaces - directly heat the air, which is then pushed throughout your home. Boilers heat water, which is sent as steam through a radiator system.

  • What is the difference between a boiler and a reboiler

    Nuclear reactor steam cooling towers seem to mostly condense the steam, but if they need more cooling than the tower can achieve, they just release steam. I would call it a boiler in an open system and a reboiler in a closed system, but the usage isn't always consistent. Either system is likely to call it a boiler.
