Explanation of Hot Water Heating Systems Hunker

Water is heated by a boiler and circulated throughout a building--usually homes (older homes, especially)--through a series of pipes that heat radiators that give off heat. The heat transfers to the air in the room. There are three basic types of hot water heating systems: gravity flow, pumped and baseboard convection systems.

Forced-Circulation Reboilers Process Hydrocarbon …

Forced-Circulation Reboilers Process. without comments. Figure 7.6 shows a once-through forced-circulation reboiler. Such a reboiler differs from a thermosyphon reboiler in that it has a pump to force circulation, rather than relying on natural or thermosyphon circulation. This extra pump seems rather wasteful—and it is.
