Heating system

摘要

A heating system for baseboard location has a chamber partly filled with liquid and sealed for holding a vacuum. A heater in the chamber heats the liquid into vapor to heat the chamber. First and second heat exchange plates extend annularly and substantially horizontally about the chamber with inner peripheries in heat-conducting contact with the chamber. The first heat exchange plate has at least one airflow hole therethrough on one side of the chamber and the second heat exchange plate has at least one air-flow hole therethrough on another side of the chamber. A space between the first and the second heat exchange plates is enclosed at the outer peripheries of the plates.
