ABSTRACT:
This relates to a heating system which may be utilized conventionally for the heating of homes or the like. The heating system incorporates a conventional well having a casing extending above the level of the water in the wall and wherein a sufficient vacuum is drawn in the casing above the water level so as to cause the water to boil at approximately the temperature of the water in the well. The pressure of the water vapor is then raised in the vacuum pump to a pressure substantially atmospheric or slightly above, at which time the water vapor temperature rises to approximately 212.degree. F. The high temperature water vapor is then directed through a condenser where it is condensed back into water and is returned to the well or some other area. The condenser may be utilized for the transfer of heat to heat the house or other unit being heated.
