Abstract
An excavationless geothermal system for heating and cooling applications includes a potable water storage container that receives water from a water supply through a supply line and a reversible water meter. The water in the storage container is circulated through a heat pump, and when the temperature of the water in the container is increased or decreased by the heat pump, the water is returned to the supply through the reversible meter.
Claims40
A geothermal system, comprising:
- a water storage container;
- a heat exchanger thermally coupled with said storage container;
- a water inlet leading from an underground potable water source to said storage container for supplying potable water to said storage container;
- and
- a water pump connected to said water inlet for returning potable water from said storage container to said underground potable water source through said inlet.

A geothermal system for heating or cooling space, comprising:
- a water storage container connected to receive potable water from a potable water source;
- a heat pump connected to said container and in heat exchange relationship with water stored in said container;
- a water pump connected to said container for returning water in said container to said potable water source;
- and
- a reversible water meter connected between said potable water source and said container and between said water pump and said source.

A geothermal system for heating or cooling a space, comprising:
- a water storage container connected to receive potable water from a pressurized water source;
- a heat exchanger connected to said container and in heat exchange relationship with water stored in said container and with the space to be heated or cooled;
- a water pump connected to said container for periodically returning water in said container to said source;
- a single water inlet pipe connecting said container and said pump to said source, and single pipe supplying water from said source to said container and returns water from said pump to said source;
- and
- a reversible water meter connected in said single water inlet pipe.
