Geothermal heating is a method of heating and cooling a building. It takes advantage of the natural stable warmth stored in the earth. Normally the earth is around 55°F (12.8°C). This is accomplished by one of a number of methods. A heat pump uses the extracted water or transfer fluid as a heat source in winter and a heat sink in summer. Some systems use part of the heat to heat the building's hot water. HVAC may also stand for High-voltage alternating current HVAC is an initialism that stands for heating, ventilation and air-conditioning. This is sometimes referred to as climate control. ... A heat pump is a machine which moves heat from a low temperature reservoir to a higher temperature reservoir under supply of work. ... A large copper heatsink. ...
Types of geothermal systems
Long, shallow loops buried in the ground
Pipes circulating fluid through or drawing water from a nearby body of water
Deep wells - usually two or more wells over 200 feet deep
Either of these systems can be either open-loop or closed loop. In a closed system, water and antifreeze (or other transfer fluid) is circulated through the heat exchanger and back out through the loops continuously. In an open system, water is drawn from depth in a deep well system or from a body of water in a shallow system. Once this water passes through the heat pump, it is released back to its source, generally as far from the intake as possible. Some closed loop systems bled off a portion of their working fluid to keep the source temperature stable. The Whole Earth Lectronic Link (or The WELL) is one of the oldest virtual communities still online. ...
Geothermal heating is one of the most efficient ways to heat a building but it has high initial costs for drilling the wells deep enough into the earth to take advantage of the earth's temperature. It also has ongoing costs for the electricity to power the pump and heat pump. An electric drill A drill is a tool with a rotary drill bit used to bore holes through material. ...

Some actually useful information, including DIY cookbooks: http://geoheat.oit.edu/pdf/pdfindex.htm
A geothermal apparatus comprising a first pipe for receiving a heat exchange liquid therein and a second pipe for receiving the heat exchange liquid therein and having a web integrally connected to each of the first and second pipes, between such pipes for holding the second pipe at a predetermined distance from the first pipe.
The geothermalheating and/or cooling system of claim 4 wherein the integral attachment is continuous between the first and second pipes for a substantial distance of the first and second pipes.
The present invention relates generally to a geothermalheating and/or cooling system and more particularly to one having a first pipe and a second pipe which are integrally connected together and, in a preferred embodiment, one piece by an extruded process.
Geothermalheating is based on a very simple concept, the temperature of the earth at a given depth is always constant no matter what the conditions outside.
Based on the geothermalheating requirements, the length and capacity of the loop fields vary, the bigger the structure the bigger the length and capacity of this geothermalheating component.
The heat pump is the most essential component of the geothermalheating system, the heat pump actually converts the warm water or liquid it receives based on the requirement, into warm air, or allows the warm water to flow forward for various purposes.
