A Geothermal Heat Pump is an electrically driven pump that pumps up and absorbs the energy stored in the earth through heat exchange and moves this energy around, either into or out of the home or building to achieve either heating or cooling.
At our average US latitude the temperature of the earth is a constant 60°-65°F starting at a depth of about 6 feet or deeper. A heat pump will move this heat energy from one area to another. Heat pumps have the ability to move vast amounts of energy at very little cost.
The heat exchange is accomplished in the "ground loop", a polyethylene pipe buried either horizontally or vertically, depending on the terrain and available space. This "ground loop" has proven the most recent technical advancement in heat pump technology. The idea to bury pipe in the ground to gather heat energy began in the 1940's but its only been in the last few years that new heat pump designs and improved pipe materials have been combined to make geothermal heat pumps the most efficient heating and cooling systems available.
Economics of a Heat Pump
A heat pump can move 3.5 to 4.5 times more heat to or from a building than the energy required to operate it. The COP or Coefficient of Performance of the system is the ratio of energy output to energy input. The higher the COP rating, the more efficient the system is. In comparison the COP of an electric furnace is 1 while that of most heat pump systems is 3.5 or more. The heat pump supplies more than 2/3 of your in-home energy requirement from free energy stored in the earth and reduces your energy bills by as much as 70%
Hot Water
One of the many features of a geothermal system is the Desuperheater with the ability to provide "free" hot water during summer (high temperature) operation. In winter savings are still about 65-70% compared to that of heating electrically. This feature will save 20 to 30% on the current electric bill alone.
Environmentally Responsible
The heat pump is also environmentally friendly since no combustion occurs on site where it is used. Fossil fuels are no longer required. The only direct energy input required is electric current to run the pump. If the source of electrical supply is either hydro electric, wind or solar then the energy to supply the home is completely non-polluting or a zero environmental footprint.
Principle of Heat Pumps
Although the term heat pump is relatively well known in the world of HVAC, it is new to most people in the residential heating business, despite the fact that the technology has been around for decades. A heat pump should be seen as a refrigeration device.
If a refrigerating device is primarily used for cooling, it is considered a cooler. Similarly, if its prime function is to produce heating, then it would be called a heat pump. In actual fact a refrigerating device that delivers both heating and cooling is correctly termed heat pump.
Take for example the refrigerator in the home. The food inside is cooled while the coils at the back of the unit heat up. Most of us have noticed the heat from these coils and perhaps wondered where it came from. All refrigerating devices produce heating and cooling simultaneously. Therefore the industry designates a refrigerating device by its method of utilization as either a heat source or air conditioner.
The principle of the "heat pump" or refrigeration machine dates back to the 18th century and Lord Kelvin, a prominent British scientist. In 1918, Kelvinator Company marketed the first automatic refrigerator and in 1926, General Electric introduced the first "hermetic'' or sealed compressors, a design which is still in use today. During this same period, Carrier Co. successfully introduced automatic refrigeration units for comfort cooling. Since this time industrial and economic growth has been phenomenal.
In future, heat pumps will play an even larger role in heating than they have done in cooling.
Selecting a Heat Pump for a Particular Region
During the last several years it has become much more common for homeowners to choose a heat pump system as the prime heating and cooling source for their home. Local climate determines the type of system most suitable. Although a variety of systems exist with applications anywhere from the high North to the deep South, we will settle for the systems most commonly used in the US Southwest.
We will assist in determining the best system for the desired location offering the highest COP attainable at the best price. For example a COP of 3.5 means that the heat pump will give-out 3.5 times as much heat-energy for a given amount of electrical heat energy.
