The geothermal heat pump system is probably one of the most notable innovations of recent times in the field of heating and cooling. These heat pump systems work in a similar fashion to that of the traditional refrigeration systems with fluids inside a network of pipes that is used to dissipate or absorb heat from the surrounding. However, unlike refrigeration that uses the surrounding air of its outside atmosphere to maintain its temperature requirements for american standard home services, the geothermal heat pump systems work at an underground level.
Temperatures at about 10 feet underground remain constant irrespective of the changes in weather above ground. This approach, offers a greater efficiency to the system, and can heat and cool faster since the unit is not combating ambient temperatures.
As far as statistics go, these ground source geothermal heat pump systems are capable or performing at efficiency levels that are at least 400x more efficient than the best air conditioners available in the market, and 200x better than most gas furnaces in the market. These devices can work with one kilowatt/hour of energy to produce 12,000 BTU of cooling and heating, compared to 2.2 Kilowatt/hour energy required by most other standard systems to produce the same amount of output.
These systems are widely recommended by the EPA, various environmental groups, and energy-conscious associations. For instance, the Environmental Protection Agency of the United States recommends these geothermal energy systems are the most energy efficient, environmentally friendly, and money-saving space conditioning devices available to date. Geothermal systems are heavily favored for many reasons. Here are some of the top geothermal heat pump advantages:
Although these systems are initially expensive, they end up costing much less than other traditional systems.
The geothermal heat pump price comes up to around $2500 per ton of their capacity, so that for an average three ton, you would spend $7500 initially. A similar size of air conditioner would on the other hand cost you $4000 roughly. However, these geothermal heat pump systems are capable of saving 30 to 70% energy consistently. So that on an average yearly energy bill of $1500 you could be saving in between $450 to $1050, effectively breaking even on the cost front within the first 4-8 years.
While traditional air conditioners usually would not last you beyond that eight year period (and in many cases far less), these geothermal heat pump systems are known to provide consistent performance for as long as fifty years. They are not only durable they require very little maintenance and sometimes even zero maintenance. In fact, the loop fields under ground are often guaranteed for 25 to 50 years, while scientists say they could potentially last till more than 100 years.
These systems are environment friendly and reduce the emission of greenhouse gases by an equivalent amount of 750 trees. There is no combustion in these systems, which means no emissions into the environment.
They are very quiet.
Like central air-conditioning these system uses ductwork to heat and cool spaces. A geothermal system hooks up to the same ductwork, undetectably maintaining comfortable temperatures year round and also maintain humidity balance naturally.
Since the unit is stored inside, and the lines are buried underground, there is no cosmetic degradation to the exterior of the home or building.
Theft is also thwarted to do its set-up.
With a de-superheater, a geothermal system can also be used to heat/cool water.
A geothermal system can also be configured for radiant flooring, to heat floors throughout the house.
