Geothermal heat pumps are becoming an increasingly popular option as they allow a much more energy efficient heating option for homeowners. However, when choosing the geothermal pump that is right for your needs, you should take a few items into consideration. Not all styles of heat pumps are the same, and though these can provide you with a renewable heat source and benefit you in lower costs, the decision to go with a closed loop or open loop system may impact those savings even further, depending on your situation and needs.
Geothermal Heat Pumps
Geothermal heat pumps, which are also known as GeoExchange, ground-source, and water-source heat pumps, utilize consistent ground temperatures as a means to exchange heat, a much more effective and efficient model than models that us outside air. The constant temperature beneath the ground allows for a steady rate of heat exchange with little variation no matter the season, and can supply users with easily maintained and affordable heating and cooling. If properly equipped, a geothermal heat pump can even supply a home with heated water.
The one drawback of geothermal heat pumps is their installation costs. When compared to traditional heating and cooling systems, ground-source heating and cooling could prove to be cost-prohibitive to some customers. However, one factor that should be taken into account when considering water-source or earth-coupled heat pumps is that the energy savings will greatly off-set the installation costs in the long run, making it a much more effective and preferable option.
The Types of Geothermal Heat Pumps Include:
- Closed-loop Systems
- Open-loop Heat Pumps
- Dual-source Heat Pumps
- Horizontal Heat Pumps
- Vertical Systems
- Pond/Lake Heat Pumps
- Hybrid Systems
Closed-Loop Geothermal Heat Pumps
The primary difference between closed-loop heat pumps and typical water-source or open-loop geothermal systems, is that open-loop systems use either well or surface water as a method of heat exchange. If a home does not have access to two wells of ground water, this can become much less practical of a solution. The water also must be clean and groundwater regulation codes must be met. If a home has the needed wells, then this can prove to be an incredibly economical solution, but going the closed-loop route can provide an option if that is not the case.
The way a closed-loop heat pump works is by utilizing an antifreeze solution that it circulates through a closed loop of pipes and plastic tubing that is buried under ground or in water. This setup allows for a heat exchange between the two, and allows a variety of configuration options, including use of a horizontal, pond, lake, or vertical setup. A closed loop system has the advantage of being quite safe, and water contaminant issues never being a problem.
Closed-loop geothermal heat pumps are an advantage for Troutman home owners in that they can be installed at nearly any location, and do not have the limitations that open-loop pumps suffer from. Though they may be slightly more expensive than an open-loop system as far as installation, they will prove to be just as effective at regulating temperatures, and can render a home owner the same degree of savings.
If you are looking for a more environmentally friendly heating and cooling option that will cut back on your energy expenses for years to come, then you cannot go wrong in making the transition to a geothermal heat pump. The installation costs are completely negligible when compared to the savings that can be rendered from making this transition in the long run.
