Geothermal heat pumps provide you with heating and cooling at nearly half the energy cost that standard air conditioner and heating systems or air source or gas or oil systems cost to run in the typical residential or light commercial setting. The high installation costs of geothermal heat pumps can be offset by the savings in energy usage over a period of time making geothermal heat pumps ideal for the present and future use. Energy costs are rising every year as finite resources become limited and the world population increases demand for energy geothermal heat pumps can be a solution to save in energy costs in the future. There are some considerations you need to know about having a geothermal heat pump system installed for your home or business.
First you need to have a source of water in a large body or a well that can handle the load of a geothermal heat pump. In some cases, if you have a large area of land, a trench can be dug and special geothermal heat pump piping can be installed in the trench to provide a water loop for the geothermal heat pump system. The cost of have a well drilled, trench dug, or piping ran to a large body of water can make the installation cost of the geothermal heat pumps rise well above the normal air to air heat or cooling systems however the energy savings realized over a period of time by utilizing a geothermal heat pump system can offset this high geothermal heat pump system installation cost.
Features and Options
A geothermal heat pump system can come as a split system or it can be a single packaged unit. A geothermal heat pump system will still require the installation of duct work because geothermal systems are forced air systems. An added benefit of a geothermal heat pump system is that some geothermal heat pumps can be fitted to heat water for domestic use so you can use your geothermal heat pump to heat water for your shower and washing dishes. Other geothermal heat pumps are water to water and can produce hot water for a radiant heating system, used as a pool heater, or used in snow melting. Geothermal heat pump systems are all electric and considered to be more efficient than other forms of heating and cooling.
Geothermal heat pumps can be open loop, closed loop, or use a large body of water for the heat exchange process from the Earth. Closed loop systems can be installed either vertically or horizontally if there is enough land for a horizontal installation. Open loop geothermal systems require two or more wells where one well receives the water from the geothermal system and the other well pulls water from the well for the geothermal system. Special piping is used in all applications and when a large body of water is used for the geothermal systems the piping is secured under the water below the average freeze line in the water. Ground source heat pumps.
Here is an excellent video of how a geothermal system heat pump works. Lengthy video and intense discussion of a geothermal heat pump system but very good. Geothermal heat pump systems are the most efficient systems used and do not require back-up heat like an air source heat pump system. The cost of installing a geothermal heat pump system is higher but over the long term the savings in energy usage from a geothermal heat pump system to an air to air heat pump system is greater. The discussion includes the payback in energy savings from the cost of installing a geothermal heat pump system.
