Geothermal Heat Pumps | HVAC Heating & Cooling
Geothermal heat pumps use ground water or water circulated through pipes to exchange heat with the earth. Geothermal, versus air source heat pump systems, use the earths natural temperature to exchange heat and provide heating and cooling. The temperature of the air varies widely with the weather whereas the temperature of the earth is nearly constant and makes the use of a geothermal system ideal for heating and cooling your home or business. It also costs less in energy use because of the constant earth temperature versus the widely varying temperature of the outside air. Geothermal systems make sense and can save lots of money in energy use.
Geothermal Heat Pumps - Operating Costs
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 can be offset by the savings in energy usage over a period of time making these systems 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. Ground source systems can be a solution to save energy costs in the future. There are some considerations you need to know about having a geothermal system installed for your home or business.
Geothermal Heat Pumps - RequirementsFirst you need to have a source of water in a large body or a well that can handle the load of a geothermal system. 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 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 installation cost.
Geothermal Heat Pumps - 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.
