A geothermal heat pump is a system buried under the lawn as a promising solution to high energy costs. This home renovation technology gives clean and quiet cooling as well as heating while reducing electricity bills by up to 70% allowing a home owner to sit on top his energy supply for a lifetime.
As with traditional heat pumps, geothermal heat pumps utilize a high-pressure refrigerant in capturing and moving heat between outdoors and indoors. However, geothermal systems move heat through the use of liquid-filled pipe loops that are buried under the ground. These systems are special as they are paired with the earth instead of the outside air. Its medium to transfer heat is water.
The ground’s renewable solar energy is used by a geothermal heat pump in order to offer up to 70 percent savings on cooling and heating costs. Outdoor air temperatures are varied from winter to summer or from day to night while the temperature below the surface of the earth remains 57 to 70 degrees Fahrenheit on average all throughout the year.
In cooling a home, a common heat pump system gets indoor heat and releases it outside. Unluckily, temperatures in the summer can reach up to 90 or 100 degrees, thus, heat already fills the outside air which may not accept more. This exchange process is likely to become more difficult resulting in an ordinary heat pump becoming least efficient when needed.
To warm homes, a regular heat pump gathers outdoor heat from air and transfers it indoors. But as temperatures drop in the winter, there is not much heat to gather. A geothermal unit like those found at GNR Corbus chauffage does not need cold winter air as it gets it from a reservoir of temperatures as warm as 57 degrees and then concentrates it and transfers it to homes.

A geothermal unit does not see hot air in the summer. This gets heat from homes and transfers it to the earth’s 50 degrees heat. Regardless of the fluctuation of the outdoor conditions, the ground remains stable because of the earth’s constant temperature. This allows geothermal heat pumps to be more than two times as efficient as air conditioners at cooling homes.
Environmental agencies in the world recognize the energy efficiency and cost-effectiveness of geothermal heat pumps in terms of cooling and heating. These pumps are helpful for electric utilities in achieving substantial demand load reductions. As the electric utility demands are reduced, geothermal systems minimize the need for power plants generally powered by natural gas or coal. Also, a home with a typical area of 2,5000 square feet that has a geothermal system can surely save electric utility company over 90 tons of coal every year.
Such systems also reduce the risks of air pollution, greenhouse effect, acid rain and global warming issues associated with fossil fuel burning. Environmentally speaking, installing one geothermal unit is the equivalent to planting 750 trees. A lot of those who wish to improve the efficiency of their homes prefer to have this system in place to make sure that they have a healthy spending on their cooling and heating systems.
