How Geothermal Heat Pumps Work

The HVAC industry is constantly looking for ways to expand, refine and improve renewable energy equipment. Traditional gas or electric powered forced air furnaces and air conditioners have been the standard for the industry for decades, but there is little doubt that tapping into all that renewable energy sources have to offer can potentially lower energy costs and be eco-friendlier to our planet. Masters Heating & Cooling Inc. is excited to provide renewable energy HVAC solutions that make sense for our customers, both residential and commercial and that’s why we are going to take a look at geothermal heat pumps.

GEOTHERMAL ENERGY

One of the most stable and readily available renewable energy options are geothermal heat pumps. The main reason for this is that it utilizes one of our most abundant natural resources: the earth. Beneath the earth’s surface, the temperature is a steady 50 to 60 degrees. The geothermal heat pump technology takes advantage of this constant source of heat and uses it to provide energy for many uses, including indoor climate control and domestic water heating.

GEOTHERMAL HEATING

The origins of geothermal heating technology can be traced to Lord Kelvin in 1852, with significant modifications taking place at the turn of the 20th century and residential/commercial implementation beginning in the United States in the 1940s. After the global oil crisis in the 1970s, geothermal heat pump systems were embraced worldwide. 

A geothermal heat pump system generally includes a series of loops that are embedded in the earth around a home or building. These loops are filled with a water solution which absorbs and transfers the heat energy into your home. The heated water is transferred into your home, where your heat pump extracts the warmth and circulates it through your system’s ductwork. During the summer, it does the opposite: the heat pump removes the hot air from your home via the loops, which transfers it to the earth, cools it down, then returns it to your home. This heat energy can also be used to heat water in your home for domestic uses. According to the Environmental Protection Agency, geothermal heating can reduce energy bills by as much as 50 percent and are nearly 50 percent more efficient than gas furnaces. Because geothermal heat pumps do not burn fossil fuel, there are less harmful emissions, including complete elimination of poisonous carbon monoxide gases that are a byproduct of conventional heating systems. 

Geothermal heat pump systems are not viable options for everyone, mostly due to an initial installation cost that includes extensive excavation around existing homes. On the other hand, it makes great sense for new home construction or renovations for homeowners or business owners interested in making a long-term investment.
