Geothermal Heat Pumps Offer a Greener Cooling Option

If you’re looking for an efficient way to heat and cool your home, a geothermal heat pump is an option worth considering. The basis for this technology has been around for thousands of years, and today’s geothermal technology makes it possible to keep your home comfortable year round without high energy costs.

How a Geothermal Heat Pump Works

If you walk into a cave and go underground, you may notice that the temperature tends to remain the same, no matter what time of year it is. Though the temperature may range from 45 to 75 degrees, it remains relatively constant. It’s this consistency that makes the geothermal systems work.

To install a geothermal system, the HVAC contractor lays a network of piping in the ground at a depth of six feet or more. The pipe, which contains either water or a water/refrigerant mixture, connects to the heat pump. As the heat pump circulates the liquid through the pipes, the ground temperature adjusts the temperature of the liquid within the pipe.  As the water returns to the heat pump, the change in temperature helps heat or cool your home.

Benefits of a Geothermal Heat Pump System

The efficiency of a geothermal system is the main reason homeowners install them. The system can run year-round with much lower energy costs compared to a standard heat pump, furnace or central Air Conditioning system. In addition to lower heating and cooling costs, you can also use a geothermal system to heat your home’s water.  While installation costs for a geothermal heat pump are higher than for a standard system, you can recoup those costs in just a few years.
