Can a Geothermal Heat Pump Water Heater Save You Money?
While the air temperature in the Atlanta area may fluctuate wildly over the course of the year, the temperature just below the ground stays about the same. Geothermal heat pumps (GHPs) take advantage of these constant, pleasant conditions a few feet below the earth to deliver energy to your home. As a result, heating and cooling is done far more efficiently, allowing you to save on water heater and other HVAC costs. Here is how the system works and potential savings in energy and money it can give you.
How Geothermal Heat Pumps Work
Instead of trying to heat or cool a home by manufacturing energy, GHPs take the consistent temperature below the ground and transfer it to your home. As a result, heating and cooling are handled much more efficiently, especially on cold winter nights. According to ENERGY STAR, over 50 percent of a household’s energy use is devoted to heating and cooling. When you add in the energy needed to heat water for showers and laundry, the number jumps to over 60 percent.
Switching to a heat pump system allows you to cut down significantly on the energy needed to meet those demands. While air-source heat pumps represent an upgrade over many systems, GHPs are the most efficient type available. Though this efficiency comes at a higher upfront cost, there are rebates available for many models as well as the long-term energy savings to consider.
Water Heater Savings and Available Rebates
Compared to air-source heat pumps, there are big energy savings to enjoy when opting for a GHP. The U.S. Department of Energy estimates that the energy savings from a GHP will make up for the difference in upfront costs (compared to air-source heat pumps) in 5 to 10 years. Considering the interior components may last 25 years - and the underground loop over 50 years - it is clearly the choice for long-term energy and cost savings.
Rebates for energy-efficient equipment are also available to many area homeowners. For example, Marietta Power & Water customers can receive up to $500 in rebates when replacing a water heater and heating system at the same time. Check the guidelines when you are deciding to upgrade HVAC equipment for more efficient models.
