Geothermal

Geothermal Heating & Cooling LoopsWhat is Geothermal Heating & Cooling?

The earth absorbs almost 50% of all solar energy and remains a nearly constant temperature of 50°F to 70°F depending on geographic location. Working with an underground loop system, a Carrier geothermal unit utilizes this constant temperature to exchange energy between your home and the earth as needed for heating and cooling.

In winter, water circulating inside a sealed loop absorbs heat from the earth and carries it to the unit. Here it is compressed to a higher temperature and sent as warm air to your indoor system for distribution throughout your home.

In the summer, the system reverses and expels heat from your home to the cooler earth via the loop system. This heat exchange process is not only natural, but is a truly ingenious and highly efficient way to create a comfortable climate in your home.

Major Benefits:
  • Efficiency
  • Comfort

Geothermal heat pumps are 3.5 – 5 times as efficient as the most efficient fossil fuel furnace. Instead of burning a combustible fuel to make heat, they simply move heat that already exists. By doing so, they provide 3.5 – 5 units of energy for every unit used to power the heat-pump system.

In winter, a Geothermal heat pump system moves warm air throughout your home via a standard duct network. Typical, a very even comfort level is found throughout the home. This is because the warm air is moved in slightly higher volumes and, therefore, saturates the home with warmth more evenly. This even helps out hot or cold spots and eliminates the hot air blasts common with fossil fuel furnaces.
  •  Cost
A system for the typical home will cost more than if you bought a separate forced-air furnace and central air conditioning system. But you wouldn’t be comparing “apples to apples”. To get an accurate comparison of cost you need to consider the following:
  • Payback, or how long it takes to recover the difference in cost between the two systems using energy savings. Payback for most Geothermal heat pumps systems runs 3 – 5 years.
  • Energy efficiency of the two systems. To get an accurate picture, make efficiency claims are substantiated. Your lifestyle and how well your home is insulated affect how economical a system will be.
  • Total operating savings from heating, cooling and domestic hot water must be combined to get an accurate picture of total energy savings.
  • Energy costs and availability, both present and future.
  • Maintenance cost and system reliability.
  • System lifespan.
  • Carrier Geothermal software can calculate annual operating costs for geothermal systems and compare to other technologies.
