What is a Geothermal System?

Geothermal heat pump systems are innovative, efficient solutions for homes and businesses regardless of the time of year. Comprised of a heat pump and ground loop, a geo HVAC system uses the natural warmth and coolness of ground temperature – which is 55 degrees year-round – to condition living and work spaces. Our technicians can help you decide if geothermal heating and cooling is the right choice for you.

The video below from the US Department of Energy provides an overview of what a geothermal residential system is an how it heats and cools your home so efficiently.

Comfort Year-Round with a Geothermal Residential Heat Pump

During winter, the water that circulates through a geothermal system’s ground loop absorbs heat, which is then transferred to the heat pump. Once the heat is collected, it’s passed through a space in the form of warm air. In the summer, the system essentially works in reverse. The heat pump captures heat from indoor air and moves it through the loop – leaving only cool air behind.

Affordable

Whether you’re a home or business owner, you stand to gain much from a geothermal heat pump. In contrast to other types of systems, geo HVAC solutions offer greater savings. These systems transfer energy rather than creating it through burning fuel. Accurate Heating & Cooling is fully familiar with a variety of HVAC systems – geothermal included.

Geothermal Residential Heat Pump Technical Information

Heat pumps can be classified by their heat sources. Ground source heat pumps transfer heat from the ground or a body of water to the home (in winter). Geothermal heat pumps are of this ground source variety. Air source heat pumps transfer heat from the outside air to the home (in winter). When a home has a heat pump, it generally means that instead of an air conditioner, the outdoor unit is an air source heat pump.

Further expanding on this, a residential geothermal system uses the earth as a heat source and a heat sink. Heat transfer happens by circulating water in a closed loop or open loop piping system. Open loop geothermal systems use well water as the heat source or heat sink. Closed loop geothermal systems circulate water in underground or underwater piping systems.

Although outdoor temperatures will vary considerably in Nebraska throughout the year, the temperature underground or in a body of water is relatively constant all year. This allows a ground source heat pump to produce consistent heating or cooling temperatures all year long.

Ground Source Heat Pumps

Ground source heat pumps are recognized by the Environmental Protection Agency as preferred heating and cooling methods. This is based on their low environmental impact and their low annual operating costs. More information about ground source geothermal heat pumps can be found here on the EPA website.

The water loop is underground and the geothermal unit is normally installed inside the home. An image of the geothermal unit with the covers removed is shown below. The blower fan and evaporator are in the upper compartment. The blower fan circulates home air through the homes ventilation duct system. Home air is pulled from the home through the return ducting back to the geo unit. Then conditioned air from the geo unit is supplied to all rooms of the home through the supply ducting.

Internal Components of a Geothermal Residential Heat Pump

The lower compartment of the geo unit contains the compressor, the coaxial heat exchanger, and other components. A more detailed view of the components in the lower compartment is shown below. These images are from Bosch residential geothermal units.

The Compressor is the tall cylindrical object with the sound proof insulation over it. The heat exchangers are on either end of the unit shown above. The various control components are contained in the metal box in front of the compressor.
