Cincinnati, OH Geothermal Installation

How Does Geothermal Heating Work?

Temperatures under the frost line consistently range between 45-75°F. A geothermal heating system is a unique HVAC system that uses energy stored underground to heat and cool a home. It moves the heat from the earth into the house during winter and pushes warm air from the home into the ground for cooling during summer.

Closed-loop Geothermal Heating

A popular geothermal heating system is a closed-loop. A closed-loop geothermal heating system circulates water or antifreeze through plastic or copper pipes buried in the earth or submerged in water.

There are two basic types of closed-loop geothermal heating systems used in Cincinnati, OH:

  • Horizontal ground loop systems are installed where a large enough ground area is available to dig 6 – 10-feet deep trenches for hundreds of feet.
  • Vertical ground loop geothermal systems are installed in 200 – 500-feet deep boreholes, each about 7 inches in diameter. Holes are positioned about 20 feet apart to provide ample airflow for the square footage.

The piping is connected to an indoor heat pump that passes the liquid through heat exchanger coils. Then, a fan blows the heated air into the cutting system to deliver heat throughout the structure.

The cooled liquid then travels back into the piping system, returning the heat transfer liquid underground to be heated again. The process is repeated at variable rates during system operation to ensure the desired indoor temperature.

Open-loop Geothermal Heating

Open-loop geothermal heating systems utilize clean proximal groundwater as a heat source. The water is injected into the geothermal heat pump and then expelled back into its source or another drainage well. Open-loop systems require little or no trenching or boring, which saves a lot of money on installation. However, this type of system is only possible when water quantity and quality are acceptable for the system’s needs.

Benefits of Geothermal Heating Systems

It should be no surprise that homeowners are switching to geothermal heating and cooling. There are a lot of benefits associated with geothermal heating and cooling systems, including:

  • Savings up to 65% on annual energy costs relative to conventional HVAC systems
  • Likewise, geothermal systems cut greenhouse gas emissions by up to 65%
  • Significantly quieter operation than traditional HVAC systems
  • Geothermal heat pumps last for 20 to 25 years
  • Underground loops last for up to 50 years
  • Requires surprisingly little maintenance
  • It can be installed in small areas

And that’s not all. Geothermal installation with a desuperheater allows you to utilize the excess heat generated from the system to heat your water for bathing, washing clothes, and doing dishes.

And perhaps, most attractive of all, geothermal heating and cooling systems do not use explosive gas or electrifying current to operate, meaning they keep your family safer while saving you money and maintaining comfort in your beautiful Cincinnati, Ohio home.

Where Can Geothermal Units Be Installed?

Geothermal heating systems can be custom designed to work in all climate conditions and soil types. However, there are some general property requirements to consider.

  • On average, horizontal closed-loop systems require about half an acre to produce geothermal heat. Vertical closed-loop systems can be installed via 3 to 5 boreholes about 15 feet apart.
  • Open-loop geothermal systems require a private, clean water source that should be at least 8 feet deep and of sufficient size, typically about ½-acre across.
