Geothermal heating and cooling uses renewable ground source energy derived from heat deep in the Earth’s crust. For every 100 meters you move below ground, the ground temperature increases approximately 3 degrees Celsius. Geothermal heating and cooling uses the abundant supply of natural and stable energy stored in the Earth for homes and business properties.
General Geothermal Heating & Cooling Questions
How does Geothermal Energy Work?
The temperature in St Louis fluctuates all the time through the changing seasons. The ground temperature that is four to six feet below the ground surface remains relatively constant all year long. The Earth absorbs around 40% – 60% of the heat from the sun, making the earth a giant solar panel. During the geothermal installation process, Hoffmann Brothers installs polyethylene pipes or loops underground by digging wells. The pipes are filled with a water solution and sealed using heat fusion. These loops run from the ground into your home to your geothermal heat pump.
How does Geothermal Energy Work in my Home or Business?
- Whether you have a horizontal, vertical, or lake closed-loop Geothermal system, your Geothermal heat pump is going to treat the earth as an energy reservoir for heating and cooling your home; during the hot Summer months, your geothermal system will remove the heat from your home or business and transfer that heat into the earth via your closed-loop system. During the cold winter months, your geothermal heat pump will utilize your closed-loop system to take the heat energy stored within the earth and move it into your home or business.
- Geothermal systems are extremely quiet. You don’t have an outdoor air conditioner that rattles or vibrates in the summertime when you are trying to enjoy the outdoors. The Heat pump is installed within your home or business and operates quietly and efficiently to maintain a comfortable indoor climate.
- Geothermal heating and air conditioning systems do not use fuel to run. Geothermal heating is flameless and, therefore, produces no health and safety concerns that come with burning fossil fuels. The US Department of Energy (DOE) along with the Environmental Protection Agency (EPA) have named geothermal systems the most environmentally friendly way to heat and cool your home.
- Because geothermal heat pump systems are so efficient, much less energy is required to heat and cool your home or business. This reduced energy requirement often means that less fossil fuels will be consumed to maintain a comfortable indoor climate. The Environmental Protection Agency (EPA) estimates that geothermal systems can reduce energy consumption- and corresponding emissions- up to 44% compared to air-source heat pumps. Furthermore, the EPA estimates up to 72% reduction in energy consumption when compared to electric resistance heating from standard HVAC equipment.
What Is A Geothermal Heat Pump?
A geothermal heat pump is an electrically-powered device that uses the Earth’s natural heat storage ability to heat and cool your home or business at significantly less energy costs.
How Efficient Is A Geothermal Heat Pump?
The geothermal heat pump is one of the most efficient residential heating and cooling systems available today, with heating efficiencies 50 to 70% higher than other heating systems and cooling efficiencies 20 to 40% higher than available air conditioners. That directly translates into savings for you on your utility bills.
How Long Will My Geothermal System Last?
Geothermal units are durable and highly reliable. The geothermal heat pumps contain fewer mechanical components, and all components are either buried in the ground or located inside the home, which protects them from outside conditions. The underground pipe carries up to a 50-year warranty.
How Noisy Is The Geothermal Heat Pump Unit?
Geothermal units are very quiet, providing a pleasant environment inside and outside of the home. Geothermal units have no noisy fan units to disturb outdoor activities, on or near the patio.
How Safe Are Geothermal Heat Pumps?
Geothermal systems are safe and protected. With no exposed equipment outdoors, children or pets cannot injure themselves or damage exterior units. Geothermal heat pumps have no open flame, flammable fuel or potentially dangerous fuel storage tanks.
What About Comfort Of Geothermal Systems?
A geothermal system moves warm air (90-105(F)) throughout your home or business via standard ductwork. An even comfort level is created because the warm air is moved in slightly higher volumes and saturates the building with warmth more evenly. This helps even out hot or cold spots and eliminates the cold air blasts common with fossil fuel furnaces.
How Effective Is This Underground System?
The buried pipe, or ground loop, is the most recent technical advancement in heat pump technology. Recently, new heat pump designs and improved buried pipe materials have been combined to make geothermal systems the most efficient heating and cooling systems available.
Are Geothermal Systems Guaranteed?
Nearly all geothermal heat pump system manufacturers offer a warranty for major components that is equivalent to the warranties for conventional heating and cooling systems. Manufacturers of plastic pipe used for ground loops warrant their products for 50 years.
Can These Systems Be Used For Commercial, Industrial, Or Apartment Requirements?
Yes. Many geothermal systems are being installed using a multitude of systems hooked up to an array of buried vertical or horizontal loops. This simplifies zone control and internal load balancing.
Geothermal Savings and Costs Questions
If you replace your standard heating and cooling system with a high efficiency Geothermal heat pump system, you stand to realize tremendous savings in your utility bills by reducing fossil fuel and electricity consumption.
