Imagine a home in which the temperature is always comfortable, yet the heating and cooling system is out of sight. That system performs efficiently but doesn’t require extensive maintenance or knowledge on the part of the owners.

The air smells fresh; you can hear the birds chirping and the wind rustling lazily through the trees. The home shares energy with the earth similar to the way the roots of the trees exchange the essentials of life to their leaves and branches. Sounds comfortable, doesn’t it?

Geothermal heating and cooling makes that vision a reality. Geothermal HVAC (heating, ventilating, and air conditioning) brings a building in harmony with the earth beneath, taking advantage of subterranean temperatures to provide heating in the winter and cooling in the summer.

How Geothermal Heating and Cooling Works

Outdoor temperatures fluctuate with the changing seasons but underground temperatures don’t change as dramatically, thanks to the insulating properties of the earth. Four to six feet below ground, temperatures remain relatively constant year-round. A geothermal system, which typically consists of an indoor handling unit and a buried system of pipes, called an […]

Geothermal Heating & Cooling Systems’ Loop Fields

Geothermal Heat Pump Loop Fields

A geothermal heat pump system is comprised of two components, a loop field and a heat pump. The heat pump is placed inside everyone’s house and is responsible for the heat exchange. The loop field is the process of piping which is placed underground in your yard. The loop fields last for around 50+ years long. The loop fields vary according to the climate, location of your house and size of your house. Generally, the loop field is responsible for about half of your heat pump’s cost. Loop fields can be placed vertically or horizontally. The way in which the pipe is inserted in the ground, the loop field’s orientation changes. The loop field is placed in a way in which they all work efficiently. The orientation of the loop would depend totally upon the available space, contractor’s preference and ground conditions.

Horizontal Geothermal Loop Field

Geothermal Heating and Cooling Horizontal As mentioned above, the orientation of the loop field would depend upon the space and ground conditions of your house. A horizontal loop field installation usually occurs in a place where yards have lots of space or in rural areas. The horizontal loop field installation requires a large land area as the backhoe is used […]

Geothermal Heat Pump Cost Comparison

Geothermal Heat Pump Cost Comparison

Actual costs and savings may vary from those reported. The methods of calculation and the data used are designed to approximate the total cost and savings of the GSHP system based on the weather conditions for an average year in your area. Additionally, the assumed rates of inflation and the unit prices for energy are subject to change according to the economy and your energy provider.

Annual CO2 Emissions by Technology

Geothermal heat pumps generate No Direct Emission; however, even “green” heating and cooling technologies like GSHPs produce “upstream” carbon emissions.The amount of these emissions depends on the power generation method in your area. In areas where the primary power generation technology is nuclear, hydroelectric, wind turbine or solar, the upstream carbon emissions are minimal. However, the majority of the power in the United States is generated by coal fired power plants which emit a relatively higher volume of CO2. The emissions graphs shown in the geothermal heat pump cost comparison report are adjusted based on the mix of power generation methods in your region. Note that for natural gas, propane and fuel oil, only the point of use carbon emissions from the combustion of the fuel is considered not the upstream emissions resulting from their production. […]

What Is A Geothermal Heating System?

Geothermal Heating Systems Installation Contractor Maryland Geothermal A geothermal heating system is an ultra-efficient technology which involves the use of clean, renewable ground source thermal energy to heat and cool a home. Geothermal heating is also referred to as a ground source heat pump system, and it involves tapping into the earth’s natural warmth to provide heating. The term “geothermal” has its root in the Greek language, a literal translation is “earth heat”. Accessing this stable energy source with a geothermal heating and cooling system can provide your home with efficient air conditioning, heating along with the generation of hot water. At the heart of any geothermal heating system is a geothermal heat pump, which is an electrically powered unit that exchanges thermal energy to and from the earth. A ground source heat pump takes advantage of the constant subterranean temperature of 57°F (in Maryland) and channels the heat from 300 feet underground to the geothermal heating, ventilation, and air conditioning (HVAC) system.

Geothermal Systems Act As:

  • A heat source to heat one’s residence during the winter
  • A heatsink to cool one’s residence during the summer
  • A heat source for heating water for domestic use

Geothermal Heat Pumps vs. High-Efficiency Gas Furnaces

Geothermal Heat Pumps

vs. High-Efficiency Gas Furnaces

With the rise in the erratic climate changes, households have seen several traditional methods of heating and cooling their indoor environment. There are two types of heating and cooling systems which have the highest levels of efficiency: high-efficiency gas furnaces and geothermal heat pumps. Let’s first take a look at high-efficiency gas furnaces.

High-Efficiency Gas Furnaces Are Less Energy Efficient Than Geothermal HVAC SystemsHeat is generated due to the burning of fossil fuels in this method. The creation of heat in this method requires an external source of energy to input into the furnace. A more modern take on heating and cooling systems is the Geothermal method. With this method, heat is not created; however, it is simply borrowed from the Earth and directed into your home. While both of these methods create heat efficiently, one is more cost effective.

Geothermal heat pumps prove to be the least expensive in terms of operational cost when compared to other options. Geothermal heating and cooling systems generate 5 units of heat per 1 unit of electricity used and they are significantly more efficient when compared to the cost of running a natural gas furnace or an electric heat pump. Take a look […]

As heating and cooling solution comprise around half of the energy bills, hence, it is highly popularizing in many parts of the world. The government also supports this technology by offering subsidies in some countries. But have you ever wondered who invented this technology of mining out energy from inside Earth and utilizing it for heating and cooling solutions? When was it first introduced? In this article, we will be resolving all your queries regarding the History of Geothermal Heating and Cooling solutions.

The Early Usage of Geothermal System

Historians have found that since Paleolithic times, humans have used hot springs for bathing and other purposes. It is a form of utilizing the Geothermal system. The stone pool of 3rd century BC is the oldest known hot spring spa built by Qin dynasty, China. At the beginning of AD, the water from hot springs was distributed to local houses and baths in Pompeii. Perhaps, Romans were the first to use Geothermal energy that emerged as hot springs for heating rooms and in public baths. They were also the first to commercialize Geothermal. After conquering Aquae Sulis (located in the modern […]

How Are You Getting Warm and Cozy This Winter?

Winters are the best time of the year. Nothing compares to the luxuries of life, sitting in front of a warm fire sipping hot cocoa. Warm pajamas and toasty homes make the chilly winters bearable but all of these cannot be complete without investing in the perfect heating systems for your homes. Staying warm in the winters can be a step closer with the effective geothermal systems that have been taking on the market with rage.

Geothermal systems are heating systems that use the natural temperatures of the below the earth’s surface to maintain stability in temperatures even on the coldest winter nights when the world outside is covered with snow. The underlying principle of geothermal systems is to use naturally available resources from the consistent temperatures available at the earth’s interiors, using an underground closed loop system that is efficient in saving up to 50 to 60% on your utility bills.

Why not stick to fireplaces you ask? Modern day fireplaces work on an electric circuit consuming a lot of unnecessary energy while creating high levels of pollution through the smoke generated by them. They also heat only a certain portion of your house directly exposed to the fireplace, the rest of your house remains open to the harsh winters keeping unequal temperatures within the walls […]
