Geothermal drilling has been used in the U.S for quite some time now. In fact, in the 1970’s geothermal drilling was catching on in popularity due to certain advances in drilling technology. Recently, more efficient drilling processes have allowed for more cost-effective geothermal drilling projects. This form of drilling has been historically expensive due to high temperatures and hardened sites. Geothermal energy is a resource that has remained largely untapped. However, Ameridrill Inc. has just announced some new reasons to take advantage of the heat available through geothermal drilling.
For many years, utilizing geothermal energy sources was viewed as being environmentally friendly. Geothermal heat pumps have a much lesser effect on the environment and certain systems can cut greenhouse emissions by up to 40%. However, protecting the environment is not the only advantage of geothermal energy. In fact, geothermal energy sources can drastically cut the costs of both heating and cooling expenses. Geothermal heat pumps have a much lower operating cost than most traditional heating systems. Furthermore, most existing heat pumps can be easily converted to a geothermal system.
Perhaps one of the biggest advantages of geothermal heat pumps is their durability and reliability. When properly installed, a geothermal system can last upwards of fifty years. Additionally, once a geothermal energy source has been identified, the cost of hot water can be drastically reduced.
Although geothermal drilling has become a more efficient process over the years, not all HVAC installers have the experience required to utilize this resource.
"We're particularly proud that our flagship 7 Series, the first variable capacity geothermal heat pump unit available to homeowners, was recognized with the Most Efficient designation," said Tim Litton, director of marketing at WaterFurnace. "We believe that receiving this honor for yet another product reflects that the WaterFurnace brand represents best-in-class innovation and energy efficiency."
The 700A11 utilizes WaterFurnace's InfiniSpeed technology, a soft-start variable capacity compressor, in concert with a variable speed ECM blower and variable speed loop pump. This allows the unit to scale output to exactly the level needed rather than the "high" or "low" speeds found in normal systems. The capacity range is the industry's widest and can even eliminate the need for auxiliary heat.
system piping. The latter bases heat rejecter sizing on peak loads at design conditions
and the difference between required ground heat exchanger borehole lengths for heating and cooling.
• Hybrid GHP systems can significantly reduce system first costs even when a tower needs to be purchased. Costs can be reduced by more than 50% for very highly cooling dominated applications such as the small office building in Houston (cooling-to-heating load ratio of 24:1). For applications where a suitable tower already exists (as at the Oceana study site), a hybrid system can result in system cost reductions of more than 50% even when the building is not overly cooling load dominated.
• For heavily cooling dominated sites, hybrid GHPs can result in heat pump and system energy savings compared to full GHPs when the supplementary heat rejecter is operated enough hours to reduce the average heat pump entering fluid temperature during the cooling season.
• The authors of both case studies point out that none of the hybrid system designs they examined have been optimized. A design optimization method is needed to balance GHX size, supplemental heat rejecter size and type, control strategy, and electric rate structure to achieve lowest life-cycle or first cost designs for a given location.

It is believed to be the biggest geothermal project of its kind in Scotland. Geothermal heat pumps are being used at the new Kirkwall Grammar School, Stromness Primary school, Papdale Halls, and the new developments at the Pickaquoy Centre.
Ball State University in Muncie, Ind., is on the cusp of turning on what it says will be the largest ground source heat pump in the US, if not the world. The geothermal heat pump will cut the University’s carbon footprint roughly in half, the school says. It will also eradicate almost all of its $3 million annual fuel bill, but will cost about $1 million a year in electricity to run. Heothermal heat pumps – work by running water through pipes below the frost line, which is about six feet underground in Ball State’s locale. This water sits at the soil’s constant 55 degree temperature, meaning that it can be used for heating in winter and cooling during summertime.

As much as 50% of the total geothermal heat pump market involves the use of vertical borehole subsystems. There are several different configurations of geothermal heat pump system installations involving vertical earth drilling:
* Open loop: single well for water withdrawal, water returned to a surface source
* Open loop: single well for water withdrawal, water returned to a second well
* Standing column: single well for water withdrawal and water return
* Closed loop: vertical borehole
* Direct exchange: vertical boreholes using concentric pipe systems.
A motivation for NGWA promoting these questions and the need to HVAC contractors, mechanical engineers, etc., is to direct them to NGWA-member or NGWA-certified contractors to do the drilling for geothermal heat pump installations.

Bosch Geothermal Heat Pump systems are the most energy and cost efficient systems on the market and therefore the greenest technology for heating and cooling applications. This technology uses the relatively constant temperature of the earth, which makes it extremely efficient all year long in virtually any climate.
Advantages of Bosch’s geothermal heat pumps
Bosch’s green technology is the most environmentally friendly way to cool and heat your home. The system has no carbon dioxide emissions or any other negative effects on the environment. Bosch’s geothermal installations reduce greenhouse gas emissions which are responsible for climate change.
Ground loop systems have a life expectancy in excess of 50 years. Your Bosch heat pump is manufactured with rigorous standards ensuring high
efficient operation over the life of the unit. Our residential warranty offering is among the best you will find on the market.
Lower Operating Cost
Bosch’s geothermal heat pump helps to save up to 70% on your energy bills for heating, cooling and hot water because of its more efficient operation compared to conventional systems. Simple payback could be as short as 5 to 7 years and you can experience costs savings from the beginning.
Earth Coupling Options
Geothermal heat pump systems use the earth as a heat source and heat sink. In order to transfer heat to or from the house, heat exchangers (ground loops) are installed in the ground. These consist of high density polyethylene plastic pipes. The loops are then connected to the heat pump and fluid is circulated between them transferring the heat between the heat pump and the earth.
What are the savings?
GHPs consume 25–50 percent less electricity compared to conventional HVAC equipment, so installing one is a great green home remodeling project. In other words, a GHP needs only one unit of electricity to move three units of heat compared to a ratio of 1:1 or 1:2 for other systems. GHPs can decrease energy consumption and the accompanying emissions by as much as 44 percent compared to air-source heat pumps and as much as 72 percent compared to standard electric heat. GHPs can achieve efficiencies of 300-600 percent on the coldest winter night; air source heat pumps can only reach 175-250 percent on just a cool day. GHPs also maintain an approximate 50 percent indoor humidity level, making them desirable in humid areas.
The up-front cost of geothermal as a home renewable energy source is steep. However most experts agree that you can recoup this investment in 5-10 years through lower energy bills, making it even more attractive as a green home remodeling project.
Federal, state, and local tax incentives and other programs can help offset the cost of the initial investment as well. With few moving parts, a GHP system is also durable and needs little maintenance. Many manufacturers warranty the pipes for 50 years and the pump itself usually lasts 20 years.

Geothermal heat pump
A geothermal heat pump is an efficient way to use well water. A geothermal heat pump pulls water from your well and heats it up while it is still in the pipes that connect the well to your house. The heat pump keeps that water hot using natural ground temperatures, so it is environmentally friendly.
Above ground casings
In Virginia, wells must extend above the ground by at least 12 inches. If you have a geothermal heat pump well that is set up on a closed loop and heated by a geothermal source, you do not need to adhere to this regulation.
Most wells in Virginia need to be encased in 20 feet of concrete or a similar material underground in order to protect the ground water in case of contaminants. However, closed-loop heat pump wells, which keep the water within the system, do not need to be encased.
Solar energy and geothermal heating and cooling systems have advantages and disadvantages in terms of cost, installation efficiency, seasonality, local zoning requirements and restrictions. The biggest factor is going to cost compared to the usability of systems. Solar can work without electricity, but other than that they are very similar.
Solar heat pump
Solar heat pumps work by pumping a coolant solar panels mounted on the roof. Coolant is heated by passing through the collector and then transfer to a heat exchanger. Refrigerant absorbs heat in the heat exchanger and passes through the compressor when the evaporator required airflow passes. The end result is the same as a normal heat pump. Can only heat pumps for heating be amended and used for air conditioning, refrigeration pumps do not have this ability.
Geothermal heat pump
standard parts geothermal heat pump includes a compressor, heat exchangers, air trainer and eliminate condensation on air conditioning use. All these components are usually packaged in a cabinet. "The size of the system will depend on the heating and cooling your home. Geothermal heat pumps can provide a stable domestic hot water until the pump is in the air.
There are two main types of lines - an open and closed. The most popular type used for decades was an open. But the closed lines and their variants is increasing in popularity. Lines are the backbone of the geothermal heat pump systems. They work by pumping water from a well, which is between 100-400 meters depth online to a cold heat exchanger, which either absorb or dissipate heat, depending on the desired function: heat or cold. After the underground heat has been used then pumped back to the individual becomes better. Closed loop is the same, but the water is constantly recycled.
Distribution of heated or cooled air is the same as a conventional air conditioning and heating units are available in most modern homes. The difference comes from the possible need for a system to reinforce the traditional engine-driven heating and cooling systems. The efficiency of solar systems are totally dependent on weather and climate at the time, while geothermal energy is more reliable, year-round system, almost regardless of outside temperature.
The main reason for the two systems is the initial cost for installation. Solar system will be more effective for smaller houses, while the geothermal system will be better suited for large designs, leading to unnecessarily high costs for installation of electrical circuits. Another factor for geothermal power plant land surface. Depending on the size of the line that required a wide range of fields may be needed, but a plot may be too small for the system.
The geothermal heat pump system can be either a closed or open loop piping system. Closed loop geothermal systems consist of pipes that carry the heat exchange fluid—an environmentally safe water-antifreeze mix—into the ground to be ...
