Geothermal is no longer just for the affluent, a reputation it once held because typical early buyers were owners of upscale homes. They wanted the quiet comfort Geothermal systems provide, and they were more than willing--and could afford--to pay the cost premium associated with early systems. This is because the extraordinarily low operating costs of GeoExchange tetco Geoethermal systems more than make up for any higher installation costs within a few years. According to the U.S. Environmental Protection Agency, Geothermal systems save homeowners 60 percent in heating costs, and 50 percent in cooling costs, compared to conventional systems. GeoExchange systems also save money in other ways. Geothermal is highly reliable, require little maintenance, and are built to last for decades. Geothermal adds considerably to the value of homes.Call Magnum 1.866.624.6868 for geoexchange geoexchange finance consulting.geoexchange@magnumpm.com
Today, homeowners in all income brackets can take advantage of the benefits of Geothermal heating and cooling. Initial costs have declined substantially as many more builders and heating and cooling contractors nationwide make Geothermal systems available, and as innovative techniques enable the loops to be installed more quickly (often in one day) and for lower cost. Magnum Geoexchange use essential innovations to ensure a complete geoexchange installation.
Many financial institutions also now allow homebuyers to qualify for larger mortgages if they purchase a house that utilizes a GeoExchange system. The reduction in monthly energy bills more than offsets the slightly higher mortgage payment. With such mortgages, homeowners with Geothermal systems can begin saving money from day one, then go on saving year after year!Magnum will help you with this task.Use Magnum DIY Geothermal Geoexchange expertise to DIY do it your self Geoexchange,1.866-magnum-u, call, 1.866.624.6868. or geoexchange@magnumpm.com
Today, the major barrier to wider use of this marvelous technology is the fact that many consumers simply are not aware it is there.
GeoExchange Geothermal is a smart investment for consumers who want a system that provides a high level of comfort and low monthly energy bills for as long as they own their homes.

Heat Pumps? Geoexchange? Geothermal? Ground source heat pumps?
- Ground Source Heat Pump
A Ground Source Heat Pump utilizes the earth for both a source of heat, and a heat sink. In the winter, the earth is used as a source of heat; in the summer the earth is used as a heat sink. Therefore, the more appropriate term is Ground Exchange Heat Pump, or more simply GeoExchange Heat Pump (GHP).
- Geothermal Heat Pump
Geothermal is an inappropriate term because it can be confused with geothermal sources. There are several installations in the U.S. where raw natural geothermal heat is used to produce electrical energy. Examples of geothermal energy are geysers and naturally occurring hot springs.
- Geothermal Water Source Heat Pump
Water Source Heat Pump is actually a very accurate term for almost all GeoExchange Heat Pumps. Unfortunately, using the term creates confusion with systems that use water as the primary conditioning medium, such as large commercial buildings that use chilled water for air conditioning. Also, technically the "water" used is almost always a mixture of an antifreeze liquid and water (closed loop systems).
- Energy Efficiency Ratio (EER)
Energy Efficiency Ratio (EER) for a refrigerant type air conditioner (or heat pump in cooling mode) is defined as Btu/h divided by kilowatt input. The EER (and its cousin SEER) is used by manufacturers to provide an efficiency benchmark of a particular unit. However, it must be understood that the EER is only valid for a given set of parameters. These parameters include outside temperature and relative humidity for air source equipment. As outside temperatures rise above the manufacturer's parameter (typically 95° F), the actual EER drops off significantly from the "rated" value. Typically, an EER can drop 20% if outside temperature increases to 110°F. (Also, available BTU output of the unit drops dramatically as temps increase over 95°F.) For this reason, it is inappropriate to compare a GeoExchange Heat Pump to a conventional refrigerant type air conditioner, or to an air source heat pump.
- Coefficient of Performance (COP)
The Coefficient of Performance (COP) is a useful benchmark for comparing heating units. It is defined as the BTU/hr output divided by kilowatt input, times a conversionfactor of 0.293. The conversion factor yields a result that is dimensionless and represents a true efficiency. Typical values for heat pumps are 3.0 — 4.0. As is the case with the EER number, the COP is also inappropriate for comparisons between GHP's and air source heat pumps. The reason is the same as for the EER number. That is, the COP for air source heat pumps is based upon a given set of parameters. These parameters include outside air temperature. Again, as outside air temperature gets colder, the actual COP lowers. With a GHP, outside air temperature has no effect on COP. This argument is noted in the 2000 ASHRAE Handbook, S7.33: "The normal procedure for evaluating COP does not provide a workable method for comparing efficiencies of dissimilar energy streams. Instead, each energy stream should be valued on the same energy basis..."

Finance Geothermal & GeoExchange (Dec 09,2006) Finacing geoexchange or geoethermal projects requires knowledge of what the system offers to the creditor as security. Geoexchange financed systems for closed loop, open loop and pond loop systems offer the reassurance that the installation products have a warranty. The geoexchange pipe guarantee far outlasts most geothermal financing terms by 20 to 80 years when installing HDPE pipe.. Heat pump manufactures can offer 10 year warranties as well, reducing GeoExchange financial risk.Using an accredited IGSHPA installer can further borrowing confidence. Project manager and construction managers of geoexchange [geothermal] jobs who use the PMI www.pmi.org ISO standards give further investor confidence.

While most are paying more for heat,
geothermal system is saving money

While most of us are paying more to heat our homes, one local developer is seeing green in more ways than one. John Billone Jr. of Flower City Management installed the area's very first geothermal heating system in the renovated Medical Arts Building downtown. He says, although the investment was substantial, it's really paying off now.
"During the peak winter system, it's saving us about $4,000 a month," says Billone.
The system originates underground: There are 72 wells under the parking lot next door. Those wells funnel water into the building.
"We have a return loop, and a supply loop," explains Billone.
Pipes take the water in through the basement, where the system harnesses that energy and converts it to heat for apartments and offices upstairs. And in the summer, the system cools the buildling. The geothermal model has helped the building garner a "Green" label, a certification reserved for a select few who are deemed energy efficient and environmentally friendly.
Inside, the emphasis is on natural light with plenty of windows and skylights. The marble on the window sills was resurrected from another part of the building. And even the paint and carpets are said to have fewer chemicals.
Billone says the Green philosophy simply makes sense. He's been asked to speak about it at several seminars. He says people seem most interested in the geothermal heating and cooling system.
"As people are starting to understand that it's difficult to control energy, I think geothermal has been something that has come to people's attention," says Billone.
The system cost $300,000 to install, but Billone expects the payback period to be less than five years. Will Geothermal Work for You? (08/22/05) ABOUT
Each year, the sun blazes down on the earth, installing 51% of its energy into the soil to be stored and, without GeoThermal sustainable energy technology, wasted. GeoExchange takes this unused energy that the sun naturally provides, and converts it into a usable form of energy that can be used to heat and cool your home year round. In general, underground temperatures remain between 5°C and 12°C year round; making GeoExchange an effective and available option to provide temperature regulation in your home. Basic GeoExchange systems are composed of 3 parts; the heat pump, heat exchangers (loops), and in-home distribution devices. Heat pumps are installed inside of the basement or technical room of a home, away from vandalism and nature. The heat exchanger systems are concealed underground or underwater to provide a “heat safe”. This “heat safe” stores energy when cooling and extracts energy when heating. Distribution systems consist in the form of air ducts which welcome hot or cool air into your home, or radiant floor tubing that brings hot or cool air up from underneath of your flooring. Both systems are effective and worry-free in regulating temperatures in your home. Depending on your situation, there are 2 basic types of loops which are available on the market today: the Open Loop and the Closed Loop.
Geothermal CLOSED LOOP SYSTEMS
Closed loop systems consist of continuous underground piping where both ends are connected to the indoor heat pump, therefore creating a continuous, sealed, closed loop. Water or a mixture of water and environmentally friendly anti-freeze continuously runs through the pipes to transfer heat between the heat pump and the earth. There are 3 types of closed loop systems that can be easily and effectively installed in your home, depending on your needs and your property. Read further to see the different types of systems and to easily see which type will serve you and your particular situation best. Geothermal Horizontal Ground Closed-Loop System
 The Horizontal Ground Closed-Loop System is easily installed and effective. A trench is dug below the frost line on the site of the home. The system is then installed “flat and wide” towards the surface of the earth. There are 2 types of loops that can be used in a horizontal ground system. Regular, straight loops may be used, or coiled polyethylene piping, called slinky coils. This choice depends on your specific situation. Depending on the size of the home to be heated, the extremity of the temperatures and the soil in your area, the number of loops and trenches will vary.
Geothermal Vertical Ground Closed-Loop System
 The Vertical Ground Closed-Corix pipe Loop System is similar in design and just as effective as the Horizontal version. Narrow and deep trenches are again dug into the yard of the home or
business where the loops are planted vertically into the hole. This is a great system to install if your house is built on a small lot or a large heat exchanger is required. Depth and number of loops is dependent on the size of the system, energy demand, and your temperature requirements . Geothermal Surface Water Closed-Loop System
 The Surface Water Closed-Loop system is extremely high in heat transfer efficiency. If there is a body of water located on your lot, such as a stream, river, or pond, this inwater installation may be the best route to take. Pipes are run underground to the water source where the loops run horizontally along the floor of the water source. Naturally, water has higher heat transfer capabilities than soil or rock, so this route is effective and recommended if possible. Geothermal OPEN LOOP SYSTEM
 The open loop system is the simplest and most cost-effective GeoExchange arrangement. Outfitted with two separate pipes that do not connect underground, open loop systems do not form a continuous pipe underground. Otherwise known as a “Pump and Dump” system, this arrangement has two, separate, vertically installed pipes which run from the heat pump to an underground aquifer. One pipe extracts the water from the ground, taking it to the in-home heat pump which removes all usable energy. Excess energy is later discharged through the other pipe and returned back to the original water source. This method is waste-free and environmentally sound. An open loop system can be easily installed on existing land, under sidewalks, parking lots, driveways, or even beneath your building. CONSULTING AND ADVICE
