How much can I save with geothermal?See The Savings
The Waterless DX geothermal system moves heat energy to and from the earth through a closed loop of environmentally-friendly refrigerant. The system uses buried copper tubing to exchange heat energy to and from the ground delivering hot or cool air into your home. Refrigerant circulates through the ground loops and the indoor heat exchanger while the indoor air handler pushes the conditioned air through the home.
At the center of it all is the heat pump, installed inside or outside the home, which works to move refrigerant through the ground loops and throughout the heating and cooling distribution system.
By using the direct exchange method, you’re able to reduce the number of heat transfers, which directly increases your home’s heat output. In a traditional ground source geothermal design there is a total of three heat transfers, while in a DX geothermal system there are only two.
When comparing heating and cooling systems, it’s clear that the Waterless™ DX Geothermal system could save you the most.

With DX Geothermal technology dating back to 1945 when the first closed loop geothermal design was installed, you can be confident that a Waterless™ DX geothermal system will be a safe investment and perform up to your expectations.
The earth absorbs solar energy from the sun allowing the ground to remain at a nearly constant temperature, between 50 to 70 degrees Fahrenheit year around depending on your geographic location. A DX geothermal system utilizes these constant temperatures to exchange heat between your home and the earth as needed for heating and cooling.
By using the direct exchange method, you’re able to reduce the number of heat transfers, which directly increases your home’s heat output. In a traditional ground source geothermal designs there are a total of three heat transfers, while in a DX geothermal system there are only two.
A diagonal ground loop configuration is drilled at a uniform angle between 70 to 100 feet into the ground using a small drilling rig and uses between 4 to 12 loops per system. This type of configuration allows the installer to dig a three foot diameter hole at the surface. Because it only requires a small amount of space and a trench that leads to the home, less of your yard will be dug up. This results in superior efficiency even when space is limited.
The three foot hole combined with the diagonal design enables an installer to maintain proper distance between loops for proper heat transfer, while digging up less area in your yard.
Sometimes referred to as a vertical bore and other times referred to as a horizontal bore; a directional bore loop configuration is really a hybrid between both a vertical and a horizontal ground loop. The loop length will typically extend out approximately 75-125 feet in several directions, while being buried anywhere between 10 to 15 feet deep. Although this design requires a larger area of land, it also can be installed with minimal digging to your yard. Using anywhere between 4 to 12 loops per system, the loops are appropriately spaced apart. Which allows them to transfer a good amount of heat from 15 feet below the surface of the earth. The loops are pushed into the ground and fan out into a hand shaped pattern returning back to the house at one location.
A horizontal loop configuration takes up the most amount of land but allows you to dig multiple trenches on your property which eliminates the need to use grout, and can save on your installation costs when yard space is not an issue. A typical system requires 4 to 12 loops to be installed depending on the size of the system and square footage of your home.
A vertical loop configuration is dug using a drilling rig to bore 100 feet into the ground. The vertical loops are placed up and down (vertically). Using 3 to 6 loops per system, they are placed at an appropriate distance apart which allow them to transfer heat appropriately. This requires less space than horizontal loops and achieves greater efficiency when yard space is limited.

Copper has a natural heat transfer advantage over plastic. As a highly conductive material, copper is one of the best methods of transferring heat making a much more efficient ground loop heat exchanger. Copper’s thermal conductivity (k) rate is more than 600 times greater than plastic, it’s this capability that allows copper to maximize the earth’s heat for your home. As a result, smaller diameter earth loops with smaller boreholes can be less expensive to drill compared to plastic pipe alternatives.
No, A water-source geothermal system is designed to pump water through the plastic ground loop, whereas a direct exchange DX geothermal unit, it pumps refrigerant through copper tubing. A copper loop cannot connect to a water-source unit, and a plastic loop cannot connect to a direct exchange unit.
Yes! The functionality and versatility of a DX geo system allows the system to both heat and cool your home efficiently. Your indoor thermostat can easily switch the geothermal system from the heating mode or to the cooling mode.
Yes! Waterless™ direct exchange geothermal uses an EPA approved, environmentally friendly refrigerant, used in both a Direct Exchange geothermal (DX) and water source geothermal systems.
Even the EPA confirmed the safety of refrigerant in its statement about a DX geothermal system when it stated, “Refrigerant is a non toxic, inert gas, posing no direct health threat to humans–nor to ground water–and it can be used with confidence in underground heat exchangers as a part of a DX System.”
Hot water production is one of the optional benefits a direct exchange (DX) geothermal system can provide! A hot water heat exchanger can be built into a system to generate domestic hot water or hot water generation. Option #1 (the desuperheater) partially generates hot water and can supplement your hot water specifically designed to generate 100% of your domestic hot water needs. Studies done by the U.S. Department of Energy show that a geothermal system that provides heating, cooling, and 100% domestic hot water will provide the most energy savings and can reduce your homes overall utility cost more than any other heat pump design.
A hot water desuperheater will generally provide 120°F water and can supply most of the domestic water needs depending on the amount of consumption. The cost of water through the use of a desuperheater is pennies a day or can even be free.
A Waterless™ geothermal compressor unit can be installed indoors or outdoors, while the air handler is always installed indoors.
The system has a very quiet operation, and provides a pleasant environment inside the home.
Yes! This is because it works with nature, and it emits no greenhouse gases. This means no pollutants are added to the air. A geothermal simply moves a majority of the thermal energy needed to condition your home, to and from the earth, and has to generate very little energy that doesn’t already exist.
Installing a Waterless geothermal is equivalent to planting 750 trees or permanently removing 2 cars off the road.
As green building practices gain attention because of their ability to offer energy saving and lower utility bills, updated guidelines provide real estate appraisers with a method of documenting energy efficient upgrades, including geothermal energy. This allows them to better evaluate the values of green homes.
Both home appraisers and real-estate agents are educated and acknowledge a geothermal system as a renewable energy source with greater value. The EPA has stated that geothermal systems can increase the value of a home $20 for every dollar saved in heating costs per year. Allowing your home to be much more appealing for resell.
Yes and No, all contractors must perform a heat load calculation to determine if the ductwork can be utilized.
It also depends on the age of the system and your current ductwork. Most systems are sized to the cooling load, not the heating load. Therefore, ductwork may need to be installed in homes that don’t have existing or adequate air distribution system. Your home should be assessed by a contractor who can tell you the requirements and modifications needed to make it the most efficient.
There are a few minor things in order to prolong the systems life. For example, routine maintenance such as changing the filters for the air handler. It is recommended that a trained professional checks the system two years after installation. Service dates can be discussed after that point.
When installed properly, copper loops can last for many generations. Copper is one of the few metals that exists naturally in the earth as an element today. It is also a stable metal and is non-corrosive in most soil conditions.
No, copper loops have been proven to have no adverse effect on grass, tree, or shrubs. Initially there will be bare areas in the ground from inserting the loops into the bore holes, but these can be restored by planting seed or sod. The vertical/diagonal loop design requires less space than a horizontal loop design, resulting in less of the homeowner’s yard being tore up
