Geothermal HVAC

In contrast to traditional HVAC systems that run on natural gas, fuel oil propane, electricity or fuel oil geothermal can provide two-in-one cooling and heating. The temperatures of the earth below the surface are pretty constant all year.

Geothermal systems are made of a heatpump, underground loops and the distribution system. Find out more about this energy-efficient system’s components:.

Ground Loop

The Ground Loop is the main element to a geothermal system’s effectiveness and durability. It consists of pipes that are placed in the backyard, and then connected to the heat pump in your home. The pipes are then filled with a water-based fluid that circulates to absorb or disperse heat based on the needs of your home. The temperature of the ground is relatively constant between four and six feet below surface level, making it an ideal energy source for geothermal systems.

When the system is in heating mode, the heat transfer fluid absorbs the Earth’s heat and then transfers it to the heat pump within your home. The fluid is then pushed into the loop, where it starts circulating again. In cooling mode, the system employs the opposite method to eliminate the heat surplus and return it back to the loop where it starts the next cycle.

In closed loop systems, the piping is filled with a water-based product and buried in the ground. The solution is safe for the environment. It is not a pollutant to underground water supplies. The system can also utilize the pond or lake as a source of heat transfer fluid, making it more eco-friendly.

Depending on the available space, closed and open systems can be set up horizontally or vertically. The vertical system requires fewer trenches than a horizontal one and reduces disturbance to your landscaping. It is used in areas where soil depths are shallow or where existing landscaping needs to be maintained.

No matter what type of ground loop system you choose, it is essential to select a reliable installer. It is important to have a well-functioning and well-designed system, as geothermal systems use a lot of energy. A well-designed installation will ensure the long-term viability of your system and help you save energy costs in the long run. It is important to flush the system frequently to eliminate any minerals that could reduce the flow and effectiveness of the heat transfer liquid.

Vertical Loop

Geothermal energy is the energy derived from the Earth that is utilized to heat and cool buildings. This energy can be harnessed using underground loops that absorb heat and then transfer it into your home. The most common kind of geothermal system is called a vertical ground loop. This type of geothermal system is used most often in residential and commercial applications. This system makes use of the heat pump to transfer energy from the earth into your home or office. In the summer, it reverses to provide cooling.

The heat energy that is transferred from the ground to your house is stored in a network of buried pipes. These pipes are a key element of any geo thermal hvac system. The pipes are made from high-density polyethylene. They move the mixture of water and propylene glycol which is a food-grade antifreeze, throughout the system. The temperature of the soil or water is relatively constant only a few feet below the surface. This allows the closed-loop geothermal heat pump to work more efficiently than other heating systems such as gas furnaces and boilers.

The loops can be erected in a horizontal trench or placed into boreholes that are drilled to a depth of 100 to 400 feet. Horizontal trenches work best for large properties with lots of land vertical boreholes are suitable for homes and businesses with small spaces. The process of installing a horizontal ground loop involves digging a long trench that may take a considerable amount of time and effort. Additionally the ground needs to be compacted so that the loops have a strong grip on the soil.

A vertical loop is simpler to set up than a horizontal field. The technician drills holes of 4 inches in diameter, separated by 20 feet. Then, he installs the pipe to form an enclosed circuit. The number of holes you need will depend on your building’s size and the energy requirements.

To keep your geothermal heating and cooling system running at its peak it is crucial to properly maintain the loop fields. This means cleaning the loop fields as well as performing periodic bacteriological tests.

Horizontal Loop

Geothermal heat pumps transfer energy between your home and ground or a nearby body of water, rather than taking energy from the outside air. The reason is that the temperature of the ground and water are relatively constant, unlike outdoor air temperatures that fluctuate. The size and layout of your property will determine the type of loop you employ. The type of loop used and the method used to install it determine the efficiency and effectiveness of your geothermal system.

Horizontal geothermal systems use a series of horizontal pipes that are buried in trenches between four and six feet deep. The trenches can house up to three pipe circuits. The pipe circuits are connected to a manifold which is the central control unit. The manifold then delivers hot and cool water to your home’s heating and cooling ductwork.

Initially these pipes were installed in vertical trenches which required a larger space to surround the pipes. As technology improved, it was found that layering a single longer pipe back and forth at varying depths in shorter trenches could reduce space requirements and costs without losing performance. This led to the invention of the “slinky method” of installing horizontal geothermal circuits.

In situations where there’s not enough land available, a vertical loop can be a good alternative. It is also an option for homes situated in urban settings, where the topsoil is a bit thin and there is little if any room for horizontal loops. If your property is located in an earthquake-prone region and is unable to support a horizontal loop system, a vertical loop system could be the best choice.

If you have a lot of water in your home, ponds or lakes can be the ideal option for your home. This kind of system is similar to a horizontal or vertical ground loop geothermal heating pump, but instead of using earth to heat and cool it uses water to heat and cool. It is crucial to note that a geothermal system that uses lakes or ponds is not functional in the event of a power outage. Installing a backup generator can supply electricity during this time.


Geothermal heating is an efficient alternative to conventional methods. When it comes time to switch, homeowners have to balance upfront costs and energy savings in the long run. There are many factors to consider including the soil’s composition and the local climate. One of the most important choices is whether or not to dig ground loops or to use an external tank for hot water. The latter is less expensive, but it may not provide the same efficiency.

A desuperheater is a device that transfers heat from a geothermal heating system to your hot water tank. It is designed to work during winter, when the cooling process of the system generates excessive heat. The desuperheater utilizes this wasted heat to boost the efficiency of heating in your home. It also reduces your energy consumption by utilizing existing sources.

The best design of a desuperheater is dependent on various physical, geometric, and thermal variables. These variables include the injection angle, the temperature of the water spray, and the nozzle design. These are all aspects that affect the performance and efficiency of the desuperheater.

In a climate dominated by heating, a desuperheater can save you as much as 80% more than an ordinary water heater during the summer. This is because the desuperheater uses the energy removed from the house during the cooling process and converts it to useful heat for the hot water generator. This allows the geothermal system to create domestic hot water for 3-5 months of the year, at only a fraction of the cost of other energy sources.

The desuperheater is also able to help in winter when geothermal systems are operating at its smallest capacity. The device can add the additional heat generated by the cooling system to the domestic hot-water tank. This allows the domestic hot water tank to make use of the energy that is free, and maximizes the heating capacity of the system. The desuperheater may also be used to decrease the time that geothermal systems are in operation in a heating dominated climate.
